In a number of countries, possession of nunchaku is
legally restricted, ranging from prohibiting carrying them concealed in public to outright banning any form of possession. Nearly all such regulations were created in the 1970s after a wave of popularity attributed to their appearance in the Bruce Lee martial arts films and related media. This popularity led to them being commonly found in the possession of delinquent youths and petty criminals. This combination of popular media exposure creating the impression of danger and lethality, and their perceived popularity with undesirable classes of society, led to legal restrictions being passed. Later legal challenges led to closer examination of nunchaku's actual use in criminal behavior, and have found that most of these laws were likely not warranted. In Australia, a state or territory approval in a B709B form is required to lawfully import any nunchaku made of hard materials. They are classified as prohibited weapons in
New South Wales. Norway, Canada, Russia,
Poland, and Spain are all known to have significant restrictions. In Germany, nunchaku have been illegal since April 2006, when they were declared a strangling weapon. In England and Wales, public possession of nunchaku is heavily restricted by the
Prevention of Crime Act 1953 and the
Criminal Justice Act 1988. However, nunchaku are not included in the list of weapons whose sale and manufacture is prohibited by
Schedule 1 of the Criminal Justice Act 1988 (Offensive Weapons) Order 1988 and are traded openly (subject to age restrictions). In Scotland, laws restricting offensive weapons are similar to those of England and Wales. However, in a case in 2010,
Glasgow Sheriff Court refused to accept a defence submission that nunchaku were not explicitly prohibited weapons under Scottish law, although the defendants were acquitted on other grounds. The UK version of
ThunderCats edited out nunchaku used by the character
Panthro.
Teenage Mutant Ninja Turtles needed to be edited, the nunchaku used by
Michelangelo were edited, until they were replaced by a
grappling hook. The UK version of the video game
Soul Blade was also edited, replacing the character
Li Long's nunchaku with a three-sectioned staff. In Hong Kong, it is illegal to possess metal or wooden nunchaku connected by a chain, though one can obtain a license from the police as a martial arts instructor, and rubber nunchaku are still allowed. Possession of nunchaku in mainland China is legal. In the United States, regulations on nunchaku vary by state as well as county and city jurisdictions. Some states do not apply any restrictions, while other state laws and local ordinances continue to prohibit carrying nunchaku in specific situations, such as on school grounds or in government facilities, or if carrying in public as a concealed weapon. Broader prohibitions were passed in the 1970s for the reasons outlined above, but many have since been repealed or overturned. State-level nunchaku bans on possession were initially passed in New York, Arizona, California, and Massachusetts, but only the Massachusetts ban remains: == Law enforcement use ==
