Hatsukokoro / Motokyuuichi Hamono "Kurosagi" Aogami Super 3-Layer Kurouchi 165mm Santoku

This "Shoshin" Kurosagi Nakiri 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 Nakiri 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

From the historic town of Shimabara, Motokyuuichi Hamono (本久一刃物) builds on a blade-making legacy stretching back to 1895. Inheriting the knowledge of esteemed swordsmiths, the Maeda family transitioned the craft to create exceptional kitchen knives. Today, the lineage is proudly continued by the father-and-son team of Kiyonori Maeda, the 4th generation master, and his son Yasuhide, the 5th generation. Central to their cherished method is the use of Shimabara’s pristine, volcanic-filtered water in the quenching process. They consider this unique water essential to their craft, allowing them to forge blades with their signature resilience and sharpness. Each knife embodies this multi-generational story, blending ancestral wisdom with the passion of its current masters.

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.
