Ginsan / Silver #3 銀三鋼

What the research shows

Ginsan (Silver #3, 銀三鋼) is a stainless cutlery steel made by Hitachi in Japan, and it occupies a rare niche: it sharpens and feels like carbon steel but resists rust like stainless. The reason is its chemistry — roughly 1.02% carbon and 13.75% chromium, with essentially nothing else (no vanadium, no molybdenum). Unlike VG10 or SG2, which add hard alloy carbides for wear resistance, Ginsan's fine, simple grain structure takes a screaming-sharp edge and is easy to bring back on stones. It typically runs 60–62 HRC, so it holds that edge well. The tradeoff versus VG10 or SG2 is edge retention: you'll touch it up more often, but most owners find the sharpening pleasure worth it.

The Knives & Stones take

Honestly, Ginsan is the steel I hand people who say 'I want carbon steel sharpness but I know I'll ruin a carbon knife.' It's the same Hitachi family as White and Blue paper steel — and you can feel it on the stones. It's just 1.02% carbon and 13.75% chromium, no vanadium or molybdenum carbides gumming up the edge, so it sharpens almost like Aogami but shrugs off rust. At 60–62 HRC it's no slouch on retention either. From our shelf, the Hatsukokoro Ginrei Ginsan Gyuto 210mm Nashiji Ebony ($200 AUD) is the value pick — nashiji finish, ebony handle, genuinely hand-forged feel for the money. Step up to the Tsunehisa Ginsan Nawame Gyuto 210mm ($300 AUD) if you want the prettier hammered finish. Both beat VG10 for pure sharpening joy.
