Minonokuni Gin-San 9.4-inch (240mm) Mioroshi Deba

The 240mm mioroshi deba is a long fish knife for large fish. Its length lets the cook follow the backbone of a big salmon or yellowtail in long strokes, and its slimmer blade can then portion the fillets without switching knives.

Compared with a standard deba of similar length, the mioroshi is narrower and lighter at the tip. It still handles the head and collar of large fish through the heel, but it is not a cleaver. Avoid heavy bones and frozen fish.


The Case for Gin-san

Gin-san silver steel is stainless, so a long blade that spends hours around water stays free of rust with ordinary drying, and it sharpens with a feel close to carbon steel. It is a specialty line, technically more premium than our standard lines, but not necessarily the right choice for every cook.

The shorter Gin-San 195mm mioroshi deba is easier to handle on medium fish. For slicing sashimi from the fillets, pair it with the Gin-San 240mm yanagi. See the knife shapes guide for the deba and yanagi.

About a Hand-Forged Knife

Each Gin-san knife is hammer-forged by hand rather than stamped or cut by machine. Forging marks, slight unevenness in the kasumi finish and small differences between one knife and the next are part of that work, and they do not affect the edge.


Before First Use

Wash the blade in warm, soapy water and dry it thoroughly. The knife arrives sharp, and a few strokes on a fine waterstone will refine the edge to the cook’s preference.


Tips for Best Results

  • Fillet with long strokes along the backbone, keeping the blade flat to the frame.
  • Use the heel for heads and collars on medium fish only; it is not a cleaver for heavy bone.
  • Sharpen the beveled face on waterstones and take off the burr with light strokes on the back.
  • Cut on wood or a soft synthetic board.

Care

  • Hand wash and dry the knife after use. Do not put it in a dishwasher or leave it to soak.
  • Gin-san is a stainless steel and resists rust, but drying the blade keeps the edge and the wooden handle in good condition.
  • Store the knife in a block or on a magnetic strip so the edge does not touch other utensils.
