High-Carbon Care

No
Optional Magnolia Saya Cover

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 is not stain resistant. High-carbon steel can rust or develop a patina if not kept dry and cared for, in exchange for the sharper edge it holds.

Saya Cover

This knife does not automatically come with a saya cover included. Adding one with your order lets us shape it to this exact blade, a fit no aftermarket cover can match. A saya purchased separately later is cut to standard dimensions rather than this specific blade, so the fit is left to chance.
