The U.S. Marine Raider Stiletto was a stiletto issued to the Marine Raiders and 1st Canadian Parachute Battalion during World War II.At the start of World War II, the Mark I Trench Knife was the only knife issued to Marines. It was introduced during World War I for trench warfare, but its "knuckle duster" hilt was cumbersome and contained nearly 1 pound (0.45 kg) of brass, making the knife expensive to produce. In addition, the Mark I could not be held in the "fencing-grip" position, the preferred position for the thrust. The Marine Corps began issuing the KA-BAR, a combination fighting/utility knife, in 1942 due to the inadequacies of the Mark I. The Marine Raiders, however, desired a dagger designed solely for knife fighting, but none were available that met the requirements.
