It is very rare to see a Tanto (短刀dagger) made during the Heian period. During the middle Kamakura period, a large number of high-quality Tanto were made. They were called Takenoko-zori shaped Tanto. Takenoko means bamboo shoot. The back of the Tanto curves inward slightly.
Sugata (shape)———- Hirazukuri. It means there is no Shinogi, Yokote line. See the illustration above. The standard Tanto size is about 10 inches. The width is not too wide, not too narrow, very well-balanced size. The body is slightly thick. High Gyo-no-mune (行の棟) and Shin-no-mune (真の棟)
Hamon (刃文) —————-The tempered area is narrow. Nie base. Suguha-midare (straight line pattern with an irregular wavy pattern) or Suguha-choji (straight line pattern with small Choji). The tempered edge line may show a frayed look.
