Mark I Knife

The KA-BAR Mark I Kraton G® (2221) is a modern remake of the highly sought-after knife originally issued to the U.S. Navy during World War II. Known for its compact size and versatile utility, the Mark I earned a reputation as a trusted companion aboard ship and ashore. This updated version preserves the legendary design while enhancing it with today’s most durable materials and finishes.

Historic Design, Modern Materials

The 5.125” blade is crafted from high-carbon steel and finished with a non-reflective black epoxy powder coating, proven through rigorous testing to be tougher than ever. The tang is proudly stamped “USN,” honoring its wartime heritage. Retaining the iconic oval handle shape, this version is upgraded with Kraton G®—a synthetic material nearly impervious to sweat, water, chemicals, and wear—providing unmatched grip and durability in any condition.

Sheath and Carry Options

Each Mark I Kraton G® comes equipped with a MOLLE-compatible hard plastic sheath, offering secure protection and multiple mounting options on belts, vests, or packs. Compact, rugged, and deeply rooted in naval history, the KA-BAR Mark I Kraton G® is an ideal choice for collectors, outdoorsmen, and anyone seeking a proven utility blade with modern resilience.
