145-459: A katana ( 刀, かたな , lit. "one-sided blade" ) is a Japanese sword characterized by a curved, single-edged blade with a circular or squared guard and long grip to accommodate two hands. Developed later than the tachi , it was used by samurai in feudal Japan and worn with the edge facing upward. Since the Muromachi period , many old tachi were cut from the root and shortened, and

290-454: A big and sharp point, which was advantageous for stabbing in indoor battles. During the Meiji period , the samurai class was gradually disbanded, and the special privileges granted to them were taken away, including the right to carry swords in public. The Haitōrei Edict in 1876 forbade the carrying of swords in public except for certain individuals, such as former samurai lords ( daimyō ),

435-427: A billet. At this stage, it is only slightly curved or may have no curve at all. The katana 's gentle curvature is attained by a process of differential hardening or differential quenching : the smith coats the blade with several layers of a wet clay slurry, which is a special concoction unique to each sword maker, but generally composed of clay, water and any or none of ash, grinding stone powder, or rust. This process

580-426: A blade length greater than 60.6 cm (23.86 inches) (over 2 shaku). It is characterized by its distinctive appearance: a curved, slender, single-edged blade with a circular or squared guard ( tsuba ) and long grip to accommodate two hands. With a few exceptions, katana and tachi can be distinguished from each other, if signed, by the location of the signature ( mei ) on the tang ( nakago ) . In general,

725-555: A blade. In the Kamakura period (1185–1333), high-ranking samurai wore hyogo gusari tachi (hyogo kusari no tachi, 兵庫鎖太刀) , which meant a sword with chains in the arsenal. The scabbard of the tachi was covered with a gilt copper plate and hung by chains at the waist. At the end of the Kamakura period, simplified hyogo gusari tachi came to be made as an offering to the kami of Shinto shrines and fell out of use as weapons. On

870-480: A curved tip, the tip is squared at a shear angle. The shear angle may facilitate the stabbing effectiveness of the blade, and make the process of sharpening simpler. This style of blade is commercially popular, and was used by CIA field agents in the wake of 9/11. Tantō with blunt wooden or blunt plastic blades are used to practice martial arts. Versions with a blunt metal blade are used in more advanced training and in demonstrations. Martial arts that employ

1015-559: A different manner. By the 15th century, Japanese swords, including katana , had already gained international fame by being exported to China and Korea. For example, Korea learned how to make Japanese swords by sending swordsmiths to Japan and inviting Japanese swordsmiths to Korea. According to the record of June 1, 1430 in the Veritable Records of the Joseon Dynasty , a Korean swordsmith who went to Japan and mastered

1160-471: A gently curved single-edged blade, and the structure of nakago , was completed. Its shape may reflect the changing form of warfare in Japan. Cavalry were now the predominant fighting unit and the older straight chokutō were particularly unsuitable for fighting from horseback. The curved sword is a far more efficient weapon when wielded by a warrior on horseback where the curve of the blade adds considerably to

1305-553: A great cost.". From the Heian period (794–1185), ordinary samurai wore swords of the style called kurourusi tachi (kokushitsu no tachi, 黒漆太刀) , which meant black lacquer tachi . The hilt of a tachi is wrapped in leather or ray skin, and it is wrapped with black thread or leather cord, and the scabbard is coated with black lacquer. On the other hand, court nobles wore tachi decorated with precisely carved metal and jewels for ceremonial purposes. High-ranking court nobles wore swords of

1450-523: A great flood, the spread of the Mino school, and the virtual unification of Japan by Toyotomi Hideyoshi , which made almost no difference in the steel used by each school. Japanese swords since the Shintō period often have gorgeous decorations carved on the blade and lacquered maki-e decorations on the scabbard. This was due to the economic development and the increased value of swords as arts and crafts as

1595-455: A high concentration in the burial goods of the Ōshū and Hokkaido regions. Mokusa Area was famous for legendary swordsmiths in the Heian period (AD 794–1185). They are considered as the original producers of the Japanese swords known as " Warabitetō " which can date back to the sixth to eighth centuries. " Warabitetō " gained its fame through the series of battles between Emishi people (蝦夷) and

1740-486: A living. Since 1953, Japanese swordsmiths have been allowed to work, but with severe restrictions: swordsmiths must be licensed and serve a five-year apprenticeship, and only licensed swordsmiths are allowed to produce Japanese swords ( nihonto ), only two longswords per month are allowed to be produced by each swordsmith, and all swords must be registered with the Japanese Government . Outside Japan, some of

1885-444: A long time, Japanese people have developed a unique appreciation method in which the blade is regarded as the core of their aesthetic evaluation rather than the sword mountings decorated with luxurious lacquer or metal works. It is said that there are three objects that are the most noteworthy when appreciating a blade. The first is the overall shape referred to as sugata which is the curvature, length, width, tip, and shape of tang of

2030-434: A small tantō called a kaiken in their obi , primarily for self-defense . Tantō were sometimes worn as the shōtō ( 小刀 ) in place of a wakizashi in a daishō , especially on the battlefield. Before the advent of the wakizashi/tantō combination, it was common for a samurai to carry a tachi and a tantō as opposed to a katana and a wakizashi . It has been noted that

2175-410: A smaller blade; both worn edge-up. This style is called buke-zukuri , and all daitō worn in this fashion are katana , averaging 70–74 cm (2 shaku 3 sun to 2 shaku 4 sun 5 bu) in blade length. However, Japanese swords of longer lengths also existed, including lengths up to 78 cm (2 shaku 5 sun 5 bu). It was not simply that the swords were worn by cords on a belt, as a 'style' of sorts. Such

2320-546: A statement trivializes an important function of such a manner of bearing the sword. It was a very direct example of 'form following function.' At this point in Japanese history, much of the warfare was fought on horseback. Being so, if the sword or blade were in a more vertical position, it would be cumbersome, and awkward to draw. Suspending the sword by 'cords' allowed the sheath to be more horizontal, and far less likely to bind while drawing it in that position. Abnormally long blades (longer than 3 shaku ), usually carried across

2465-406: A swordsmith signature and a file pattern engraved on tang, and a carving inscribed on the blade, which is referred to as horimono , are also the objects of appreciation. The Hon'ami clan, which was an authority of appraisal of Japanese swords, rated Japanese swords from these artistic points of view. In addition, experts of modern Japanese swords judge when and by which swordsmith school the sword

2610-421: A tanto making the length distinction somewhat arbitrary but necessary when referring to unmounted short blades. When the mounts are taken out of the equation, a tanto and wakizashi will be determined by length under or over 30 cm (12 in), unless their intended use can be absolutely determined or the speaker is rendering an opinion on the intended use of the blade. In this way, a blade formally attributed as

