About
Sakai professional brand, big with sushi chefs abroad; 'Inox Honyaki' and White #2 honyaki are the reference pieces. Mark 酔心 is chiselled on wa-bocho.
Steels
- Shirogami #2 (White #2) — Hitachi/Proterial Yasuki carbon steel. Easiest to sharpen, takes the finest edge, rusts fast.
- Aogami #2 (Blue #2) — White #2 plus chromium and tungsten: better wear resistance, a touch harder to sharpen.
- Molybdenum-vanadium stainless — Workhorse stainless in Brieto professional knives and household lines from Tsubame factories.

Care for these steels
Carbon steel (Shirogami / Aogami / SK)
- Rinse and wipe dry immediately after each use — never leave it wet or in the sink.
- Do not put in the dishwasher. Do not cut acidic foods and walk away (lemon, tomato, onion will stain within minutes).
- A grey-blue patina is normal and protective; orange rust is not. Remove orange rust with a rust eraser or #1000 stone slurry.
- Before storing for more than a day, wipe with camellia oil (椿油) or any food-safe oil.
- Store dry, in a saya or on a rack — not loose in a drawer.
Stainless (VG10 / AUS10 / molybdenum / CROMOVA / SG2)
- Wipe dry after use. Dishwasher still not recommended — the heat and detergent dull the edge and loosen handles.
- Powder steels (SG2) chip rather than roll: avoid bones, frozen food and twisting cuts.
- Sharpen on #1000; finish on #3000–5000 if you like a polished edge.
