Precise & Long-Lasting Sharpness: Any serious chef knows quality knives are expensive. Keep yours cutting like for much, much longer with a rolling knife sharpener. With our easy-to-use system, anyone can get factory-sharp knives in minutes. Powered by Diamonds: The sharpening disc is plated with nature's hardest, most-effective sharpening stones: diamonds. The 400 grit size effortlessly removes the first layer of your knifes edge while restoring sharpness. A Finer Edge: A proprietary grit ceramic honing disk on the other end of the kitchen knife sharpener removes the burr of your knifes edge after the base sharpening. The result? A finer edge for more precise cutting that makes all kitchen tasks easier. Simple, But Effective: The rolling knife sharpening kit is deceptively simple, but also surprisingly functional. Simply choose your angle and use the magnetic knife holder to secure your blade. Then, roll the sharpening disc back and forth until sharp. Finally, flip the sharpener over and hone the edge using the grit ceramic honing disk. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
