The Tsukasa Shiro Kuro Difference

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. At 120mm and just 70g, this is an exceptionally light and nimble blade - well suited as a petty-style slicer, a sashimi knife for smaller portions, or an entry point into the yanagiba style for home cooks. 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 frozen food or bones - the edge will chip
• Sharpen with a whetstone to maintain the edge
• Store flat or in a knife roll to protect the blade
