A bokken is a
wooden sword usually used for sword training. When a student begins to work with a sword, he learns basic maneuvers with a bokken. However, the bokken can also be used as an
effective weapon since it is made of strong, heavy wood. In fact, many Ninja preferred to use the bokken
on a mission than a regular sword.
The reasons for this are that a bokken is lighter and easier to carry, there is no risk of cutting oneself, bokken are very easy to
camouflage since they can be stained or painted, and, when using proper
techniques, a bokken can easily break bones and damage
internal organs.
