Description

The Nakamura Hamono Kurouchi Deba Knife 210mm is a handcrafted Japanese kitchen knife by Nakamura Hamono, a 120-year smithy in Oita, Japan. This double-bevel knife is made from Aogami No. 2 steel and soft iron using the traditional hon-warikomi technique. It features a poplar wood handle and is engraved with the signature of the smithy.

About the Blade Shape: A traditional Japanese fish butchery knife, deba knives are built for breaking down whole fish with power and control. The thick spine and substantial weight provide strength for cutting through heads and bones, while the sharp double-bevel edge allows for precise filleting work. Although traditionally designed for fish preparation, they are also suitable for cutting poultry and other meats with small bones as well.

      Product Care Instructions

      HOW TO USE?

      • Only cut food you can bite and chew with this knife since hard foods can chip the blade. Do not cut olive pits, bones, lobster shells, wood pieces or frozen food, which are especially bad  due to the cold making hard steel more brittle.
      • Do not use the knife in twisting motions.
      • Use wood or plastic cutting boards to avoid dull knives. Do not use glass,  granite or bamboo surfaces.

      HOW TO CLEAN?

      • After each use, hand wash the knife with mild detergent and a soft sponge, rinse with hot water and dry by hand immediately. Do not use the dishwasher.
      • Wood handles may dry out over time and exposure to water. To prevent this, use some food safe mineral oil or beeswax.  

      HOW TO SHARPEN?

      • Use the FREE WHETSONE included with the knife for sharpening. It is recommended by the manufacturer.
      • Remember to sharpen both sides evenly as this is a double-bevel knife.

      HOW TO STORE?

      • Wrap the blade in newspaper to reduce direct exposure to the air and prevent rusting if you keep knives in a drawer or travel case. 
      • If you are hanging the knife or using a knife stand, remember that the blade should point downwards.
      • If you are storing them in a drawer, keep the edge from touching anything else.
