noun
sasumata; man catcher; two-pronged polearm

捕具 is a general term for traditional Japanese arresting implements, while さすまた refers specifically to the two-pronged man catcher.
The word さすまた is composed of 刺す (sasu, 'to pierce' or 'to thrust') and 股 (mata, 'fork' or 'crotch'), referring to the forked shape of the weapon. The exact historical derivation is uncertain.
