The nunchaku consists of two sticks connected by a short chain. The sticks are usually wooden or metal, although rubber and plastic ones also exist.
The nunchaku is a bludgeoning weapon that uses the momentum from a swing to increase the impact. However, tests have shown that some of the impact is absorbed by the weapon’s flexibility. The weapon also requires a good deal of training to be effective in a fight. Many believe that the nunchaku was originally used in ancient China as a farming tool before being adapted in Okinawa to be used in battle.
