Collection: SPG2

SPG2 (Super Gold 2) — a next-generation, ultra-premium powdered high-speed stainless steel. Built on a high-speed steel base originally developed for metal-cutting industrial tools, it achieves an extraordinary combination of hardness and toughness. Its razor-sharp edge goes without saying, but what truly sets it apart is its 'naga-gire' — exceptional edge retention. With minimal need for resharpening, this steel maintains peak sharpness over the long term, delivering specs truly worthy of a knife built to last a lifetime.
