The Tsukasa Shiro Kuro Deba 105mm is hand-forged in Tosa, Japan using traditional techniques. Shirogami #1 (White Steel #1) carbon steel with soft iron cladding, finished in kurouchi. The smallest deba in the Tsukasa range - a thick-spined, precise fish knife for small fish and delicate butchery work.
Tsukasa Shiro Kuro knives are hand-forged in Tosa - a region of Japan with a centuries-long tradition of blade-making - using some of the oldest forging techniques still practised today. The steel is Shirogami #1 (White Steel #1, Hitachi Metals) - a pure high-carbon steel with no alloying additions beyond carbon, making it one of the easiest carbon steels to sharpen to a razor edge. The soft iron cladding protects the reactive core on the blade flats while the kurouchi finish is left intact, giving the knife a rustic, honest character and offering slightly better rust resistance than a fully polished carbon blade. The deba is the traditional Japanese fish butchery knife - its thick 6.4mm spine and 43mm blade height are designed to break down whole fish, sever small bones, and fillet with precision. At 105mm, this is the most compact deba in the Tsukasa range - ideal for very small fish, sardines, and precise home filleting where control matters more than reach. The oak octagonal handle is lightweight and traditional.
Care and Maintenance
Hand wash only - never dishwasher
Dry immediately after use - Shirogami #1 will rust if left wet
Apply a light coat of food-safe oil if storing for extended periods
Expect a natural patina to develop with use - this is normal and protective
Do not cut through large bones or frozen food - the edge will chip
