Do a Licence is required for purchasing Nunchaku and using the Martial arts weapon for Self defence purposes as well as by Bodyguards?
Good question. I found this online:
In a number of countries, possession of nunchaku is illegal, or the nunchaku is defined as a regulated weapon. Norway, Canada, Russia, Poland, Chile, 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 list of weapons whose sale and manufacture 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 is similar to that of England and Wales. However in 2010 Glasgow Sheriff Court refused to accept a defence submission that nunchaku where not prohibited weapons under Scottish law although the defendants were acquitted on other grounds[31].
The use of nunchaku was, in the 1990s, censored from UK rebroadcasts of American children's TV shows such as Teenage Mutant Ninja Turtles cartoons and films. The UK version of the Soul Blade video game 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.
Legality in the United States varies at the state level. As elsewhere, the popularity of Bruce Lee movies in the 1970s led to a wave of nunchaku bans. Many states prohibit carrying nunchaku in public as a concealed weapon, but a small number restrict or completely ban ownership.
