Hatsukokoro / Motokyuuichi Hamono "Kurosagi" Aogami Super 3-Layer Kurouchi 210mm Kiritsuke Gyuto

This Hatsukokoro "Kurosagi" Kiritsuke Gyuto is hand-forged with Aogami Super steel, heat-treated to 63-64 HRC. The Kurouchi-finished blade has a relatively rough fit and finish, but the beautiful tapering allows this knife to cut smoothly. It is a down to earth handcrafted Kiritsuke Gyuto that focuses on cutting performance above anything else. If you like a rough kurouchi finish that brings you back to the very basis of a great carbon steel handmade blade, this is the knife to go for.

About Motokyuuichi Hamono 本久一刃物

Care:

Aogami Super (Blue Super) steel is considered the most superior Japanese high carbon steel for knife making. Despite some corrosion resistant quality (for a carbon steel), it is not stainless, therefore you should wipe your knife dry after each use. Patina will develop over time. Rust may develop if left in prolonged contact with water or acidic food. Use a rust eraser to clean if rusts develop. Avoid cutting into bones, frozen foods, hard fruit pits.

Cutting Surface:

Recommended cutting surface: wood, rubberized boards and high-end composites, and quality plastics such as polyethene make acceptable cutting surfaces, and will help protect and prolong knife’s edge. AVOID glass, metal, countertops, and other rigid, non-forgiving surfaces.

Sharpening:

We recommend sharpening all quality Japanese knives on whetstones, as we believe they yield the best results for your knives.
