Ginsan vs Aogami Super

Detailed metallurgical comparison between Silver Paper #3 / Silver Steel and Super Blue Steel.

GINSAN

Ginsan

Silver Paper #3 / Silver Steel

Ginsan (Gingami #3) is a stainless steel from Hitachi with a carbon level approaching white steel — a deliberate design to bring near-Shirogami sharpness in a rust-resistant body. Loved by professional Japanese chefs who need stainless practicality without sacrificing the razor-keen edge that carbon steel provides.

AOGAMI-SUPER

Aogami Super

Super Blue Steel

The highest-carbon variant among Aogami steels. Includes vanadium and molybdenum for extreme edge retention and hardness. Revered and feared in equal measure — its edge outlasts almost everything, but requires a master's touch to sharpen properly. The pinnacle of the Hitachi carbon steel family.
