Nunchaku are actually derived from a tool used to flail rice, so that the husks and any small sticks could be blown away by the wind.

The nunchaku is a very lethal weapon. When swung at speed, it can deliver hundreds of pounds of striking pressure. One strike to the head could kill or maim for life.

The nunchaku is a very capable tool for blocking/deflecting, ensnaring, choking and striking an opponent or would-be attacker.
