With the diamond-coated grinding wheel of the Kyocera Diamond Sharpener, even the extremely hard ceramic blades of Kyocera knives can be easily sharpened by hand, restoring their usual sharpness. At the push of a button, the Kyocera Diamond Sharpener starts, and the grinding wheel rotates. After just a few strokes through the designated slot, the blade is sharp again. The sharpening angle is preset to ensure optimal results. Thanks to the ergonomic design, the application is effortless. If necessary, the grinding wheel can be replaced.
