The scabbard is well marked, with the maker and date “JEWELL – 1918” as well as  “H. E.” on the throat and “M. S.” on the bottom tip. The leather retains virtually all of the original surface and color, and the standard pistol belt brass attachment hook remains intact. The condition of this knife, which is over 100 years old, is very remarkable; it would be extremely hard to find a better example.



Historical Description: The first official U.S. trench knife adopted for service issue was the U.S. M1917 trench knife. It was designed by Henry Disston & Sons and based off examples of trench knives that were in service with the French Army at that time. The M1917 featured a triangular stiletto blade, wooden grip, metal knuckle guard, and a rounded pommel. The M1917 proved unsatisfactory in service, and a slightly improved version, the M1918, was adopted within months. Despite this, the M1918 is almost identical to the M1917, differing primarily in the construction and appearance of the knuckle guard. Usable only as stabbing weapons, the M1917 and M1918 frequently suffered broken blades. Their limited utility and general unpopularity caused the AEF to empanel a testing board in 1918, to test various trench knives and select a replacement.
