Kanso is a design principle based on Zen philosophy. It means simplicity but simplicity that is achieved by eliminating the non-essential. In Kanso concept development, all that doesn't matter was left out and kept everything that does: high-performance steel, razor-sharp edge, perfect balance, and precision cutting control. The steel is Japanese AUS10A, a highly refined, high-carbon, vanadium stainless steel that takes a razor-sharp edge and holds it longer.Kanso's Heritage finish hides scratches and gives Kanso a rustic look that just improves with age. The handle is made of a wood called Tagayasan or wenge, which is sometimes known in Japan as iron sword wood. The handle contouring enables an easy chef's grip. Full-tang construction provides strength, balance, and easy cutting control.Like all Shun knives, Kanso is sharpened to a 16° cutting angle each side to cut cleanly and help preserve food's freshness and best taste.
