You may have noticed your average knife sharpeners don't really work. Whetstones are ideal, but they need to be soaked for hours and take some practice to perfect. The solution is this three-stage knife sharpener, combining the world of the whetstone with the simplicity of countertop sharpeners. Including coarse, fine, and medium, the three stages of this sharpener stays wet after you briefly dunk the whole mechanism in water. The liquid keeps the blade moving along each of the hones, quickly and easily taking dull and chipped knives from worthless to the sharpest tools in your culinary shed.
