- No
- Optional Magnolia Saya Cover
Blade Hardness
HRC (Rockwell Hardness) measures how hard the blade's steel is tempered. A higher rating holds a fine edge through extended use, a hallmark of Japanese blade craftsmanship.
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.
