Chapter 13 Kamakura Period Tanto described that the shape of a tanto is called Takenoko-zori appeared during the middle Kamakura period. This style of tanto curves inward a little at the tip. The drawing below may be a little exaggerated to show the curve. The real Takenoko-zori curve is not so obvious. Maybe a few millimeters inward. Usually, the length of the Tanto is approximately 12 inches or less. Tantos are described as follows; a tanto of approx. 10 inches is called Jyosun tanto (定寸短刀), longer than 10 inches is Sun-nobi tanto (寸延び短刀 ), and less than 10 inches is called Sun-zumari tanto (寸詰短刀).
