Discover the Kurokaze Ryo-Deba Aogami #2 Kuro-uchi 180mm (7.1") – a robust, double-bevel deba knife crafted for fish enthusiasts and chefs alike. Unlike traditional single-bevel debas, this Ryo-Deba is easier to sharpen and ideal for tackling tough tasks, from slicing through large fish bones to handling chicken. Designed with a symmetrical blade, it’s perfect for both right- and left-handed users.
Whether you're a professional chef, an avid angler, or a home cook who tackles whole fish and chicken, this knife offers the strength, balance, and control you need.
BLADE SHAPE:
Deba is one of the »big three« Japanese traditional kitchen knives, alongside usuba and yanagiba — essential tools for every sushi chef.
Traditionally used to prepare whole fish, the deba excels at:
- Cleaning and filleting
- Removing fins and heads
- Portioning fish
- Chopping through smaller bones
- It can also handle poultry and other meats with fine bones.
This version is a ryo-deba — a double-bevel deba — which makes it easier to sharpen and more versatile in the kitchen. Its thick and heavy blade offers both power and precision, ideal for clean cuts through flesh and bone while minimizing damage to delicate fish meat.
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. 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.
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.
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.
HANDLE:
Japanese (Wa) style handle style handle made out of wenge wood with a buffalo horn ferrule. The octagonal handle allows a compact and firm grip during the filleting process without slipping or causing any injuries, which is critical when working with raw fish.
|
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. |

☝️ 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).

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.
