The U.S. Model 1918 Trench Knife Short Sword was the second major “Knuckle Knife” to be officially adopted and issued to the US military. It was developed for use in the horrific trench warfare that typified the stalemate on the Western Front during the latter part of World War One and saw use not only there, but during World War Two as well. A modern reproduction of the famous US 1918 Military Brass Short Trench Sword from World War One but with traditional double edge blade.
