Every blade goes through an ultra-precise 6 stage heat treatment which brings out the best qualities of each steel. We believe heat treatment is the key to a great knife. Even slight variations of a few degrees at any point in the process can cause the knife's hardness to vary throughout the blade. This is the reason it took 2+ years of research and development to dial in the specific heat treatment process that would ensure Cangshan knives are both hard enough to take a sharp 16 degree edge, and durable enough to keep that sharp edge during heavy kitchen use.

Cangshan bladesmiths are some of the highest paid bladesmiths in our district. We have one of the largest dedicated quality control staff in the knife district. Every knife from Cangshan is handcrafted and hand sharpened, these are real, passionate artisans creating beautiful, functional tools.