2755-422: A three-dimensional cross-sectional shape of an elongated pentagonal to hexagonal blade called shinogi-zukuri , a style in which the blade and the tang ( nakago ) are integrated and fixed to the hilt ( tsuka ) with a pin called mekugi , and a gentle curve. When a shinogi-zukuri sword is viewed from the side, there is a ridge line of the thickest part of the blade called shinogi between the cutting-edge side and

2900-526: A trapezoidal shape). A flat or narrowing shinogi is called shinogi-hikushi , whereas a flat blade is called a shinogi-takushi . The shinogi can be placed near the back of the blade for a longer, sharper, more fragile tip or a more moderate shinogi near the center of the blade. The sword also has an exact tip shape, which is considered an extremely important characteristic: the tip can be long ( ōkissaki ), medium ( chūkissaki ), short ( kokissaki ), or even hooked backwards ( ikuri-ōkissaki ). In addition, whether

3045-465: A true daitō and a wakizashi . A shōtō and a daitō together are called a daishō (literally, "big-little" ). The daishō was the symbolic armament of the Edo period samurai . A blade longer than two shaku is considered a daitō , or long sword. To qualify as a daitō the sword must have a blade longer than 2 shaku (approximately 24 inches or 60 centimeters) in a straight line. While there

3190-409: A unique profile, mostly dependent on the swordsmith and the construction method. The most prominent part is the middle ridge, or shinogi . In the earlier picture, the examples were flat to the shinogi, then tapering to the blade edge. However, swords could narrow down to the shinogi, then narrow further to the blade edge, or even expand outward towards the shinogi then shrink to the blade edge (producing

3335-429: A very long curved single-edged sword; uchigatana , a slightly shorter curved single-edged long sword; wakizashi , a medium-sized sword; and tantō , which is an even smaller knife-sized sword. Naginata , nagamaki , and yari , despite being polearms, are still considered to be swords, which is a common misconception; naginata, nagamaki and yari differ from swords. The type classifications for Japanese swords indicate

3480-501: A wakizashi due to length may be informally discussed between individuals as a tanto because the blade was made during an age where tanto were popular and the wakizashi as a companion sword to katana did not yet exist. The following are types of Japanese swords: There are other bladed weapons made in the same traditional manner as Japanese swords, which are not swords, but are still classified as Japanese swords ( nihontō ) (as "tō" means "blade", rather than specifically "sword") because of

3625-420: A word to describe a long sword that was different from a tachi , occurs as early as the Kamakura period. These references to " uchigatana " and " tsubagatana " seem to indicate a different style of sword, possibly a less costly sword for lower-ranking warriors. Starting around the year 1400, long swords signed with the katana- style mei were made. This was in response to samurai wearing their tachi in what

3770-401: Is a list of lengths for different types of blades: Blades whose length is next to a different classification type are described with a prefix 'O-' (for great) or 'Ko-' (for small), e.g. a Wakizashi with a length of 59 cm is called an O-wakizashi (almost a Katana) whereas a Katana of 61 cm is called a Ko-Katana (for small Katana; but note that a small accessory blade sometimes found in

3915-775: Is a school that originated in Yamato Province corresponding to present-day Nara Prefecture . Nara was the capital of ancient Japan. Since there is a legend that it was a swordsmith named Amakuni who first signed the tang of a sword, he is sometimes regarded as the founder and the oldest school. However, the founder identified in the material is Yukinobu in the Heian period . They forged the swords that were often worn by monk warriors called sōhei in Nara's large temples. The Yamato school consists of five schools: Senjuin, Shikkake, Taima, Tegai, and Hōshō . Each school forged swords under

4060-571: Is a special designation given to sword masterpieces which are listed in a compilation from the 18th century called the "Kyoho Meibutsucho". The swords listed are Koto blades from several different provinces; 100 of the 166 swords listed are known to exist today, with Sōshū blades being very well represented. The "Kyoho Meibutsucho" also listed the nicknames, prices, history and length of the Meibutsu , with swords by Yoshimitsu, Masamune, Yoshihiro, and Sadamune being very highly priced. Each blade has

4205-498: Is a theory that koshigatana (腰刀), a kind of tantō which was equipped by high ranking samurai together with tachi , developed to katana through the same historical background as sasuga , and it is possible that both developed to katana . The oldest katana in existence today is called Hishizukuri uchigatana , which was forged in the Nanbokuchō period, and was dedicated to Kasuga Shrine later. The first use of katana as

4350-459: Is a traditionally made Japanese knife ( nihontō ) that were worn by the samurai class of feudal Japan. The tantō dates to the Heian period , when it was mainly used as a weapon but evolved in design over the years to become more ornate. Tantō were used in traditional martial arts ( tantojutsu ) and in the seppuku suicide ritual. The term has seen a resurgence in the West since

4495-449: Is a well defined lower limit to the length of a daitō , the upper limit is not well enforced; a number of modern historians, swordsmiths, etc. say that swords that are over 3 shaku in blade length are "longer than normal daitō " and are usually referred to as ōdachi . The word "daitō" is often used when explaining the related terms shōtō (short sword) and daishō (the set of both large and small sword). Miyamoto Musashi refers to

4640-527: Is also traditionally used in the yubitsume ritual (cutting off part of a finger as an act of submission or atonement). American and European interest in Japanese martial arts since the war created a demand for the tantō outside Japan from the 1960s through the present time. A popular style of blade, known simply as a Tanto in the US and Europe. The blade is similar in style to the Tantō, except that instead of

4785-468: Is because the Japanese government allowed swordsmiths to make only 24 Japanese swords per person per year in order to maintain the quality of Japanese swords. Many swordsmiths after the Edo period have tried to reproduce the sword of the Kamakura period which is considered as the best sword in the history of Japanese swords, but they have failed. Then, in 2014, Kunihira Kawachi succeeded in reproducing it and won

4930-401: Is called tsuchioki . The edge of the blade is coated with a thinner layer than the sides and spine of the sword, heated, and then quenched in water (few sword makers use oil to quench the blade). The slurry causes only the blade's edge to be hardened and also causes the blade to curve due to the difference in densities of the micro-structures in the steel. When steel with a carbon content of 0.7%

5075-523: Is called a daishō . Only samurai could wear the daishō : it represented their social power and personal honour . Samurai could wear decorative sword mountings in their daily lives, but the Tokugawa shogunate regulated the formal sword that samurai wore when visiting a castle by regulating it as a daisho made of a black scabbard, a hilt wrapped with white ray skin and black string. Japanese swords made in this period are classified as shintō . In

