AOGAMI-SUPER-STAINLESS

Aogami Super Stainless

Blue Super Stainless

A proprietary laminated construction used by some smiths: an Aogami Super core cladded between stainless steel jackets. The concept marries the legendary edge of Aogami Super with everyday rust resistance. The exposed cutting edge still requires diligent care, but the body of the tool never stains. Popular for premium plane blades marketed internationally.
