M-9 Bayonet & Sheath | Black | USMC – Multi-purpose fixed blade knife

The M-9 Bayonet is a fixed blade knife originally designed for the US Marine Corps. This tactical knife features a 7Cr17MoV steel blade with satin finish and serrated spine. With its 33.35cm blade length and plain-edge cutting edge, it serves both as a bayonet and field utility knife.

Construction and materials

The knife measures 49.85cm in total length and weighs 779 grams. The blade is crafted from 7Cr17MoV stainless steel with a satin finish that reduces cutting resistance. The handle is made from TPU material, providing secure grip in wet conditions. A leather sheath is included for safe carrying and storage.

Application and use

Designed for military field operations, survival situations, and heavy-duty outdoor tasks. The plain-edge blade cuts through rope, webbing, and wood efficiently, while the serrated spine handles sawing tasks. The substantial blade length makes it suitable for clearing vegetation, food preparation, and emergency situations.

Integration and compatibility

As a fixed blade design, the knife requires no opening mechanism or locking system. The included leather sheath allows for belt carry or attachment to tactical gear. The bayonet lug compatibility varies by rifle platform – verify specific mounting requirements for military applications.

Maintenance and lifecycle

The 7Cr17MoV steel offers moderate corrosion resistance but benefits from regular oiling after exposure to moisture. Sharpen at approximately 20-degree angle using whetstones. The satin finish helps conceal minor scratches from field use.
