Blade Hardness

HRC (Rockwell Hardness) measures how hard the blade's steel is. Kitchen knife steel typically falls in the high-50s to mid-60s on this scale. Harder steel is built to hold a fine edge over long use, while softer steel favors flexibility and easy resharpening. The right HRC depends on the steel and design, not a single higher-is-better number.

Stain Resistant

This steel resists rust and staining from moisture and acidic foods, making it easy to maintain with routine care.

Saya Cover

This knife comes with its saya cover included at no additional cost, shaped to its exact blade for the same custom fit customers pay extra for on other knives.

Product Details

Our Yoshihiro HAP40 High Speed Stainless Steel knives feature a hardened HAP40 powdered metallurgy core, heat treated to 66–68 HRC. The stainless-clad construction provides a balance of toughness, corrosion resistance, and ease of maintenance. Paired with an ocean blue handle and bolster, these knives are designed for professionals and serious home cooks who demand high cutting performance in a refined, practical package.

HAP40, developed by Hitachi, is highly sought after for its exceptional cutting ability, edge stability, and long-lasting sharpness. While extremely hard, it is easier to sharpen than ZDP-189 due to its lower chromium content. Its hardness delivers outstanding wear resistance and edge retention, though the lower chromium also means it can tarnish more easily if not cared for.

This combination of hardness, cutting performance, and manageable maintenance makes HAP40 a top choice for high-performance Japanese kitchen knives.
