SG-II (R2) Steel

SG-II (SG2), also known as R2, is a powdered stainless steel. Powder metallurgy gives it a very fine, even grain, so it can be hardened well beyond ordinary stainless steel while staying tough. It holds a sharp edge for a long time and needs little maintenance.

This collection includes double-edged SG2 gyuto, petty, kiritsuke and utility kiritsuke, plus single-edged yanagi and yanagi kiritsuke. Finishes include polished, hammered and Damascus, with rosewood, ebony, ocean blue and stabilized maple burl handles. See also Ultra-Hard Japanese Steel Knives.
