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
Premium ebony with three inset rings gives this 8.25" (210mm) Hayate ZDP-189 Gyuto a formal, traditional handle. Its ZDP-189 core is hardened to about 65-67 HRC and clad in softer stainless, so it holds an extremely fine edge for a long time and rarely needs the stones.
With its very high carbon and chromium content, ZDP-189 combines extreme hardness with good corrosion resistance, allowing the edge to last far longer than most conventional kitchen knife steels. This level of performance greatly reduces the need for frequent sharpening, though the same hardness means ZDP-189 requires more skill and proper equipment if sharpening or edge repair is needed.
Due to its cost and demanding production process, ZDP-189 is typically reserved for top-tier knives and is most often used as a hardened core in laminated (San Mai) constructions. Cladding the core with softer stainless steel adds toughness and ease of maintenance while preserving the outstanding cutting performance and edge retention that define ZDP-189.
