Original Item: Only One Available. The U.S. Model 1918 Mark I Trench Knife 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. The knife was manufactured in the United States by Henry Disston & Sons (H.D. & S.) as well as Landers, Frary & Clark (L.F. & C.) and Oneida Community Ltd (O.C.L.). The knives were also produced in France and are marked with the usual 1918 and US marks, as well as Au Lion on the blade. Whether this mark was a maker's mark or simply a motto is not known.

The U.S. M-1918 Mark I Trench Knife is easily identifiable due to its large "brass knuckle" style guard and grip. This knife is 11 ¾" in overall length, with a 6 ¾" dagger style blade. The overall length with scabbard is 12”. The brass grips are beautifully darkened and are marked U.S. 1918 / L.F & C - 1918. The scabbard is marked LF&C 1918. The scabbard has been modified, likely during the World War II period, for wear on a standard belt. It does not fit on an M1912 Pistol belt, so we aren’t sure what belt it was meant to fit. Perhaps it was captured by a German who modified the scabbard to fit on his belt. 

As originally issued, the knives were entirely blackened; both the blades and the brass knuckle hilts. These knives remained in use with the US military, classified as limited standard (secondary issue) through January of 1945, when the knives were officially classified as obsolete. As originally issued, the knives were carried in a blued sheet steel scabbard that was typically maker marked, and was equipped with a pair of wire tabs that were intended to engage the US pistol web belt in use at that time. Many of the knives issued during World War II ended up in substitute leather scabbards of various designs and styles, many of which were "theater made".

The knife was produced by the Landers, Frary & Clark company of New Britain, CT. L.F. & C. was established in 1865 and produced a wide variety of housewares, cutlery and event appliances. Many of their products were marketed under the trade name "Universal". The products of L.F. & C. included everything from scales, mousetraps and ice skates to electric ranges and toasters. L.F. & C. also produced the triangular blade US M-1917 Trench Knife as well. The assets of the L.F. & C. company were purchased by General Electric in 1965.

The brass grip and knuckle guard blackening is partially retained with a lovely patina. The steel dagger blade appears to have been refinished during the period with heavy sharpening marks over this. Overall this is a fair refinished example of the very popular and collectible World War I era US trench knife. These brass D guard knuckle knives always make a great centerpiece to any military knife display and certainly draw attention due to their size and fierce appearance.