5220-456: Is classified as a shinshintō . One of the most popular swordsmiths in Japan today is Minamoto Kiyomaro who was active in this shinshintō period. His popularity is due to his timeless exceptional skill, as he was nicknamed " Masamune in Yotsuya " after his disastrous life. His works were traded at high prices and exhibitions were held at museums all over Japan from 2013 to 2014. The idea that

5365-507: Is considered a tantō (knife). A blade longer than one shaku but less than two is considered a shōtō (short sword). The wakizashi and kodachi are in this category. The length is measured in a straight line across the back of the blade from tip to munemachi (where blade meets tang ). Most blades that fall into the "shōtō" size range are wakizashi . However, some daitō were designed with blades slightly shorter than 2 shaku . These were called kodachi and are somewhere in between

5510-408: Is derived from the fact that the central part of tang is hollowed out in the shape of an ancient Japanese tweezers ( kenuki ). In the tachi developed after kenukigata-tachi , a structure in which the hilt is fixed to the tang ( nakago ) with a pin called mekugi was adopted. As a result, a sword with three basic external elements of Japanese swords, the cross-sectional shape of shinogi-zukuri ,

5655-574: Is divided into specific time periods: Katana originates from sasuga (刺刀), a kind of tantō (short sword or knife) used by lower-ranking samurai who fought on foot in the Kamakura period (1185–1333). Their main weapon was a long naginata and sasuga was a spare weapon. In the Nanboku-chō period (1336–1392) which corresponds to the early Muromachi period (1336–1573), long weapons such as ōdachi were popular, and along with this, sasuga lengthened and finally became katana . Also, there

5800-400: Is heated beyond 750 °C (1,380 °F), it enters the austenite phase. When austenite is cooled very suddenly by quenching in water, the structure changes into martensite , which is a very hard form of steel. When austenite is allowed to cool slowly, its structure changes into a mixture of ferrite and pearlite which is softer than martensite. This process also creates the line down

5945-682: Is in charge of making scabbards, nurishi is in charge of applying lacquer to scabbards, tsukamakishi is in charge of making hilt, and tsubashi is in charge of making tsuba (hand guard). Tosho use apprentice swordsmiths as assistants. Prior to the Muromachi period, tosho and kacchushi (armorer) used surplus metal to make tsuba , but from the Muromachi period onwards, specialized craftsmen began to make tsuba . Nowadays, kinkoshi sometimes serves as shiroganeshi and tsubashi . Historically, katana have been regarded not only as weapons but also as works of art, especially for high-quality ones. For

6090-642: Is medium in size. It is often evaluated as a sword with a simple and strong impression. The Yamashiro school is a school that originated in Yamashiro Province , corresponding to present-day Kyoto Prefecture . When Emperor Kanmu relocated the capital to Kyoto in 794, swordsmiths began to gather. The founder of the school was Sanjō Munechika in the late 10th century in the Heian period. The Yamashiro school consisted of schools such as Sanjō, Ayanokōji, Awataguchi, and Rai . At first, they often forged swords in response to aristocrats' demands, so importance

6235-424: Is now called " katana style" (cutting edge up). Japanese swords are traditionally worn with the mei facing away from the wearer. When a tachi was worn in the style of a katana , with the cutting edge up, the tachi 's signature would be facing the wrong way. The fact that swordsmiths started signing swords with a katana signature shows that some samurai of that time period had started wearing their swords in

6380-400: Is the signature inscribed on to the tang of the Japanese sword. Fake signatures ("gimei") are common not only due to centuries of forgeries but potentially misleading ones that acknowledge prominent smiths and guilds, and those commissioned to a separate signer. Sword scholars collect and study oshigata , or paper tang-rubbings, taken from a blade: to identify the mei, the hilt is removed and

6525-445: The tachi would be paired with a tantō and later the katana would be paired with another shorter katana. With the advent of the katana, the wakizashi was eventually chosen by samurai as the short sword of choice over the tantō . Kanzan Satō, in his book The Japanese Sword , notes that there did not seem to be any particular need for the wakizashi , and suggests that the wakizashi may have become more popular than

6670-515: The tantō due to the wakizashi being more suited for indoor fighting. He mentions the custom of leaving the katana at the door of a castle or palace when entering while continuing to wear the wakizashi inside. The production of swords in Japan is divided into specific time periods: The tantō was invented partway through the Heian period . With the beginning of the Kamakura period , tantō were forged to be more aesthetically pleasing, and hira and uchi-sori tantō became

6815-542: The kun'yomi (Japanese reading) of the kanji 刀, originally meaning single edged blade (of any length) in Chinese , the word has been adopted as a loanword by the Portuguese . In Portuguese the designation (spelled catana ) means "large knife" or machete . The katana is generally defined as the standard sized, moderately curved (as opposed to the older tachi featuring more curvature) Japanese sword with

6960-557: The nihontō family of swords, and is distinguished by a blade length ( nagasa ) of more than 2 shaku , approximately 60 cm (24 in). Katana can also be known as dai or daitō among Western sword enthusiasts, although daitō is a generic name for any Japanese long sword , literally meaning "big sword". As Japanese does not have separate plural and singular forms, both katanas and katana are considered acceptable forms in English. Pronounced [katana] ,

7105-678: The Bisen school and Mino school produced them by division of labor. The export of katana and tachi reached its peak during this period, from the late 15th century to early 16th century when at least 200,000 swords were shipped to Ming dynasty China in official trade in an attempt to soak up the production of Japanese weapons and make it harder for pirates in the area to arm. In the Ming dynasty of China, Japanese swords and their tactics were studied to repel pirates, and wodao and miaodao were developed based on Japanese swords. From this period,

7250-631: The Keichō period of the Azuchi–Momoyama period are classified as shintō (New swords). Japanese swords from shintō are different from kotō in forging method and steel ( tamahagane ). This is thought to be because Bizen school, which was the largest swordsmith group of Japanese swords, was destroyed by a great flood in 1590 and the mainstream shifted to Mino school, and because Toyotomi Hideyoshi virtually unified Japan, uniform steel began to be distributed throughout Japan. The kotō swords, especially

7395-524: The Sengoku period (period of warring states) in the late Muromachi period, the war became bigger and ashigaru fought in a close formation using yari (spears) lent to them. Furthermore, in the late 16th century, tanegashima (muskets) were introduced from Portugal, and Japanese swordsmiths mass-produced improved products, with ashigaru fighting with leased guns. On the battlefield in Japan, guns and spears became main weapons in addition to bows. Due to

