The dates to the Heian period, when it was mainly used as a weapon but evolved in design over the years to become more ornate. were used in traditional martial arts () and in the ''seppuku'' suicide ritual. The term has seen a resurgence in the West since the 1980s as referring to a point style of modern tactical knives, designed for piercing or stabbing, though the style is not present on any traditional tantō.

A Tanto knife may refer to an American style of blade based of the Japanese , usually with a squared rather than curved tip.

History of in Japan

The production of swords in Japan is divided into specific time periods:
* Jōkotō (ancient swords, until around 900 AD)
* Kotō (old swords from around 900–1596)
* Shintō (new swords 1596–1780)
* Shinshintō (new new swords 1781–1876)
* Gendaitō (modern swords 1876–1945)
* Shinsakutō (newly made swords 1953–present)

Heian to Muromachi periods

The was invented partway through the Heian period. With the beginning of the Kamakura period, were forged to be more aesthetically pleasing, and and became the most popular styles. Near the middle of the Kamakura period, more artisans were seen, increasing the abundance of the weapon, and the style became prevalent in the cities of Kyoto and Yamato. Because of the style introduced by the in the late Kamakura period, began to be forged longer and wider. The introduction of the Hachiman faith became visible in the carvings in the hilts around this time. The (line of temper) is similar to that of the , except for the absence of , which is and . and are found to have taken its place.

During the era of the Northern and Southern Courts, the were forged to be up to in length, as opposed to the normal one (about ) length. The blades became thinner between the and the , and wider between the and . At this point in time, two styles of 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 the average blade suffered greatly. As the end of the period neared, the average blade narrowed and the curvature shallowed.

Katana originate from , a kind of used by lower-ranking samurai who fought on foot in the Kamakura period. Their main weapon was a long , with the as a spare weapon. In the Nanboku-chō period, which corresponds to the early Muromachi period, long weapons such as were popular, and along with this, the lengthened, taking its form as the katana.''歴史人'' September 2020. p40.

Momoyama to the early Edo period

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 were invented, taking the place of the and as the most-used pair of weapons, and the number of forged was severely decreased.Satō (1983) p. 68 Since this period, have often been carved with splendid decorations. Of the and forged during this period, three masterpieces are called the .

Late Edo period

There were still a few being forged during the late Edo period, and the ones that were forged reflected the work of the Kamakura, Nambokucho, or Muromachi eras. Suishinshi Masahide was a main contributor towards the forging of during this age. There were now only predating the Edo period being used in combat; forged during the late Edo period were not combative weapons.

Meiji to present

Many were forged before World War II, due to the restoration of the Emperor to power. Members of the Imperial Court began wearing the set of and once more, and the number of in existence increased dramatically. After World War II, a restriction on sword forging caused manufacture to fall drastically.

remained in use among twentieth century yakuza (gangsters) since they could be carried as a concealed weapon more easily than a katana. A 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 outside Japan from the 1960s through the present time.

Types of

Blade types

*: A very common form with no , the edge bevels reaching all the way from the edge () to the back () with no separate flats in between, creating an almost triangular cross-section (the back is ridged, as on most other blade forms, so the cross-section is actually an extremely asymmetrical diamond shape; on blades it is hexagonal). It is extremely common due to the simplicity of its design.
*: This is the most common type of blade geometry for long swords, but made in this form are very rare, usually created from cut-down blades when a longer sword has been broken. means the central ridge that runs along the length of the blade between the edge bevels and the body of the blade.
*: feature an extremely long type point, over half the blade's length.
*: A common blade type that is very similar to the , except that it lacks a , the distinct angle between the long cutting edge and the point section, and instead the edge curves smoothly and uninterrupted into the point.
*: An uncommon style akin to the , with a back that grows abruptly thinner around the middle of the blade; however, the regains its thickness just before the point. There is normally a short, wide groove extending to the midway point on the blade.
*: These were shaped in the or style, but from about halfway to the tip the back edge was sharpened though this second edge was not particularly sharp. They had a groove running halfway up the blade and were similar to the -style .
*: A rare blade type with a double-edged point. Unlike the later the tip had a distinct shape unlike any other : the back edge would curve slightly downwards so that the point was lower than the back of the blade whereas other had the point in line with the back of the blade. Often they had a wide groove in the base half. The most well known historical blade of this type is the Kogarasu Maru, "Little Crow", one of the National Treasures of Japan.
*: A rare, double-edged type that has a diamond-shaped cross-section. The blade tapers to a point and contains a that runs to the point.
*: that have particularly thick cross-sections for armor-piercing duty.
*: An asymmetric form, sharpened only on one side to create a chisel-shaped cross-section.
*: A very rare type; the sharpened blade is on the inside curve rather than the outside. It has no sharpened point, making it difficult to use in battle and enshrouding the weapon in mystery. means . According to one myth, they were carried by attendants of samurai for cutting off the heads of fallen enemies. There are other speculations existing about the 's possible uses. Perhaps they were used by doctors or carried by high-ranking officials as a badge is worn today.

Mountings ()

*: The is a where the is flush with the mouth of the sheath. There is no handguard. normally have plain wooden hilts, and many forms of have that are made from animal horns.
*: The is a that features a small handguard.

Western Tanto

A popular style of blade, known simply as a Tanto in the US and Europe, is similar in style to the Tantō except that the tip is squared at a shearing angle instead of curved.

The shearing 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.

The Bundeswehr is among the few millitaries (if not the only) that issues a "tantō"-style military knife in significant numbers. It is designated as the KM2000.

*: This is also not truly a , though it is often used and thought of as one. were straight, double-edged blades often used for Buddhist rituals, and could be made from spearheads that were broken or cut shorter. They were often given as offerings from sword smiths when they visited a temple. The hilt of the may be found made with a ''vajra'' (double thunderbolt related to Buddhism).
*Modern : Modern tactical knives have been made by knife makers Bob Lum, Phill Hartsfield, Ernest Emerson, Allen Elishewitz, Bob Terzuola, Strider Knives, Harold J. "Kit" Carson, Benchmade, Camillus Cutlery Company, Spyderco, Severtech, Ka-Bar, SOG Knives, Columbia River Knife & Tool, and Cold Steel. These "American " designs which are often folding knives, feature a thick spine on the blade that goes from the tang to the tip for increased tip strength. The handle shape may be altered slightly to provide better ergonomics.
