The hanbō (半棒, lit. "half-staff") is a staff used in martial arts. Traditionally, the hanbō was approximately three shaku or about 90 centimetres (35in) long, half the length of the usual staff, the ****** ("six shaku staff"). Diameter was 2.4 to 3 centimetres (0.94 to 1.18in). However, depending on the school the length and diameter varied.
