Use the gift brush to remove the grinding dust from the sharpener and the microfiber fabric to gently wipe the knife after each use. ERGONOMIC DESIGN WITH STAINLESS STEEL HANDLE INSTEAD OF CHEAPER RUBBER. In tests, the top part of the handle easily gets dirty and hard to clean if it is cheaper rubber. So we change that part into high quality stainless steel while keep the bottom part be soft rubber to ensure the holding stability. PLEASE NOTE. This knife sharpener is only suitable for non-coated steel knife. Ceramic and other serrated knives should NOT be used in the sharpener. Also do NOT put the sharpener in the dishwasher or submerge in water.
