Sasumata
The sasumata (刺股; spear fork) is a polearm, a "man catcher", used by the samurai class and their retainers in feudal Japan. == Etymology == The term sasumata combines the Japanese words 刺 (sasu, "to stab" or "to thrust") and 股 (mata, "fork" or "crotch"), literally meaning "thrusting fork." The name highlights its dual nature: a polearm-like implement but primarily designed to restrain or pin a suspect against the ground or wall.