SECTION 50

7540-583: The Sengoku period ended and the peaceful Edo period began. Japanese swords are still commonly seen today; antique and modern forged swords can be found and purchased. Modern, authentic Japanese swords ( nihontō ) are made by a few hundred swordsmiths. Many examples can be seen at an annual competition hosted by the All Japan Swordsmith Association, under the auspices of the Nihontō Bunka Shinkō Kyōkai (Society for

7685-504: The Shinogi-Zukuri katana , which is a single-edged and usually curved longsword traditionally worn by samurai from the 15th century onwards. Western historians have said that Japanese katana were among the finest cutting weapons in world military history, for their intended use. Other types of Japanese swords include: tsurugi or ken , which is a straight double-edged sword; ōdachi , tachi , which are older styles of

7830-574: The Shinto period focused on reproducing the blade of a Japanese sword in the Kamakura period. There are more than 100 Japanese swords designated as National Treasures in Japan , of which the Kotō of the Kamakura period account for 80% and the tachi account for 70%. Japanese swords since shintō are different from kotō in forging method and steel. This was due to the destruction of the Bizen school due to

7975-587: The Shōwa period that swords were produced on a large scale again. Japanese military swords produced between 1875 and 1945 are referred to as guntō (military swords). During the pre- World War II military buildup, and throughout the war, all Japanese officers were required to wear a sword. Traditionally made swords were produced during this period, but in order to supply such large numbers of swords, blacksmiths with little or no knowledge of traditional Japanese sword manufacture were also recruited. In addition, supplies of

8120-414: The hamon can be seen by holding the sword in your hand and looking at it while changing the angle of the light shining on the blade. After the blade is forged, it is then sent to be polished. The polishing takes between one and three weeks. The polisher uses a series of successively finer grains of polishing stones in a process called glazing, until the blade has a mirror finish. However, the blunt edge of

8265-599: The hamon . It is often evaluated as a sword with a showy and gorgeous impression. The Sōshū school is a school that originated in Sagami Province , corresponding to present-day Kanagawa Prefecture . Sagami Province was the political center of Japan where the Kamakura shogunate was established in the Kamakura period. At the end of the 13th century, the Kamakura shogunate invited swordsmiths from Yamashiro school and Bizen school, and swordsmiths began to gather. Shintōgo Kunimitsu forged experimental swords by combining

8410-422: The katana is often given a matte finish to emphasize the hamon . Japanese swords are generally made by a division of labor between six and eight craftsmen. Tosho ( Toko , Katanakaji ) is in charge of forging blades, togishi is in charge of polishing blades, kinkosi ( chokinshi ) is in charge of making metal fittings for sword fittings, shiroganeshi is in charge of making habaki (blade collar), sayashi

8555-426: The katana style where the blade was worn thrust through the belt, edge up. The tachi was worn slung across the left hip. The signature on the tang of the blade was inscribed in such a way that it would always be on the outside of the sword when worn. This characteristic is important in recognizing the development, function, and different styles of wearing swords from this time onwards. When worn with full armour,

8700-404: The mei should be carved into the side of the nakago which would face outward when the sword was worn. Since a tachi was worn with the cutting edge down, and the katana was worn with the cutting edge up, the mei would be in opposite locations on the tang. Western historians have said that katana were among the finest cutting weapons in world military history. However, the main weapons on

8845-401: The tachi would be accompanied by a shorter blade in the form known as koshigatana (腰刀, "waist sword"); a type of short sword with no handguard, and where the hilt and scabbard meet to form the style of mounting called an aikuchi ("meeting mouth"). Daggers ( tantō ), were also carried for close combat fighting as well as carried generally for personal protection. By the 11th century during

SECTION 60

#1732780819128

8990-470: The tang ( nakago ) of many old tachi were cut and shortened into katana . This kind of remake is called suriage (磨上げ). For example, many of the tachi that Masamune forged during the Kamakura period were converted into katana , so his only existing works are katana and tantō . From around the 16th century, many Japanese swords were exported to Thailand , where katana-style swords were made and prized for battle and art work, and some of them are in

9135-454: The 1980s as referring to a point style of modern tactical knives , designed for piercing or stabbing, though the style isn't present on any traditional tantō. A Tanto knife may refer to an American style of blade based of the Japanese tantō , usually with a squared rather than curved ved tip. The tantō is a single or double edged dagger with a length between 15 and 30 cm (6 and 12 in) (1 Japanese shaku ). The tantō

9280-530: The Azuchi-Momoyama period to the Edo period started, katana -forging also developed into a highly intricate and well-respected art form. Lacquered saya (scabbards), ornate engraved fittings, silk handles and elegant tsuba (handguards) were popular among samurai in the Edo period, and eventually (especially when Japan was in peace time), katana became more cosmetic and ceremonial items than practical weapons. The Umetada school led by Umetada Myoju who

9425-412: The Bizen school swords made in the Kamakura period, had a midare-utsuri like a white mist between hamon and shinogi , but in the swords from shintō it has almost disappeared. In addition, the whole body of the blade became whitish and hard. Almost no one was able to reproduce midare-utsurii until Kunihira Kawachi reproduced it in 2014. As the Sengoku period (period of warring states) ended and

9570-566: The Heian period, Japanese swords had already been exported to neighboring countries in Asia. For example, in the poem "The Song of Japanese Swords" Ouyang Xiu , a statesman of the Song dynasty in China, described Japanese swords as "It is a treasured sword with a scabbard made of fragrant wood covered with fish skin, decorated with brass and copper, and capable of exorcising evil spirits. It is imported at

9715-475: The Imperial Court began wearing the set of tachi and tantō once more, and the number of tantō in existence increased dramatically. After World War II, a restriction on sword forging caused tantō manufacture to fall drastically. Tantō remained in use among twentieth century yakuza (gangsters) since they could be carried as a concealed weapon more easily than a katana. A tantō

9860-600: The Japanese government started requiring the use of special stamps on the tang ( nakago ) to distinguish these swords from traditionally made swords. During this period of war, older antique swords were remounted for use in military mounts. Presently, in Japan, shōwatō are not considered to be "true" Japanese swords, and they can be confiscated. Outside Japan, however, they are collected as historical artifacts. Between 1945 and 1953, sword manufacture and sword-related martial arts were banned in Japan. Many swords were confiscated and destroyed, and swordsmiths were not able to make

10005-471: The Japanese steel ( tamahagane ) used for swordmaking were limited, so several other types of steel were also used. Quicker methods of forging were also used, such as the use of power hammers , and quenching the blade in oil, rather than hand forging and water. The non-traditionally made swords from this period are called shōwatō , after the regnal name of the Emperor Hirohito , and in 1937,

