Understanding the metal behind the edge


Steel Categories

Stainless Steel

VG-10 · AUS-10 · AUS-8 · Ginsan

The practical choice for everyday cooking. Stainless steels contain chromium (13%+) that forms an invisible oxide layer, protecting against rust and staining. Easy to maintain — just wash, dry, and go. Ideal for home cooks and professional kitchens where knives face moisture, acids, and heavy use without time for special care.

Carbon Steel

Shirogami #1 · Shirogami #2 · Aogami #2 · Aogami Super

The traditional choice of Japanese blacksmiths. Carbon steels achieve finer grain structures, enabling razor-sharp edges that glide through ingredients. They develop a unique patina over time — a badge of use that also protects the blade. Requires hand-washing and drying after each use, rewarding attentive cooks with unmatched cutting performance.

Powder Metallurgy

SG2/R2 · HAP40 · ZDP-189

The frontier of steel technology. Powdered metal is fused under extreme pressure, producing an ultra-fine, uniform grain structure impossible with traditional forging. The result: extraordinary hardness and edge retention with better corrosion resistance than carbon steel. Premium price, premium performance.
