KA-BAR Mark 1 Navy Fighting Knife Fixed Blade 5.13in Black Blade KA2221

During the height of World War II, the U.S. Navy needed a dependable, compact knife to serve sailors in the harshest conditions at sea and in combat. The Mark 1 Navy Fighting Knife was born out of that need—a versatile tool trusted for everything from slicing through heavy rope to hand-to-hand combat in confined quarters. KA-BAR, already a trusted name among American service members, was one of the original military contractors chosen to produce the Mark 1. Today’s version carries the same spirit of resilience, function, and history, with updated materials that make it ideal for modern users.

The KA-BAR Mark 1 Navy Fighting Fixed Blade Knife features a 5.13-inch clip point blade crafted from 1095 Cro-Van steel, a rugged carbon alloy known for its edge retention and toughness. The black epoxy powder-coated finish enhances corrosion resistance and reduces glare, perfect for tactical or outdoor environments. A flat grind ensures a razor-sharp edge capable of tackling utility and combat tasks with ease.

A hallmark of the Mark 1 design is its stacked leather handle, offering both heritage aesthetics and practical performance. It provides a secure grip even when wet, giving users confidence whether they’re on deck or deep in the woods. The handle is paired with a black powder-coated carbon steel guard and butt cap for added durability and balance. A subtle “USN” tang stamp pays tribute to the knife’s naval heritage, making it a favorite among collectors, veterans, and serious outdoorsmen alike.

This full-tang fixed blade comes with a MOLLE-compatible hard plastic sheath. It’s built for secure retention and quick deployment, with multiple attachment options for packs, belts, and tactical vests. Weighing just 8 ounces and measuring 9.19 inches overall, the Mark 1 is compact enough for everyday field carry but tough enough for the most demanding situations.

Proudly made in the USA, the KA-BAR Mark 1 Navy Fighting Knife is more than a cutting tool—it’s a piece of living history engineered for today’s challenges.
