Composition

Core alloying elements define the baseline trade-off between wear resistance, corrosion behavior, and toughness.

Material Overview

H2 steel is a Japanese stainless steel specifically engineered for maximum corrosion resistance in harsh and saltwater environments. It contains very low carbon and high chromium content, prioritizing rust resistance and toughness over extreme hardness or edge retention. H2 is commonly used in diving and fishing knives where exposure to moisture and saltwater is constant. Its soft composition also makes sharpening quick and simple, making it practical for field maintenance.
