The Zakuri Difference
Zakuri is a small workshop in Tosa - a region of Japan with a centuries-long tradition of blade-making distinct from the more famous centres of Seki and Sakai. Blacksmith Michikuni Tokaji hammer-forges each knife individually using San Mai construction, where a hard Aogami #1 core is clad between layers of soft iron. Aogami #1 (Blue Steel #1) is among the highest-grade carbon steels used in Japanese knife-making - a tungsten and chromium-enriched high-carbon alloy that takes an exceptionally fine edge and holds it through sustained hard use. At 240mm, this yanagiba is a nimble entry point into the style - long enough for clean drawing cuts through raw fish and proteins, but more manageable than the 270mm for home kitchen use. The kurouchi finish is left intact on the blade flats, giving the knife a rugged, honest character.
Care and Maintenance
- Hand wash only - never dishwasher
- Dry immediately after use - Aogami #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 long blade
