Blade is in overall good shape with slight damage to distal blade (in photo). The Scabbard is missing its prongs for the belt. Try to find a better price for an Authentic Mark I in this condition. Belonged to an avid WWI/WWII collector. One of the first Knives of US Special Operations the Rangers and the Marine Raiders the fathers of Marine Recon.

The Mark I trench knife was an American trench knife designed by officers of the American Expeditionary Force (AEF) for use in World War I. It had a 6.75 in (17.1 cm) double edged dagger blade useful for both thrusting and slashing strokes, unlike previous U.S. trench knives such as the M1917 and M1918. The handle is made of cast bronze and uses a conical steel nut to hold the blade in place. The Mark I's blade was blued with a black oxide finish, the bronze handle was chemically blackened, with cast spikes on the bow of each knuckle. The spikes were intended to prevent an opponent from grabbing the knife hand, as well as to provide a more concentrated striking surface when employed in hand-to-hand combat

Of those Mark I knives released for service, most were issued in 1942 and 1943 to soldiers serving in elite Army Ranger and airborne formations, though some Mark I knives were used by Marine units in 1942 and 1943, in particular marines serving with the four Marine Raider battalions.
