I trench knife is an American trench knife designed by officers of
the American Expeditionary Force (AEF) for use in World War I.
It has 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
The blade of this knife
is the full 6.75 inch and has the correct conical steel nut. The handle retains
its original design. The scabbard is a reproduction. However, it is a high-quality
reproduction from International Military Antiques (IMA) and nicely compliments
