The Ovela Knife Sharpener features three levels of increasing grit to sharpen your blades.
For badly worn knives, we recommend starting with the coarse sharpening wheel and working your way across to the fine sharpening wheel as the blade improves.
For regular sharpening, you may simply use the fine sharpening wheel.
Please see the image below for exact grit specifications for each setting.
Keep in mind that the coarser the grit level, the faster the device will erode the edge of the knife.
