Stainless-Clad Care

This knife is made with stainless cladding over a high-carbon core. The cladding resists rust, but the exposed core at the edge can still discolor or rust if not kept dry and properly maintained.

63 HRC
Yes, except along the knife's edge
Free Magnolia Saya Cover Included

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 knife's cladding resists stains, though the exposed high-carbon edge can still discolor or rust without regular 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 Kurouchi Stainless Clad Knives exemplify the perfect marriage of traditional craftsmanship and modern metallurgy. Featuring a Kurouchi finish on stainless cladding, these knives maintain the rustic aesthetic of a "Black-Forged" blade without the upkeep challenges of high-carbon steel. The stainless cladding not only enhances durability but also protects against moisture while preserving the sharpness and strength of the blade. At their core, the knives are crafted with Blue Steel #2, a premium high-carbon steel with a hardness of 63 on the Rockwell scale, celebrated for its exceptional edge retention and sharpness that withstands prolonged use.

This 180mm Santoku brings the format to the Hayate Hinoura line: a shorter, wider all-purpose blade with a gently curved tip, built for the classic three-way santoku work of slicing, dicing, and mincing in everyday prep.

Each knife is complemented by a handcrafted Octagonal Stabilized Maple Burl handle with water buffalo horn bolster (color varies), designed for comfort and usability for both left- and right-handed users. To enhance the knife's protection and aesthetics, it comes with a Magnolia wood Saya Cover, providing easy and safe storage. Whether you're dicing fresh produce from a farmer's market or carving a roast chicken from the oven, even the simplest culinary tasks are elevated with a handcrafted knife that seamlessly combines beauty and functionality.

The knife features a stainless steel cladding that ensures durability and resistance to corrosion while retaining a sharp edge. The Blue Steel core is renowned for its exceptional sharpness and edge retention, making it ideal for professional chefs who demand precision in their cuts. However, while most of the blade is stainless steel, the exposed Blue Steel edge may rust if not properly cared for. It is recommended that chefs regularly dry and oil the blade after use to prevent oxidation.

Elevate your culinary experience with the Yoshihiro Kurouchi Stainless Clad Knives, complemented perfectly by the Custom-Cut Saya Knife Cover—where traditional craftsmanship meets modern innovation for a knife that is both exquisite and practical.
