The nunchaku is a traditional Okinawan martial arts weapon consisting of two sticks connected at one end by a short chain or rope.

The two sections of the weapon are commonly made out of wood, foam or plastic while the link is a cord or a metal chain. The nunchaku is most widely used in martial arts such as Okinawan Kobudo and karate, and is used as a training weapon because it allows the development of quicker hand movements and improves posture.
