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. 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".

This example of the U.S. Model 1918 MkI Trench Knife is offered in good condition.

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 little. Where the blackening is worn is a lovely aged brass dark patina. The steel dagger blade still has much of the original factory grind on the edge, and has little of the original factory finish. There is past pitting present on the blade as well as areas of staining.

The steel scabbard is in good condition, though is missing nearly all of the blackening and both of the belt prongs. The scabbard is clearly marked on the rear, near the throat:

L. F. & C.
1918

The sturdy steel scabbard is securely nestled within a weathered leather belt scabbard, which appears to have been crafted with great care and attention to detail. A single rivet has been firmly fixed through the bottom of the leather, passing through the steel, to ensure that the scabbard stays in place and cannot be dislodged easily. The leather scabbard bears the marks of frequent use and wear, indicating that it has seen many years of service. It is highly likely that this scabbard was created during WWII, a time when these knives were widely used by Paratroopers, who held them in high esteem for their reliability and functionality.

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.
