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. The knives were 11 ¾" in overall length, with a 6 ¾" dagger style blade. The brass grips were marked U.S. 1918 and with the maker's name or initials.

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. This example is missing the blued sheet steel scabbard, but still displays beautifully without it. This is one of the darker examples we’ve seen, still retaining most of its blackening.

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. This Mark I Trench Knife is clearly marked in two lines in the brass grip:

U. S. 1918
L. F & C - 1918

The brass grip and knuckle guard blackening is retained almost entirely. Where the blackening is worn there remains a lovely aged brass dark patina. The steel dagger blade still has much of the original factory grind visible with the finish retained very well, although there are spots where the blackening is worn from use.

Overall this is a very nice 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. Here’s a chance to pick one up without a scabbard to complete your set.
