Ichizo 市蔵 165mm Deba Knife
Single Bevel · Shirogami · Right-Hand · Wa Handle

An authentic Ichizo (市蔵) deba knife, forged from Shirogami (White Paper Steel / Yasuki Carbon Steel) — one of Japan's finest traditional carbon steels, prized for its razor-sharp edge and exceptional sharpening response. The right-hand single bevel grind is the defining characteristic of the traditional Japanese deba, delivering clean, decisive cuts through fish and poultry. The thick spine and substantial weight provide the backbone required for breaking down whole fish with confidence. Fitted with a classic wa-style wooden handle. Brand new, never used, stored in its original box.

• Initial Sharpening Recommended: For best cutting performance, we recommend sharpening on a whetstone before first use. Even brand new blades benefit from a fresh edge to bring out the full potential of Shirogami steel.
• Hand Wash Only: Wash with mild soap, rinse thoroughly, and dry immediately. Never soak or leave wet.
• Wipe During Use: When cutting acidic foods (citrus, vinegar, etc.), wipe the blade dry periodically. Surface discoloration and patina are normal and not a defect.
• Oil for Storage: Apply a thin coat of food-safe mineral oil or camellia oil before long-term storage to prevent rust.
• Avoid Hard Materials: Do not cut frozen foods, hard bones, shells, or other very hard materials. This is a fish knife — use it accordingly.
• Cutting Board: Use a wood or soft plastic board. Avoid glass, stone, or ceramic surfaces.
