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 150mm, this petty is the go-to knife for detail work - peeling, trimming, segmenting citrus, and any task that calls for a short, agile blade with a pointed tip. The kurouchi finish is left intact on the blade flats, giving the knife a rugged, honest character and offering slightly better rust resistance than a fully polished carbon blade.

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 on a magnetic strip or in a knife block
