The classic knuckle duster knife — never leave the trench without it. The first trench knife officially adopted by the U.S. military was the U.S. M1917 during the First World War. These blades were designed to handle close combat situations that soldiers often encounter in trenches. This patriotic t-shirt pays homage to the original “plan B’ weapon.
