It is very rare to see a tanto (small short sword) made during the Heian period. During the middle Kamakura period, a large number of wonderful tanto were made. They were called takenoko-zori shape. Takenoko means bamboo shoot. The back of the dagger curves inward slightly.
Sugata (shape)———-Hirazukuri , it means no shinogi, no yokote line, as you see in the illustration above. Standard tanto size is about 10 inches. The width is well balanced to the size of Tanto that means not too wide not too narrow. The Body is slightly thick. High Gyo-no-mune (行の棟) and Shin-no-mune (真の棟)
Hamon (刃文) —————- Tempered area is narrow. Nioi base. Irregular straight line (suguha midare) or straight line with small choji (suguha-choji). The tempered edge line may show a frayed look.
Boshi(tempered line at Kissaki area) ———Yakizume, Kaen, Niekuzure.
Engravings (彫刻 ) ———- Often different kinds of engravings are done at the lower part of the body of Tanto. These may be a groov or two grooves, Sanskrit, spear (Suken), dragon, etc,. For Sanskrit and spear, look at the illustration inside Chapter 9.
