Walking stick
The walking stick is a weapon in martial arts. Both stick training and shinai (sword) training use the walking stick. Some are light but shinai-weight and heavier are more common. It can be less lethal than a sword but is deadly against a knife or similar weapons. With practice a walking stick user can deliver a kote-man or double-strike. Once to the wrist (holding the knife) followed instantly by a second blow to the assailant's head. The walking stick has the added advantage it does not look like a weapon. It looks fairly harmless.
