It is intended to be used as a training weapon, since practicing with it enables the development of quick hand movements and improves posture. Modern nunchaku may be made of metal, plastic, or fiberglass instead of the traditional wood. 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. One traditional explanation holds that it was originally invented by Emperor Taizu of Song, as a weapon utilised in war, initially named Grand Ancestor Coiling Dragon Staff (大小盤龍棍/太祖盤龍棍, taai3 zo2 pun4 lung4 gwan3/taai3 zo2 pun4 lung4 gwan3). 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.
