BENCHMADE: H20 Fixed Dive Knife

Originally developed for an elite military program, the H2O Fixed Dive Knife is a purpose-built underwater utility blade engineered for reliability in harsh marine environments. Compact, lightweight, and corrosion resistant, it delivers dependable performance for diving, rescue, and maritime operations.

The N680 stainless steel blade offers excellent corrosion resistance and durability, enhanced by a protective Cerakote® finish. Featuring an opposing bevel grind, partially serrated edge, blunt prying tip, and integrated rescue hook, this fixed blade is equipped to handle cutting, prying, and emergency tasks underwater or on deck.

A Santoprene® handle provides a secure, non-slip grip—even when wet or gloved—while the molded thermoplastic sheath with thumb release ensures safe, fast access when seconds matter.
