TOJIRO SHIROGAMI Deba 180mm

At 180mm the deba reaches its standard professional size - heavy enough at the spine to power through fish heads and collarbones, long enough to fillet a wide range of species cleanly, and precise enough at the tip for detail portioning work on smaller fish. Tojiro builds this one in Sanjo City with Shirogami (White #2) carbon steel at the core and soft iron cladding, a pairing that has defined traditional Japanese fish knife construction for generations. It is an honest, capable knife at a price that makes it an accessible entry into serious Japanese single-bevel work.

Shirogami (White Paper Steel) is a high-purity carbon alloy that achieves an acute, polished edge and sharpens with immediacy that stainless steels rarely match. The soft iron cladding develops a natural patina with use and adds toughness to the construction without interfering with the edge steel behavior. The single bevel grind is traditional - aggressive cutting face, hollow-ground back - and the kurouchi hammered finish on the cladding gives the blade road a textured, protective surface. The Ho wood handle with plastic ferrule is a standard traditional fitting that many buyers choose to upgrade over time, and adding a saya for blade protection is a worthwhile consideration.

What Customers Are Saying: A professional who processes more than 20 pounds of catfish daily describes this deba as a real workhorse - capable of clean fillet work on smaller fish despite the substantial size. Multiple buyers highlight that the blade takes a razor edge on a stone with relatively little effort, and that the sharpness exceeds what the price suggests is possible. Mark Richmond personal customer service during a shipping delay earns a specific callout from one buyer. Several reviewers note that a handle upgrade and a saya are worthwhile additions, and one buyer who has used the knife through years of professional fish work calls it a whole lot of knife for the money.

Care Instructions: Shirogami (White #2) carbon steel with soft iron cladding means both the edge and the blade road are reactive. Wipe and dry the knife immediately after use - do not leave it wet or in contact with acidic foods. Apply a light coat of camellia oil for storage. Hand wash only - never the dishwasher. A natural patina will develop with use and actually helps protect the steel. Free shipping over $100.
