Steels

• VG10 — Takefu Special Steel's stainless with cobalt. The default steel of Tojiro's DP/PRO lines; also in damascus lines.
• Shirogami #2 (White #2) — Hitachi/Proterial Yasuki carbon steel. Easiest to sharpen, takes the finest edge, rusts fast.

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.
