MIYABI Whetstone/Sharpener A sharpener that can also be used for high-hardness knives. This sharpener can sharpen high-hardness (HRC60 or higher) stainless steel knives that could only be sharpened with a whetstone before. With diamond coarse grinding rollers and ceramic finishing rollers, slide the knife (pull towards you) to restore sharpness. Can also be used for ZWILLING (Zwilling)'s high-hardness knives, TWIN Cermax MD67 and TWIN Cermax M66. If you use the sharpener for a long time, the sharpness will not be restored. We recommend sharpening with a whetstone to repair the overall angle of the knife to a sharp angle.
