Undoubtedly one of the most powerful deba knives in our collection, the Kurokaze Ryo-Deba Aogami #2 Kuro-uchi 150mm is crafted for dedicated fish enthusiasts (and chefs!) with a bit of arm strength. 

This deba stands out from most other (typically single-bevel) deba knives with its double bevel edge, meaning this deba is a Ryo-Deba knife. This means easier sharpening, but also makes it ideal for heavy-duty tasks such as cutting through bones of large fish and chicken. Due to its symmetrical blade, it is suitable for both right- and left-handed users. It is designed for heavy-duty work of skilled professionals, or experienced home users. It is especially recommended for "big game" fishing enthusiasts!

Traditional Japanese knives are made from steel high in carbon, and this is mainly for two reasons:

  • due to the steel's pure composition, the blades can achieve an extremely fine sharpness,
  • for the same reason, they can be easily resharpened back to optimal shape.

Aogami #2 is one of the best in the high-carbon class, with added elements such as chromium (Cr) and tungsten (W) for improved corrosion and wear resistance, all while having an awesomely fine sharpness and being able to get resharpened easily. 

BLADE SHAPE:
Deba is one of the »big three« Japanese traditional kitchen knives, alongside usuba and yanagiba. They are essentials that every sushi chef needs to master.
Deba is a traditional knife a chef uses to prepare a whole fish: anything from cleaning, filleting, portioning fish, removing fins and heads, to chopping through smaller bones. It can also be used for preparing poultry and other meat with smaller bones.

This deba is special - it is a ryo-deba, meaning that it has a double bevel grind (unlike most deba knives), so it can be used by both right- and left-handed users. The double-bevel quality will also allow for easier sharpening. A ryo-deba can handle heavier tasks such as cutting through bones of large fish and chicken with ease. The blade is a well-balanced blend of robustness and precision. Filleting fish can be tricky and requires precise maneuvering, so using a sharp deba is essential in reducing the risk of damaging the delicate fish flesh.

The thick and heavy blade equips the deba for heavy-duty work that requires force – removing fins, tails, and fish heads, along with breaking down smaller bones.

STEEL:
Aogami #2 is a very popular steel in Japanese knife making and one of the finest high-carbon steels, meaning the knives forged from it will have exceptional edge retention and also sharpen very easily. At the same time, it is less resistant to corrosion, meaning the blade can develop a patina, while longer exposure to water or other corrosives could also lead to rusting. This is improved to some extent with the addition of chromium and tungsten, but it’s still a high-carbon steel that should be maintained accordingly (⚠️ read more about knife maintenance here). Aogami #2 steel is composed of carbon (C) 1.1 %, chromium (Cr) 0.5 %, manganese (Mn) 0.3%, and tungsten (W) 1.5%.

LAMINATION:
The blade’s core was laminated using the san-mai method to improve its structural integrity and subsequent ability to withstand impacts and prevent chipping. San-mai translates to “three layers” in Japanese, referring to a blade that is composed of a primary, inner layer of harder steel (hagane) and of two secondary, outer layers of softer steel (jigane) that protect the prior. → Read more on Blade Construction: Lamination.

GEOMETRY:
The knife is a double-bevel blade with a convex v-edge. It is heavier and stronger at the handle and thinner and more precise at the tip, towards which it tapers. This blade shape makes the knife easier to use because it is very responsive, easily maneuverable, and nicely balanced. This type of blade design is called distal taper - you can read more about it in the article on blade geometry.

BLADE FINISH:
The blade has a kuro-uchi blade finish. The Kuro-uchi finish on Aogami #2 blades provides a protective layer against rust and other external elements that can otherwise damage the surface. The kuro-uchi finish (kuro - ‘black’) is a layer of raw, protective patina on the outer steel. It gets a nice contrast from the hand-chiseled kanji on the blade. The kireha (lower part of the blade or ‘blade road’) has a classic cloudy kasumi finish.

HANDLE:
Japanese (Wa) style handle is made out of wenge wood and is topped with a black buffalo horn ferrule. The otagonal handle allows a comfortable and firm grip, suitable for both left- and right-handed users. Wenge wood features a unique open grain with a dark brown color and smooth, polished appearance. Handles made from this wood are highly durable and resistant to moisture.

A traditional feature of wooden handles is that over time the soft surface of the wood will lose its smoothness and shine, giving it an even better grip and making it even safer to use with wet hands. This extra friction of the "roughened" surface ensures that greasy, wet, and slippery palms don't slide forward on the blade during use.

☝️ 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.

☝️ THIS KNIFE MAY DEVELOP PATINA

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.

GENERAL KNIFE CARE TIPS:

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.
