Design Meets Precision Blades

Originating in Cangshan, China, this brand is rooted in the principles of “beautiful function.” Their blades combine German, Swedish, and Japanese steels with a six-stage heat treatment process to deliver high performance and aesthetics.

Our sharpening process is built to respect both the visual integrity (e.g. damascus, finishes, patterns) and the technical geometry (edge angles, steel behavior).

Safe, USPS-Compliant Shipping

Your kit meets and surpasses USPS Publication 52, Section 443 standards for shipping knives. Reinforced outer packaging, cushioned inner sleeves, and no external markings ensure discreet and secure transit. 👍
