Nunchaku is an instrument used to pound grain, which was later put to practical use as a weapon. The nunchaku was constructed of two hardwood sticks which were securely connected by rope braided from horses' tails. Today, the sticks are tied with rope or chain. Because of is innocent appearance, nunchucks could easily be mistaken for a toy or harmless bundle of sticks. In a defensive situation, however, it could be used to strike, block, hit, twist and pinch.
