Nunchaku were traditionally wielded as a defensive weapon, used to lock joints and disarm weapons. Popular culture has shown nunchaku as a striking flail, which is how the weapon is often portrayed in TMNT media. They began as an ancient farming tool used to thrash grain.
- Broadcasts of characters wielding nunchaku were censored on UK television during the 1990s, often causing Michelangelo to either go bare-fisted during fights or wield alternative weapons. Eventually, this led to him using a new grappling-hook like weapon called the Turtle Line later on in the 1987 series.
