Tekken

Tekken were Rokugani metal knuckles held in the hand or worn with one's fingers slotted through its holes. They were easily concealed, and delivered a little extra weight and cutting power to a simple strike. They came in various forms, the simplest of which is a hollow semicircle gripped like a handle. Others had individual slots for fingers or were simply rings with spiked protrusions on one side to cause pain, distraction, and bleeding.
