Original Item: Only One Available. This is a very fine example of a French Made Au Lion 1918 Trench Knife with a Reproduction L.F&C marked steel scabbard. These are one of the most sought after military issue knives out there.

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. In order to save time in getting the new knife to troops in the field, the first Mark I trench knives were procured from a French manufacturer, Au Lion (Au Lion/Société Générale, France). 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 makers name or initials.

The U.S. Model 1918 Mark I Trench Knife offered here is in great service-used condition. The knife is one of the French made examples which is partially marked on the ricasso with a (Reclining Lion) / AU LION. The marking is on the reverse of the blade, so the blade may have been turned around at one point. The blade mark is about 20% retained, with only the right side of the lion visible. This brass grip of the knife is clearly marked: U. S. 1918. As is usually the case with the AU LION marked knives, the cast brass grip is rougher and cruder than the US made versions, with some residue as shown. As is also typical of the French made knives, the knuckle points are also less defined and not as sharp as the US made knives. The French made grips are cast with a variety of minor differences, and this one is cast with two grooves along the top edge of the grip. The brass knuckle grip has a lovely brass color with a heavy amount of patina, and spots of oxidation.

The blades of most of the AU LION knives were produced in the white, with no finish on the blade. The blade on this example has some rough wear, with a sizable chip in the blade on one side. The reproduction steel scabbard is in good condition and makes for a good display with this original knife.

Overall this is a fine example of the very popular and collectible World War I era US trench knife. The knife is 100% original and the scabbard is reproduction, and would make a fantastic addition to any military edged weapons collection. 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.
