This manual knife sharpener works in two stages. The first stage carbide (coarse) sharpens dull edges. The second stage ceramic (fine) provides a polished, razor-sharp edge. A reasonably sharp knife may only require this light honing. Use the sharpener to resharpen blunt knives or maintain sharp knives; it can be used for serrated and scalloped edges (ceramic fine stage only). The compact sharpener is already set at the optimum angle for German knives; simply pull your knife gently through each section. This sharpener is for left, and right-handed use.
Knife blades should be cleaned before, and after every sharpening
