The V-42 Stiletto was a combat knife that was used by the United States and Canada during World War II. It was originally designed by Lt. Colonel Robert T. Fredrick for the joint Canadian-American Devil's Brigade.
The V-42 was commissioned designed by Lt. Colonel Robert T. Fredrick for use within his unit, the First Special Service Force, better known as the Devil's Brigade or Black Devils. The weapon was heavily inspired by the Fairburn-Sykes knife of Great Britain.
The knife featured a thumb-shaped imprint just above the leather handle, encouraging a flat grip that held the knife horizontally.
A pointed pommel was featured on the bottom of the knife for blunt attacks and, specifically, cracking skulls. The weapon's narrow profile ended in a sharp tip for thrusting. This tip could easily penetrate an M1 helmet and its liner in a single thrust.
Since the Devil's Brigade was originally purposed for winter conditions, the stiletto's sheath was exceptionally long with the knife itself towards the bottom. This was to keep the knife accessible from under a parka.
