Introducing the Hidetsune Ryo-Deba Aogami #2 Kuro-uchi 150mm [KOB], a premium Japanese knife crafted by Hidetsune, a smithy with over 100 years of tradition. Designed for professional chefs and experienced home cooks alike, the Hidetsune Ryo-Deba is perfect for those who demand reliability and versatility when preparing fish or other meats. 

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.

Unlike typical single-bevel deba knives, this model features a double bevel grind—known as a Ryo-Deba—making it easier to sharpen and ideal for both right- and left-handed users. Its sturdy blade is designed for heavy-duty tasks like filleting, portioning, and cutting through the bones of large fish and poultry with ease.

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. ⚠️ Read about knife maintenance here.

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 features a double-bevel blade with a convex V-edge. It is heavier and stronger near the handle, tapering thinner and more precise towards the tip. This design makes the knife highly responsive, easily maneuverable, and well balanced. This blade profile is known as distal taper — you can learn more in our article on blade geometry.

BLADE FINISH:
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:
The handle is made from durable Japanese oak, shaped into a traditional octagonal (wa) form for a comfortable grip in both left and right hands. It’s treated with a Baikoku (梅黒, “black plum”) finish—a traditional Japanese technique that gives the wood a deep, dark tone and enhances its resistance to moisture and wear. Stylish, lightweight, and built to last.

THE SMITHY:
Hidetsune is a legacy forged through generations — the name combines the master’s "秀" (Hide) and the founder’s own "常" (Tsune). Now in its third generation, this century-old blacksmith tradition crafts robust tools like axes, hatchets, and Deba knives, blending heritage with exceptional strength and precision.

☝️ 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.