10150-555: The Kamakura period, and it developed to the largest school in the history of Japanese swords. Kanemitsu and Nagayoshi of the Osafune school were apprentices to Masamune of the Sōshū school, the greatest swordsmith in Japan. While they forged high-quality swords by order, at the same time, from the Muromachi period, when wars became large-scale, they mass-produced low-quality swords for drafted farmers and for export. The Bizen school had enjoyed

10295-457: The Kamakura, Nambokucho, or Muromachi eras. Suishinshi Masahide was a main contributor towards the forging of tantō during this age. There were now only tantō predating the Edo period being used in combat; tantō forged during the late Edo period were not combative weapons. Many tantō were forged before World War II , due to the restoration of the Emperor to power. Members of

10440-579: The Masamune Prize, the highest honor as a swordsmith. No one could win the Masamune Prize unless he made an extraordinary achievement, and in the section of tachi and katana , no one had won for 18 years before Kawauchi. Katana are distinguished by their type of blade: In addition to these, there are various other types of blades with different shapes, such as Osoraku-zukuri , Unokubi-zukuri , and Kammuri-otoshi-zukuri . Typical features of Japanese swords represented by katana and tachi are

10585-593: The Promotion of Japanese Sword Culture). However, to maintain the quality of Japanese swords, the Japanese government limits the number of Japanese swords a swordsmith can make in a year to 24 (up to 2 swords per month). Therefore, many of the swords called "Japanese sword" distributed around the world today are made in China, and the manufacturing process and quality are not authorized. Many old Japanese swords can be traced back to one of five provinces, each of which had its own school, traditions, and "trademarks" (e.g.,

10730-413: The Sōshū school gathered in Mino. The Mino school became the largest production area of Japanese swords after the Bizen school declined due to a great flood. The production rate of katana was high, because it was the newest school among five big schools. Their swords are often characterized by a slightly higher central ridge and a thinner back. There are irregular fingerprint-like patterns on the surface of

10875-747: The Tamatsukuri Fuju 諷誦,Houji 寶次 and one from Gassan signing just Gassan 月山. According to the Nihonto Meikan, the Ōshū swordsmith group consists of the Mokusa (舞草), the Gassan (月山) and the Tamatsukuri (玉造), later to become the Hoju (寶壽) schools. Ōshū swords appear in various old books of this time, for example Heiji Monogatari 平治物語 (Tale of Heiji), Konjaku Monogatari 今昔物語 (Anthology of tales from

11020-648: The Yamato-chotei government (大 和朝廷) in the late eighth century. Using " Warabitetō ," the small number of Emishi soldiers could resist against the numerous Yamato-chotei army over a Thirty-Eight Years' War (三十八年戦争) (AD 770–811). The Meikan describes that from earlier time there was a list of forty-two famous swordsmiths in the Toukou Meikan 刀工銘鑑 at Kanchiin 観智院. Eight of the swordsmiths on this list were from Ōshū schools. Five from Mokusa being Onimaru 鬼丸, Yoyasu 世安, Morifusa 森房, Hatafusa 幡房 and Gaan 瓦安, two from

11165-597: The authority of the rating is still valid today. In 1719, Tokugawa Yoshimune , the 8th shogun of the Tokugawa shogunate , ordered Hon'ami Kōchū, who was an authority of sword appraisal, to record swords possessed by daimyo all over Japan in books. In the completed " Kyōhō Meibutsu Chō " (享保名物帳) 249 precious swords were described, and additional 25 swords were described later. The list also includes 81 swords that had been destroyed in previous fires. The precious swords described in this book were called " Meibutsu " (名物) and

11310-401: The average blade suffered greatly. As the end of the period neared, the average blade narrowed and the curvature shallowed. Katana originate from sasuga ( 刺刀 ) , a kind of tantō used by lower-ranking samurai who fought on foot in the Kamakura period. Their main weapon was a long naginata , with the sasuga as a spare weapon. In the Nanboku-chō period , which corresponds to

11455-401: The back side. This shinogi contributes to lightening and toughening of the blade and high cutting ability. Katana are traditionally made from a specialized Japanese steel called tamahagane , which is created from a traditional smelting process that results in several, layered steels with different carbon concentrations. This process helps remove impurities and even out the carbon content of

11600-427: The back, are called ōdachi or nodachi . The word ōdachi is also sometimes used as a synonym for Japanese swords. Odachi means "great sword", and Nodachi translates to "field sword". These greatswords were used during war, as the longer sword gave a foot soldier a reach advantage. These swords are now illegal in Japan. Citizens are not allowed to possess an odachi unless it is for ceremonial purposes. Here

11745-511: The base or center, and have a sparkle on the surface of the blade, with the hamon being straight and the grains on the boundary of the hamon being small. It is often evaluated as a sword with an elegant impression. The Bizen school is a school that originated in Bizen Province , corresponding to present-day Okayama Prefecture . Bizen has been a major production area of high-quality iron sand since ancient times. The Ko-bizen school in

11890-422: The battlefield in the Sengoku period in the 16th century were yumi (bow) , yari (spear) , and tanegashima (gun) , and katana and tachi were used only for close combat . During this period, the tactics changed to a group battle by ashigaru (foot soldiers) mobilized in large numbers, so naginata and tachi became obsolete as weapons on the battlefield and were replaced by yari and katana . In

12035-491: The beginning of the 8th century were from the Mokusa school, listing over 100 Mokusa smiths before the beginning of the Kamakura period. Archaeological excavations of the Ōshū Tohoku region show iron ore smelting sites dating back to the early Nara period. The Tohoku region and indeed the whole Ōshū district in the 8th century was controlled and populated by the Emishi. Archaeological evidence of recovered Warabitetō (蕨手刀) show

12180-494: The blade at the root was crushed and converted into a katana . The specific term for katana in Japan is uchigatana (打刀) and the term katana (刀) often refers to single-edged swords from around the world. The word katana first appears in Japanese in the Nihon Shoki of 720. The term is a compound of kata ("one side, one-sided") + na ("blade"), in contrast to the double-sided tsurugi . The katana belongs to

12325-406: The blade of a sword in the Kamakura period is the best has been continued until now, and as of the 21st century, 80% of Japanese swords designated as National treasure in Japan were made in the Kamakura period, and 70% of them were tachi . The arrival of Matthew Perry in 1853 and the subsequent Convention of Kanagawa caused chaos in Japanese society. Conflicts began to occur frequently between

12470-506: The blade, the hamon are various, and the grain on the border of the hamon are hardly visible. The production of swords in Japan is divided into specific time periods: jōkotō (ancient swords, until around 900 A.D.), kotō (old swords from around 900–1596), shintō (new swords 1596–1780), shinshintō (new new swords 1781–1876), gendaitō (modern or contemporary swords 1876–present) Early examples of iron swords were straight tsurugi , chokutō and others with unusual shapes, some of

