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 and replica versions made of polystyrene foam or plastic are also available. Possession of this weapon is illegal in some countries, except for use in professional martial art schools.
双截棍或双节棍（日语：ヌンチャク 英文中通常为“nunchuks”，“chainsticks”，“chuka sticks” 或 “karate sticks”）是一种传统的中国武术武器，短链或绳索连接有两根棍子。 武器的两部分通常由木头制成，而链节则是绳索或金属链。
现代双节棍可以由金属，木材，塑料或玻璃纤维制成。 也提供由聚苯乙烯泡沫或塑料制成的玩具和复制品版本。 在某些国家/地区拥有该武器是非法的，但在专业武术学校中除外。
