This 210 mm gyuto by Hatsukokoro pairs Ginsan (Silver Steel) with a visible undulating sanmai line along the edge, a mark of deliberate heat treatment. The curved blade profile suits both push-cut and rocking techniques, and the heel height provides comfortable knuckle clearance on the board. Kanji are engraved on the blade.
Ginsan, named Silver Steel for its high chromium content (13 to 14.5%), is a stainless steel whose sharpening behaviour closely resembles that of pure carbon steels. It reaches 59 to 62 HRC and responds quickly on whetstones, producing a very fine edge for a stainless alloy. The trade-off is a mild susceptibility to staining from highly acidic foods over time, with no risk of true rust under normal use. For cooks who want carbon-like responsiveness without the obligation of immediate drying, Ginsan offers a well-documented middle ground.
The octagonal wa-handle in dark brown wood with pronounced grain is separated from the blade by a light-coloured collar, creating a clean visual contrast. The octagonal section provides a secure grip across hand positions.
Care
Rinse and dry after each use. Do not wash in a dishwasher. No patina will form on this steel. Regular sharpening on water stones maintains the edge.
