WWI-Era U.S. Model 1917 Trench Knife – Heavy Spearpoint Blade with Turned Wood Grip

This is a fine example of a WWI-era U.S. Model 1917 trench knife, a brutal and utilitarian weapon issued to American troops during the First World War for close-quarters combat in the trenches of France. This particular knife measures 17 inches in overall length, with a broad 12-inch double-edged spearpoint blade that remains unsharpened on the spine but was clearly designed for piercing and thrusting. The blade exhibits uniform dark oxidation and minor pitting consistent with its age and battlefield intent. No visible manufacturer markings or ordnance stamps remain legible on the ricasso, suggesting this may be one of the less common contractor variants or a field-carried piece stripped of identifying marks through prolonged use.

The hilt consists of a turned cylindrical hardwood grip with a deep brown patina, flanked by a heavy circular steel guard and matching circular pommel base cap. Both elements exhibit surface oxidation and honest wear, with the pommel peened flat in classic period style. The grip has no cracks or breaks and retains its structural integrity, though it shows scattered surface darkening from oil and handling.

This knife’s sheer weight—approximately 1.5 pounds—combined with the thick, spear-shaped blade, reflects the brutal nature of trench warfare, where weapons like this were as much tools as they were instruments of war. The overall design is reminiscent of earlier Bowie and Arkansas toothpick forms, but tailored for mass production and extreme conditions. It should be noted this knife does not include a scabbard.

Historical Context:
The U.S. Model 1917 trench knife was one of several designs rushed into production during WWI to meet the demand for effective close-combat tools. This example, while not of the more common knuckleduster type like the LF&C Mark I, is indicative of early transitional designs adopted prior to more standardized models. Knives of this form may also have been manufactured in small numbers by local contractors or modified in-theater. They were popular among Doughboys for their rugged construction and simplicity.

Condition:

• Blade: Heavy spearpoint with age patina, oxidation, and edge darkening; no active rust

• Grip: Solid turned hardwood with even wear and darkened tone; no cracks or repairs

• Guard and Pommel: Original, both show patina and stable oxidation

• Overall: Good condition for age; displays well; no scabbard included
