Marks on the blade

About

Sakai wholesaler behind the 景清 Kagekiyo brand: Blue #1 kurouchi, Ginsan, SG2 and the cheaper 'Chromax' semi-stainless line; blades finished by named Sakai sharpeners (e.g. Wakae). Has its own shop in Sakai. Not related to Babacho (馬場長) of Mitsuke, Niigata — different kanji, different company.

Steels

• SG2 / R2 (powder stainless) — Powder-metallurgy stainless. Long edge life, chips if abused. Kataoka's TAMAHAGANE and Kiryu's SPG2 line.
• Aogami #1 (Blue #1) — Blue #2 with more carbon and tungsten: the hardest of the classic Yasuki carbon steels apart from Super; edge lasts long, chips if abused.
• Ginsan (Silver #3, Gingami 3) — Hitachi/Proterial stainless that sharpens almost like White steel: the usual 'stainless wa-bocho' steel in Sakai, and the Hatsukokoro Ginrei line.
• VG10 — Takefu Special Steel's stainless with cobalt. The default steel of Tojiro's DP/PRO lines; also in damascus lines.

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.
