The Nunchaku (Japanese: ヌンチャク Hepburn: nunchaku?, often “nunchuks” or “chainsticks” in English) is a traditional Okinawan weapon consisting of two sticks connected at one end by a short chain or rope. It was used by Okinawan nobles rather than rebelling peasants, but was not a popular weapon since it was not efficient against the most widely used weapons of that time, and few techniques for its use exist. The two sections of the weapon are commonly made out of wood, while the link is a cord or sometimes a metal chain. The nunchaku is most widely used in martial arts such as Okinawan kobudō and karate, and makes for a good training weapon, since it allows for developing quicker hand movements and improves posture. Many varieties of nunchaku are available.
In modern times, nunchakus (Tabak-Toyok) were popularized by Bruce Lee and Dan Inosanto in their respective movies. Organizations like The North American Nunchaku Association, World Amateur Nunchaku Organization, Fédération Internationale de Nunchaku de Combat et Artistique, World Nunchaku Association and International Techdo Nunchaku Association teach the use of it as a contact sport.
Modern day nunchaku can be made from metal, plastic or fibreglass. In addition, toy and replica versions are available, made of styrofoam or plastic. Except for use in professional martial art schools, possession of this weapon is illegal in some countries.
