Placing the diamond stone on top of the whetstone, use circular and up-and-down movements to begin flattening process. For better results, draw a grid on the whetstone with a ballpoint pen or a pencil (do not use markers, those can be absorbed into the surface of the stone). When the grid is no longer visible, the stone is flattened. Thoroughly rinse both stones to remove any excess material. Flattening whetstones to up to #5000 grit will get you good results by only using the Naniwa diamond stone, while for higher granulations we recommend finishing with the\u003cspan\u003e (included) dressing stone\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eto get a smoother\/finer surface on the whetstone. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor knife repairs\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e- place the diamond stone on a flat surface and make sure it won't move around (use a\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e\u003ca href=\"https:\/\/sharpedgeshop.com\/collections\/sharpening-tools\/stone-holder\"\u003estone holder\u003c\/a\u003e\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003efor the most secure position).

A lower granulation (#140 - #600 grit) is recommended for initial sharpening, followed by a #1000 grit diamond stone and, if desired, even finer grits.
