Nunchaku is the MOST effective blunt force trauma type weapon. when folded up it is easily concealed in a coat pocket, in the small of your back, etc. yet when fully extended during a strike it is the same length as a full sized baton. the striking end of the nunchaku travels much faster than the striking end of a baton because it has to travel a larger distance in the same amount of time during a swing, much like a whip, making the nunchaku a much more devastating weapon. national geographics fight science did analyze the effectiveness of the nunchaku but their test is are VERY misguided and VERY misleading. they tested the weapon on a target that was made of rubber and bolted down. this target that was used to test the weapon doesnt move and doesnt give. the rubber target DEFLECTS all the energy causing the end of the nunchaku to rebound on the user. flesh and bone, on the other hand, ABSORBS the energy. if you smash an opponent over the head with nunchaku, it WILL NOT REBOUND. instead, the opponents flesh and bone WILL GIVE, will break, massive trauma!! it is not designed to strike wood, metal, rubber, concrete, etc. it is meant to be swung through your opponent smashing bone and causing massive trauma. it is not a dueling weapon. it is primarily an offensive weapon. the trained user is always changing positions and incorporates a series of feints and constant movement to beguile the opponent and find an opening to strike. in the hands of a trained user the nunchaku is the most devastating blunt force trauma type weapon.
