The Handcrafted Nunchaku or nunchucks (Japanese: ヌンチャク nunchaku, often “nunchuks“, “chainsticks“, “chuka sticks” or “karate sticks” in English) 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, while the link is a cord or a metal chain.
The nunchaku is most widely used in martial arts such as Okinawan kobudō and karate, and is used as a training weapon, since it allows the development of quicker hand movements and improves posture. Modern-day nunchaku can be made from metal, wood, plastic or fiberglass. Toy versions and replicas not intended to be used as weapons may be made of polystyrene foam or plastic. Possession of this weapon is illegal in some countries, except for use in professional martial arts schools.
The origin of the nunchaku is unclear; a traditional explanation holds that it was originally used by Okinawan farmers as a flail for threshing rice. Another weapon, called the tabak-toyok, native to the northern Philippines, is constructed very similarly, suggesting that it and the nunchaku descended from the same instrument.
In modern times, the nunchaku was popularized by the actor and martial artist Bruce Lee and by Dan Inosanto. Lee famously used nunchaku in several scenes in the 1972 film Fist of Fury. When Tadashi Yamashita worked with Bruce Lee on the 1973 film Enter the Dragon, he enabled Lee to further explore the use of the nunchaku and other kobudo disciplines. The nunchaku is also the signature weapon of the cartoon character Michelangelo in the Teenage Mutant Ninja Turtles franchise.
In addition the nunchaku is used in certain contact sports.
