The smatchet was a heavy-bladed fighting knife designed by William Ewart Fairbairn. Fairbairn instructed British Commandos, the Special Operations Executive and the American Office of Strategic Services on close combat techniques. He based his teaching, and the weapons he designed, on experience gained while serving with the Shanghai Municipal Police. The smatchet’s leaf-shaped blade enabled it to be used for slashing, thrusting or chopping at an opponent. The heavy pommel could be used to deliver a smashing blow. Fairbairn wrote that, “the psychological reaction of any man, when he first takes the smatchet in his hand, is the full justification for its recommendation as a fighting weapon.” No record exists of the Smatchet’s use in combat.
