A shobo is a weapon similar to the Emei piercer of China which was used by the ninja of Japan for striking pressure points on an opponent. It was a piece of wood that was gripped by the wielder and was hung by a ring worn on the middle finger. Some versions were rings with a wooden peg attached on top. The ends were exposed and were usually sharp which made them effective for paralyzing and even killing enemies quickly and without leaving a trace.