12615-467: The carvings in the hilts around this time. The hamon (line of temper) is similar to that of the tachi , except for the absence of choji-midare , which is nioi and utsuri . Gunomi-midare and suguha are found to have taken its place. During the era of the Northern and Southern Courts , the tantō were forged to be up to 40 centimetres (16 in) in length, as opposed to

12760-400: The changes in fighting styles in these wars, the tachi and naginata became obsolete among samurai, and the katana , which was easy to carry, became the mainstream. The dazzling looking tachi gradually became a symbol of the authority of high-ranking samurai. On the other hand, kenjutsu (swordsmanship) that makes use of the characteristics of katana was invented. The quicker draw of

12905-454: The collections of the Thai royal family. From the late Muromachi period (Sengoku period) to the early Edo period , samurai were sometimes equipped with a katana blade pointing downwards like a tachi . This style of sword is called handachi , "half tachi ". In handachi , both styles were often mixed, for example, fastening to the obi was katana style, but metalworking of the scabbard

13050-485: The combination of a blade and its mounts as this, then, determines the style of use of the blade. An unsigned and shortened blade that was once made and intended for use as a tachi may be alternately mounted in tachi koshirae and katana koshirae. It is properly distinguished, then, by the style of mount it currently inhabits. A long tanto may be classified as a wakizashi due to its length being over 30 cm (12 in); however, it may have originally been mounted and used as

13195-621: The criteria for selection were artistic elements, origins and legends. The list of "Meibutsu" includes 59 swords made by Masamune , 34 by Awataguchi Yoshimitsu and 22 by Go Yoshihiro, and these three swordsmiths were considered special. Daimyo hid some swords for fear that they would be confiscated by the Tokugawa Shogunate, so even some precious swords were not listed in the book. For example, Daihannya Nagamitsu and Yamatorige , which are now designated as National Treasures, were not listed. Japanese sword The word katana

13340-413: The crystal particles formed at the boundary of hamon. Depending on the size of the particles, they can be divided into two types, a nie and a nioi , which makes them look like stars or mist. The pattern, nie and nioi of the hamon are generally difficult to see, and the viewer usually holds the sword in his hand, changing the angle of the light as it hits the blade. In addition to these three objects,

13485-472: The cutting edge of tip) types. Kissaki usually have a curved profile, and smooth three-dimensional curvature across their surface towards the edge—though they are bounded by a straight line called the yokote and have crisp definition at all their edges. While the straight tip on the "American tanto" is identical to traditional Japanese fukura, two characteristics set it apart from Japanese sword makes: The absolute lack of curve only possible with modern tools, and

13630-460: The design originated in America. A hole is punched through the tang nakago , called a mekugi-ana . It is used to anchor the blade using a mekugi , a small bamboo pin that is inserted into another cavity in the handle tsuka and through the mekugi-ana, thus restricting the blade from slipping out. To remove the handle one removes the mekugi. The swordsmith's signature mei is carved on

13775-411: The downward force of a cutting action. Early models had uneven curves with the deepest part of the curve at the hilt . As eras changed the center of the curve tended to move up the blade. The tachi is a sword which is generally larger than a katana , and is worn suspended with the cutting edge down. This was the standard form of carrying the sword for centuries, and would eventually be displaced by

13920-430: The early Muromachi period, long weapons such as ōdachi were popular, and along with this, the sasuga lengthened, taking its form as the katana. Approximately 250 years of peace accompanied the unification of Japan , in which there was little need for blades. In this period, both the katana and wakizashi were invented, taking the place of the tantō and tachi as the most-used pair of weapons, and

14065-439: The forces of sonnō jōi (尊王攘夷派), who wanted to overthrow the Tokugawa Shogunate and rule by the Emperor, and the forces of sabaku (佐幕派), who wanted the Tokugawa Shogunate to continue. These political activists, called the shishi (志士), fought using a practical katana , called the kinnōtō (勤皇刀) or the bakumatsut ō (幕末刀). Their katana were often longer than 90 cm (35.43 in) in blade length, less curved, and had

14210-504: The forging technology of Yamashiro school and Bizen school. Masamune , who learned from Shintōgo Kunimitsu, became the greatest swordsmith in Japan. From the lessons of the Mongol invasion of Japan , they revolutionized the forging process to make stronger swords. Although this forging method is not fully understood to date, one of the elements is heating at higher temperatures and rapid cooling. Their revolution influenced other schools to make

14355-513: The front edge of the tip is more curved ( fukura-tsuku ) or (relatively) straight ( fukura-kareru ) is also important. The kissaki (point) is not usually a "chisel-like" point, and the Western knife interpretation of a "tantō point" is rarely found on true Japanese swords; a straight, linearly sloped point has the advantage of being easy to grind, but less stabbing/piercing capabilities compared to traditional Japanese kissaki Fukura (curvature of

14500-597: The grains at the boundary of the hamon are large. The Mino school is a school that originated in Mino Province , corresponding to present-day Gifu Prefecture . Mino Province was a strategic traffic point connecting the Kanto and Kansai regions, and was surrounded by powerful daimyo (feudal lords). The Mino school started in the middle of the Kamakura period, when swordsmiths of the Yamato school who learned from

14645-414: The highest prosperity for a long time, but declined rapidly due to a great flood which occurred in the late 16th century during the Sengoku period . Their swords are often characterized as curved from the base, with irregular fingerprint-like patterns on the surface of the blade, while the hamon has a flashy pattern like a series of cloves , and there is little grain but a color gradient at the boundary of

14790-434: The highest quality swords, but this technique was lost before the Azuchi–Momoyama period ( Shintō period). The Sōshū school declined after the fall of the Kamakura shogunate. Their swords are often characterized by a shallow curve, a wide blade to the back, and a thin cross-section. There are irregular fingerprint-like patterns on the surface of the blade, the hamon has a pattern of undulations with continuous roundness, and

14935-470: The last, when present, is sometimes a variation of 'made by', or, 'respectfully'. The date will be inscribed near the mei, either with the reign name; the Zodiacal Method; or those calculated from the reign of the legendary Emperor Jimmu , dependent upon the period. What generally differentiates the different swords is their length. Japanese swords are measured in units of shaku . Since 1891,

15080-464: The late 14th and early 15th centuries, katana blades tended to have lengths between 70 and 73 centimetres (28 and 29 in). During the early 16th century, the average length dropped about 10 centimetres (3.9 in), approaching closer to 60 centimetres (24 in). By the late 16th century, the average length had increased again by about 13 centimetres (5.1 in), returning to approximately 73 centimetres (29 in). Swords forged after 1596 in

