Original U.S. WWI / WWII M1918 Mark I Modified Trench Knife with M1913 Patton Saber Blade by L. F. & C. with Custom Leather Scabbard

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 is an interesting WWII-era modified example of an M1918 Mark I Trench Knife hilt which has been fitted with a cut-down Model 1913 Cavalry Saber Patton Sword blade, now measuring 8” with a Bowie style. The ricasso is stamped L.F.&C. With a flaming bomb in the middle, over 1918 on one side, and U.S. over an eagle over No. 13. The blade retains some of its finish and has developed a lovely patina.

The brass grips are still partially darkened and are marked U.S. 1918 L.F & C - 1918. The crossguard has been cut down on both sides so it would fit better into the scabbard. The pommel nut was replaced by a now-smooth nut that appears to be sealed with lead. 

The custom leather scabbard is stitched, not riveted, with a thick belt loop and securing strap with a still-functional snap. There is minor verdigris but the leather is still strong. The scabbard with the belt loop is 11 ½”. The strap is precisely cut to wrap tightly around the grip through the middle finger hole. There is minor crazing and cracking in the strap, so use caution.

This is a great modified example of one of the most iconic knives ever used by the U.S. military. 

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.
