About Yoshikane Hamono

To date, they have kept going in the traditional way with such focus and dedication that can only be found in this part of the world.
Shirogami #2 (white #2) steel is one of the most popular steel type found in Japanese kitchen knives (Wa Knives). It is not stainless steel, therefore you must wipe your knife dry after each use, in particular the core steel not covered by the stainless cladding. Patina will develop over time, which will appear as “discoloration” on cutting edge, but that is the nature of carbon steel - not a defect. The stainless cladding covers a large part of the blade, making maintenance easier but still preserve the cutting and sharpening pleasure of the Shirogami core. Avoid cutting into bones, frozen foods, hard fruit pits.
Cutting Surface: Wood, rubberized boards and high-end composites, and quality plastics such as polyethylene 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.
