The name “Rotoku” is derived from the Japanese number “roku” (“six”). Six virtues. One knife. A masterpiece of elegance and functionality. Performer knives are enhanced with a deep-black Diamond-Like Carbon (DLC) performance finish, which makes our blades uniquely strong and durable. This finish is heat-resistant, scratchproof, and resilient to damage. No matter the conditions, it sets new standards for frictionless slicing. The non-slip Hexagon-Power-Grip design on the handles guarantees unmatched control with every cut. A full bolster (the forged thickening between the blade and the handle) ensures perfect weight and balance. For those who never compromise, WÜSTHOF Performer.
