The Matayoshi Kobudo system places great emphasis on the use of the bo, an implement said to be derived from the tenbib, which was a wooden staff that was slung across the shoulders in order to transport buckets of water on each end. The most popular type of bo is the rokushaku, which measures six feet in length and 1 1/4 inches thick at the center, tapering down to 3/4 inch at the ends.
