Each whetstone in Norton's sharpening range is dual sided, with a coarse side for quick sharpening of dull and damaged knives and a fine side for finishing and polishing the edges. All whetstones feature a non-slip base for safety during use. Norton's 1000/3000 grit whetstone is ideal for sharpening and light polishing blades.
