Miki Deba Shirogami in 240mm (9.5") blade length is a heavy traditional Japanese knife for rougher tasks, intended for filleting fish and poultry. A proud member of the traditional Japanese trio (along with yanagiba and usuba knives). It is a large-sized deba designed for fish lovers and professional chefs. The blade thickness is at hefty 9.4mm (0.37"), the blade length is 240mm (9.5"), so it is suitable for filleting large-sized fish. Deba also performs well at smaller kitchen tasks, like mincing herbs or cleaning and preparing vegetables. The single bevel blade is suitable 🚨 for right-handed users only!

Miki Hamono uses the purest carbon steel available, produced by the Japanese steelmaker Hitachi. Shirogami steel #2 or “white steel 2” with a hardness of around 62-63 HRC, which is then forged welded with a second layer of softer steel. A two-layered blade construction, also known as ni-mai.

White steel can produce the highest level of sharpness and cutting ability from all Japanese steels, but it comes at a price. Very high maintenance is needed, rust resistance is very low so it will develop patina very fast, the blade has to be wiped dry after every use and oiled regularly to prevent rusting. Edge retention is a bit shorter than with some modern steels, especially compared to powder steels.

When you ask Japanese blacksmiths or sushi chefs why they all like white steel so much, you always get the identical answer: “Because it has a GREAT EDGE!”

»Great edge« in Japanese terminology translates as:

  • very high hardness and toughness (not being overly brittle)
  • very fine and homogeneous martensite steel structure (steel structure after heat treatment) which will after polishing produce a very fine/smooth edge
  • very easy to resharpen.

    🚩 Because Shirogami steel does not contain chromium, such a blade will develop some patina during use. The advantage of this steel, however, is that it has a very fine, gentle sharpness, is easy to sharpen and stays sharp for a very long time. Knife maintenance oil is recommended for the care of such blades.

    The blade is polished and hand engraved with the blacksmith’s signature. The transfer between jigane and hagane has a nice kasumi finish created by whetstones. The out-of-the-box sharpness is 7/10 because Japanese chefs like to put the final edge by themselves. If you prefer, we can sharpen it for you free of charge, just let us know when placing the order (leave a note in the cart).

    Handle is a simple traditional round Wa handle, made from magnolia wood. Magnolia wood is a soft, light-colored wood that needs some extra maintenance as it can stain easily, so we recommend having clean hands before using the knife. It is the preferred wood of Japanese sushi chefs due to its antiseptic properties and it is easy and cheap to rehandle as there is an abundance of magnolia handles on the market. The ferrule is made from water buffalo horn.

    About Miki Hamono:
    Miki Hamono is a small-scale blacksmith from the Miki area in Japan. Miki is a very famous blacksmithing area located in Hyogo prefecture in the center of Japan. They use an old Japanese forging technique that originated from making samurai swords (katanas). Miki Hamono is mostly known among Japanese sushi chefs for forging traditional single bevel shirogami (white) steel knives. Their knives are the perfect example of the Japanese traditional knives where every part of the knife is made the »right way«, like in the old days, but separates them from other similar blacksmiths by a very good price performance.

      ☝️ Japanese kitchen knives in our store are handmade from natural materials. Slight variations in color, texture, weight and other dimensions are possible. We try to give a good photographic representation of our products, however computer screen resolution and colors do vary, so products might not look exactly as they are seen on screen.


      Knives made of carbon steels can, due to their low chromium (Cr) content, discolor and develop patina. The knife is the most sensitive when it is still new and a patina had not developed yet, but later, patina will protect the blade. These types of knives require a touch more care:

      ✔ Wipe it regularly with a clean and dry cloth (you can also do this during use).
      ✔ After use, rinse it with lukewarm water and wipe it dry.
      ✔ Coat it regularly with knife maintenance oil or plain refined sunflower oil.
      ✔ Store the knife by wrapping it in paper which will absorb moisture and protect the blade.

      A patina is a thin layer that forms on the surface of oxidized steel and protects it from further oxidation. The patina should not be confused with rust. Patina protects the blade, while rust causes corrosion and deterioration of material, so it should be removed (see Rust erasers).

      → For in-depth information about patina, read our dedicated post on patina.


      Blade wear depends on the quality of steel, usage and maintenance of the blade. Japanese knives are made of high-quality steels. Follow these tips to keep your Japanese knife in top-notch shape:

      ✔ Use a wooden, plastic or rubber cutting board.
      ✔ After use, wash the knives and wipe them dry.
      ✔ For storage, use a knife holder or a protective knife sheath (saya).
      ✔ A good cutting technique is your best bet to prolong sharpness.
      ✔ Use sharpening stones to sharpen the knife.

      ❗️Don’t leave the knife in the sink. Wash it by hand.
      ❗️Don’t wash the knife in the dishwasher.
      ❗️Don’t use the knife on glass, ceramics, marble or steel surfaces.
      ❗️Don’t scrape the food off the cutting board with the edge of the blade. Use the spine of the knife instead.
      ❗️Knife is a tool intended for specific use - cutting food. It is not a can opener, screwdriver, trowel, wire cutter, hammer etc.
