Metal
History:
Used for easing the handling of horses harnessed to carriages.
Traditional use:
Developed from various sources depending on the type used. The tekko/metal knuckle-duster was used from the stirrups of a horse while the wooden tecchu is said to have come from the Okinawan fisherman. The fisherman used this instrument to assist with hauling their nets in order so that the coral would not tear the skin of their hands.
Current use:
Mainly used by high level Kobudo practitioners and is not very often seen. Training with the Tekko develops upper body strength, and quickness.
