The Nunchaku (ヌンチャク) or sosetsukon is the most famous Kobudo weapon. It has been popularised by Bruce Lee movies in the 80s.
Nunchaku is a derivative of threshing flail or aderivative of horse’s bit. It is made by 2 red oak sections connected by a cord. The sections can be octogonal (Okinawa) or rounded (China).
The cord between the two sections is placed using a very specific node called Okinawan node.
This weapon is very dangerous to be used (some practitioners are using an helmet during the first sessions).
Nunchaku is reserved for well experienced kobudoka and is required for Black Belt testing (Shodan).
