Japanese tantō
The tantō is commonly referred to as a knife or dagger. The blade is single or double edged with a length between 15 and 30 cm (6-12 inches, in Japanese 1 shaku). The tantō was designed primarily as a stabbing weapon, but the edge can be used for slashing as well. Tantō are generally forged in hira-zukuri style (without ridgeline), meaning that their sides have no ridge line and are nearly flat, unlike the shinogi-zukuri structure of a katana. Some tantō have particularly thick cross-sections for armor-piercing duty, and are called yoroi toshi. Tantō were mostly carried by samurai, as commoners did not generally wear them. Women sometimes carried a small tantō called a kaiken in their obi primarily for self-defense. Tantō were sometimes worn as the shōtō 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 the tachi would be paired with a tantō and later the uchigatana would be paired with another shorter uchigatana.
