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-2

Aogami #2

Blue Paper Steel #2

Similar to Aogami #1 but with slightly lower carbon and tungsten content. Offers an excellent balance of edge retention and toughness, making it the most-used steel among Japanese master blacksmiths. The sweet spot of the Aogami family — demanding enough to be worthy, forgiving enough to be reliable.