15225-405: The late 18th century, swordsmith Suishinshi Masahide criticized that the present katana blades only emphasized decoration and had a problem with their toughness. He insisted that the bold and strong kotō blade from the Kamakura period to the Nanboku-chō period was the ideal Japanese sword, and started a movement to restore the production method and apply it to Katana . Katana made after this

15370-515: The long sword in The Book of Five Rings . He is referring to the katana in this, and refers to the nodachi and the odachi as "extra-long swords". Before about 1500 most swords were usually worn suspended from cords on a belt, edge-down. This style is called jindachi-zukuri , and daitō worn in this fashion are called tachi (average blade length of 75–80 cm). From 1600 to 1867, more swords were worn through an obi (sash), paired with

15515-539: The market. These types of swords are typically mass-produced and made with a wide variety of steels and methods. According to the Parliamentary Association for the Preservation and Promotion of Japanese Swords, organized by Japanese Diet members, many katana distributed around the world as of the 21st century are fake Japanese swords made in China. The Sankei Shimbun analyzed that this

15660-661: The method of making Japanese swords presented a Japanese sword to the King of Korea and was rewarded for the excellent work which was no different from the swords made by the Japanese. Traditionally, yumi (bows) were the main weapon of war in Japan, and tachi and naginata were used only for close combat. The Ōnin War in the late 15th century in the Muromachi period expanded into a large-scale domestic war, in which employed farmers called ashigaru were mobilized in large numbers. They fought on foot using katana shorter than tachi . In

15805-486: The mid Heian period was the originator. The Bizen school consisted of schools such as Ko-bizen, Fukuoka-ichimonji, Osafune, and Hatakeda . According to a sword book written in the Kamakura period, out of the 12 best swordsmiths in Japan who were convened by the Retired Emperor Go-Toba , 10 were from the Bizen school. Great swordsmiths were born one after another in the Osafune school which started in

15950-581: The middle of the Heian period (794–1185), samurai improved on the Warabitetō to develop Kenukigata-tachi ( ja:毛抜形太刀 ) -early Japanese sword-. To be more precise, it is thought that the Emishi improved the warabitetō and developed Kenukigata-warabitetō ( ja:毛抜形蕨手刀 ) with a hole in the hilt and kenukigatatō ( ja:毛抜形刀 ) without decorations on the tip of the hilt, and the samurai developed kenukigata-tachi based on these swords. Kenukigata-tachi , which

16095-564: The military, and the police. Skilled swordsmiths had trouble making a living during this period as Japan modernized its military, and many swordsmiths started making other items, such as farm equipment, tools, and cutlery. The craft of making swords was kept alive through the efforts of some individuals, notably Miyamoto Kanenori (宮本包則, 1830–1926) and Gassan Sadakazu (月山貞一, 1836–1918), who were appointed Imperial Household Artist . The businessman Mitsumura Toshimo (光村利藻, 1877－1955) tried to preserve their skills by ordering swords and sword mountings from

16240-415: The modern katanas being produced by western swordsmiths use modern steel alloys, such as L6 and A2 . These modern swords replicate the size and shape of the Japanese katana and are used by martial artists for iaidō and even for cutting practice ( tameshigiri ). Mass-produced swords including iaitō and shinken in the shape of katana are available from many countries, though China dominates

16385-513: The modern Japanese shaku is approximately equal to a foot (11.93 inches), calibrated with the meter to equal exactly 10 meters per 33 shaku (30.30 cm). However, the historical shaku was slightly longer (13.96 inches or 35.45 cm). Thus, there may sometimes be confusion about the blade lengths, depending on which shaku value is being assumed when converting to metric or U.S. customary measurements. The three main divisions of Japanese blade length are: A blade shorter than one shaku

16530-468: The most popular styles. Near the middle of the Kamakura period, more tantō artisans were seen, increasing the abundance of the weapon, and the kanmuri-otoshi style became prevalent in the cities of Kyoto and Yamato. Because of the style introduced by the tachi in the late Kamakura period, tantō began to be forged longer and wider. The introduction of the Hachiman faith became visible in

16675-571: The normal one shaku (about 30 cm (12 in)) length. The blades became thinner between the ura and the omote , and wider between the ha and mune . At this point in time, two styles of hamon were prevalent: the older style, which was subtle and artistic, and the newer, more popular style. With the beginning of the Muromachi period , constant fighting caused the mass production of blades, meaning that with higher demand, lower-quality blades were manufactured. Blades that were custom-forged still were of exceptional quality, but

16820-508: The number of tantō forged was severely decreased. Since this period, tantō have often been carved with splendid decorations. Of the tantō and wakizashi forged during this period, three masterpieces are called the Nihon santō (Three Blades in Japan) . There were still a few tantō being forged during the late Edo period, and the ones that were forged reflected the work of

16965-511: The number of people wearing a funny looking Tachi 太刀 is increasing." In "Kauyagokau" 高野御幸 1124AD :" when emperor Shirakawa 白河法皇 visited Kouyasan 高 野山, Fujiwara Zaemon Michisue 藤原左衛門通季 was wearing a Fushū sword “ In “Heihanki" 兵範記 1158AD there was a line that mentioned the Emperor himself had Fushū Tachi." It seems that during the late Heian the Emishi-to was gaining popularity in Kyoto. In

17110-414: The other hand, in the Kamakura period, there was a type of tachi called hirumaki tachi (蛭巻太刀) with a scabbard covered with metal, which was used as a weapon until the Muromachi period. The meaning was a sword wrapped around a leech, and its feature was that a thin metal plate was spirally wrapped around the scabbard, so it was both sturdy and decorative, and chains were not used to hang the scabbard around

17255-430: The part close to the cutting edge side of a planar blade, gradually appeared. Swords of this period are classified as jōkotō and are often referred to in distinction from Japanese swords. The direct predecessor of the tachi (太刀) has been called Warabitetō ( ja:蕨手刀 ) by the Emishi (Not to be confused with Ainu ) of Tohoku . The Nihonto Meikan shows the earliest and by far the largest group of Ōshū smiths from

17400-517: The past), Kojidan 古事談 (Japanese collection of Setsuwa 説話), and Gikeiki 義経記 (War tale that focuses on the legends of Minamoto no Yoshitsune 源義経 and his followers). Ōshū swordsmiths appeared in books in quite early times compared to others. Tales in these books tell of the Emishi-to in the capital city and these swords seem to have been quite popular with the Bushi. Maybe a badge of honour being captured weapons. For example, In "Nihongiryaku" 日本紀略 983AD :"

