Here is a U.S. model 1917 Trench Knife made by American Cutlery Company displayed with a U.S. model 1917 Helmet. This item still retains much of its original finish. The grips have a few minor dings with no cracks. The 9” triangle blade has one noticeable ding that would be consistent with a defensive block and one small area of pitting on two sides of the blade. The First World War brought along many advancements in firearms and armour but with that being said often the taking of trenches involved brutal hand to hand combat. Very often soldiers would find the trench battle too tight of quarters to use their rifles and would switch to knives, clubs, shovels and anything else that would give them an edge in hand to hand combat. Buyer must be 18 or older and able to prove it. Shipping is available at buyers expense.
