What is a Deba Knife?
The Deba (出刃包丁) is a traditional Japanese knife designed for breaking down and filleting whole fish — from removing heads and cutting through bones to making precise fillets. Its single-bevel edge and thick spine provide stability and cutting power.
Choosing the right Deba size depends on the size of the fish you usually handle:
150–160 mm: Compact and ideal for small fish (≤1 kg), great for head and fin work.
165–180 mm (recommended): A balanced, all-round size for everyday use with medium fish (1–3 kg).
210 mm+: Suited for larger fish (≥3 kg) like salmon or yellowtail — allows a full stroke along the spine without sawing.
Tip: The blade should be slightly longer than the fish’s body width for smooth, one-stroke filleting.
Steel & Maintenance
White / Blue Carbon Steel: Extremely sharp and hard (≈ 60–63 HRC) but requires careful maintenance — always hand-wash, dry immediately, and apply a light coat of oil when stored.
VG-series / Stainless Steel: Corrosion-resistant and easier to maintain, great for busy kitchens or humid environments.
Sharpening & Care:
Sharpen the bevel side at 12–15°, using a #1000 stone for shaping and #3000–#6000 for finishing.
Lightly flatten the ura (back side) to remove burrs.
Never use a honing rod; instead, strop gently on fine stones.
Each knife has its own strength, here’s how they differ:
Deba: Single-bevel, thick, powerful; made for butchering and filleting whole fish. Not intended for chopping hard bones or vegetables.
Santoku: A general-purpose Japanese knife with a double-bevel, thinner blade; excellent for slicing meat, fish, and vegetables but not for heavy fish work. Read the full comparison: Deba Knife vs Santoku
Chef / Gyuto: A versatile, Western-style double-bevel knife, great for most kitchen tasks but not optimized for cutting through fish bones. Detailed guide: Deba vs Chef Knife
Fillet Knife: Very thin and flexible, ideal for skinning and fine filleting after the fish has been cleaned; not suitable for breaking through bones. Learn more: Deba vs Fillet Knife