17545-452: The relatively peaceful Edo period , katana increased in importance as a weapon, and at the end of the Edo period, shishi (political activists) fought many battles using katana as their main weapon. Katana and tachi were often used as gifts between daimyo (feudal lord) and samurai, or as offerings to the kami enshrined in Shinto shrines , and symbols of authority and spirituality of samurai. The production of swords in Japan

17690-399: The sheath of a long sword is also a "kogatana" (小刀) ). Since 1867, restrictions and/or the deconstruction of the samurai class meant that most blades have been worn jindachi-zukuri style, like Western navy officers. Since 1953, there has been a resurgence in the buke-zukuri style, permitted only for demonstration purposes. In modern times the most commonly known type of Japanese sword is

17835-410: The sides of the blade called the hamon , which is made distinct by polishing. Each hamon and each smith's style of hamon is distinct. Hamon does not refer to the white area on the side of the blade. The white part is the part that is whitened by a polishing process called hadori to make it easier to see the hamon , and the actual hamon is a fuzzy line within the white part. The actual line of

17980-414: The steel. The age of the steel plays a role in the ability to remove impurities, with older steel having a higher oxygen concentration, being more easily stretched and rid of impurities during hammering, resulting in a stronger blade. The smith begins by folding and welding pieces of the steel several times to work out most of the differences in the steel. The resulting block of steel is then drawn out to form

18125-505: The style called kazari tachi or kaza tachi (飾太刀, 飾剣), which meant decorative tachi , and lower-ranking court nobles wore simplified kazatachi swords of the style called hosodachi (細太刀), which meant thin tachi . The kazatachi and hosodachi worn by nobles were initially straight like a chokutō , but since the Kamakura period they have had a gentle curve under the influence of tachi . Since tachi worn by court nobles were for ceremonial use, they generally had an iron plate instead of

18270-493: The styles and techniques were derived from Chinese dao , and some directly imported through trade. The swords of this period were a mixture of swords of Japanese original style and those of Chinese style brought to Japan via the Korean Peninsula and East China Sea. The cross-sectional shape of the blades of these early swords was an isosceles triangular hira-zukuri , and the kiriha-zukuri sword, which sharpened only

18415-407: The supervision of a different temple. In the middle of the Muromachi period , swordsmiths moved to various places such as Mino , and the school disappeared. Their swords are often characterized by a deep curve, a narrow width from blade to back, a high central ridge, and a small tip. There are direct lines on the surface of the blade, the hamon is linear, and the grain at the boundary of the hamon

18560-448: The sword and strike the enemy in a single motion. Previously, the curved tachi had been worn with the edge of the blade facing down and suspended from a belt. From the 15th century, low-quality swords were mass-produced under the influence of the large-scale war. These swords, along with spears, were lent to recruited farmers called ashigaru and swords were exported. Such mass-produced swords are called kazuuchimono , and swordsmiths of

18705-413: The sword is held point side up. The mei is chiseled onto the tang on the side which traditionally faces away from the wearer's body while being worn; since the katana and wakizashi are always worn with the cutting edge up, the edge should be held to the viewer's left. The inscription will be viewed as kanji on the surface of the tang: the first two kanji represent the province; the next pair is the smith; and

18850-429: The sword was well suited to combat where victory depended heavily on short response times. (The practice and martial art for drawing the sword quickly and responding to a sudden attack was called battōjutsu , which is still kept alive through the teaching of iaido .) The katana further facilitated this by being worn thrust through a belt-like sash ( obi ) with the sharpened edge facing up. Ideally, samurai could draw

18995-417: The sword. The second is a fine pattern on the surface of the blade, which is referred to as hada or jigane . By repeatedly folding and forging the blade, fine patterns such as fingerprints, tree rings and bark are formed on its surface. The third is hamon . Hamon is a fuzzy line in the white pattern of the cutting edge produced by quenching and tempering. The object of appreciation is the shape of hamon and

19140-742: The swords from Mino province were "from the start famous for their sharpness"). These schools are known as Gokaden (The Five Traditions). In the Kotō era there were several other schools that did not fit within the Five Traditions or were known to mix elements of each Gokaden , and they were called wakimono (small school). There were 19 commonly referenced wakimono . The number of swordsmiths of Gokaden , as confirmed by signatures and documents, were 4005 in Bizen, 1269 in Mino, 1025 in Yamato, 847 in Yamashiro and 438 in Sōshū. These traditions and provinces are as follows: The Yamato school

19285-516: The swordsmiths and craftsmen. He was especially enthusiastic about collecting sword mountings, and he collected about 3,000 precious sword mountings from the end of the Edo period to the Meiji period. About 1,200 items from a part of his collection are now in the Nezu Museum . Military action by Japan in China and Russia during the Meiji period helped revive interest in swords, but it was not until

19430-640: The tang. In Japanese, the scabbard is referred to as a saya , and the handguard piece, often intricately designed as an individual work of art—especially in later years of the Edo period —was called the tsuba . Other aspects of the mountings ( koshirae ) , such as the menuki (decorative grip swells), habaki (blade collar and scabbard wedge), fuchi and kashira (handle collar and cap), kozuka (small utility knife handle), kogai (decorative skewer-like implement), saya lacquer, and tsuka-ito (professional handle wrap, also named tsukamaki ), received similar levels of artistry. The mei

19575-426: The temperature and timing of the heating and cooling of the blade, resulting in a lighter but more robust blade. They also made the curve of the blade gentle, lengthened the tip linearly, widened the width from the cutting edge to the opposite side of the blade, and thinned the cross section to improve the penetration and cutting ability of the blade. Tant%C5%8D A tantō ( 短刀 , ' short blade ' )

19720-410: The use of the word "tanto" in the nomenclature of the western tribute is merely a nod to the Japanese word for knife or short sword, rather than a tip style. Although it is not commonly known, the "chisel point" kissaki originated in Japan. Examples of such are shown in the book The Japanese Sword by Kanzan Sato. Because American bladesmiths use this design extensively it is a common misconception that

19865-455: The waist. The Mongol invasions of Japan in the 13th century during the Kamakura period spurred further evolution of the Japanese sword. The swordsmiths of the Sōshū school represented by Masamune studied tachi that were broken or bent in battle, developed new production methods, and created innovative Japanese swords. They forged the blade using a combination of soft and hard steel to optimize

20010-415: The way they are made in a similar manner to Japanese swords: Other edged weapons or tools that are made using the same methods as Japanese swords: Each Japanese sword is classified according to when the blade was made.: Historically in Japan, the ideal blade of a Japanese sword has been considered to be the kotō in the Kamakura period , and the swordsmiths from the Edo period to the present day from

20155-455: Was tachi style. In the Muromachi period, especially the Sengoku period, people such as farmers, townspeople, and monks could have a sword.
