⚔️ In the mud, blood, and horror of World War I’s trenches, rifles jammed, grenades misfired… but one weapon never failed: the American M1917 and M1918 Trench Knives.

Designed for close-quarters combat in the claustrophobic nightmare of trench warfare, this knuckle-duster dagger became the most feared hand-to-hand weapon of the American Expeditionary Forces — and for good reason.

In this deep dive, you’ll discover:
✅ Why it combined brass knuckles + a 7-inch dagger — to smash faces and stab hearts in one brutal motion
✅ How it was born from brutal French and British trench raids — and improved upon their designs
✅ The terrifying psychology behind its cast-iron knuckle grip — meant to break jaws before the blade even struck
✅ Real accounts from U.S. “Doughboys” who used it in night raids on the Western Front
✅ Why German soldiers feared American trench raiders — and called them “devils with knives”
✅ How it influenced modern combat knives like the KA-BAR and Marine Corps fighting knife

This wasn’t just a tool.
It was silent, personal, and merciless — the perfect weapon for a war that had no mercy.
