The ideal tool to achieve an excellent sharpening result quickly. The two-stage cut will turn the dullest knife into a sharp instrument. In the first stage (coarse), pull the blade through the carbide sharpener with a basic cut. The second stage (fine) smooths the cutting edge by grinding ceramic rods, and provides the finishing touch. Suitable for both plain edge and serrated blades. The grinding unit is removable and can be used right or left handed. Also features a stable, non-slip base.
