How To Choose A Right Grit? The higher the grit, the finer the stone, and the better result it delivers. Whetstones usually have medium (240 to 1000 grit )or high (1000 to 8000 grit.) The medium grit is for removing light scratches and grinding coarse edges, while the high grit is for polishing and refining fine edges. Use the high grit side to hone high-end professional cutting tools and the medium grit to sharpen regular knives. 240# to 400# Coarse Block : Repair the seriously damaged edge, suitable for blunt knives (Remove rust, scratches, and dull edges) 600# to 2000# whetting stones : Grinding (Sharpen blunt blades) to get a fine finish 3000# to 8000# Ultra Fine Stones : Precise Refining achieves a razor-sharp finish, used to eliminate burrs of the edge. Polish the edge gentler pressure until smoothly and keenly. Instructions for Use: 1. Fully immerse whetstone in water and soak until bubbles no longer appear (+/-10 minutes). While grinding, sprinkle more water on the top of the stone to ensure the top surface remains wet. 2. Coarse grinding: Using the #1000-grit side, slide the blade edge along the stone at a 10-20 degree angle applying consistent light pressure. Maintain steady angle on both sides for best results. After sharpening the tool, it needs to be honed with coarse grinding in half a year, that depending on situation. 3. Fine grinding: Then use the #6000 grit side to polish your knife, don't force too much. Generally you can use it once a week to keep your knife sharp as you want. 4. After sharpening the knife, clean the knife with wet cloth or water, then dry it. 5. Use a soft brush to clean the sharpening stone, then placed in a ventilated place out to dry.
