The crafting of single-bevel knives, such as Deba, requires exceptional skill and extensive experience from blacksmiths. Therefore, it is recommended to purchase these knives from trusted manufacturers, such as Sakai Takayuki.
The Deba knife is primarily designed for filleting fish, but it is also suitable for processing small poultry with bones. Kiri-Deba is a variation of this knife, originating in Sakai City. Its distinctly pointed tip makes it ideal for piercing tough or slippery fish skin. The heel of the knife can be used to break small rib bones in smaller fish or to cut off the head or fins. With a blade length of 150 mm, it is perfectly suited for standard fish varieties consumed in this region.
This knife is made from Shirogami #2 steel, considered an ideal material for such blades. Its texture closely resembles Tamahagane steel, which has been traditionally used for crafting katanas in Japan for centuries. Water-tempered, it achieves a hardness of 61-62 HRC, which many expert blacksmiths consider ideal for single-bevel knives.
The D-shaped handle, crafted from Japanese yew wood combined with buffalo horn, follows the traditional Japanese knife-making style.
Note: This knife is suitable only for right-handed users. It comes with a certificate of origin and a blacksmith’s warranty.

Care and Maintenance of Japanese Knives
✅ Proper Knife Care
Always hand wash the knife with warm water and dry it immediately with a soft cloth to maintain sharpness and quality.
To keep the edge precise, water stones are recommended for sharpening, while ceramic honing rods help refine the blade during regular use.
Store the knife in a safe place, avoiding contact with other kitchen utensils that could damage the edge.
Use wooden, plastic, or rubber cutting boards to protect the blade and extend its lifespan.
⚠️ Special Note for Traditional Japanese Steels
Japanese knives made from high-carbon steel require extra care to prevent oxidation and rust.
After each use, thoroughly clean the blade with warm water and immediately dry it completely with a soft cloth.
Applying a thin layer of mineral or camellia oil occasionally can further protect the blade from corrosion.
Knives should be stored in a dry place, avoiding prolonged exposure to moisture or contact with aggressive cleaning agents.
? Improper Use
Do not cut on hard surfaces like glass, ceramics, steel, metal tables, or baking trays.
Avoid cutting bones or frozen ingredients, as this can damage the blade edge.
Do not wash the knife in a dishwasher—chemicals and high temperatures can negatively impact the blade and handle.
A Japanese knife is a precision tool, designed for specific culinary tasks. Do not use it for inappropriate activities like chopping bones, opening cans, or handling non-food materials.
