The process of sharpening a dull knife is divided into three stages. Chef’s Choice Trizor XV comprises 3 sections to put your dull knife through them.

Both stages, 1 and 2, use 100% diamond abrasive that ensures ultimate sharpness. Plus, the blades will not get dull even after a long while of regular use.
