Rolling knife sharpeners can sharpen a variety of blades, including chef’s knives and paring knives. Use rolling sharpeners cautiously with serrated or ceramic blades, as they require specialized tools.
Attach your knife to the magnetic angle guide and roll the sharpener’s coarse disc first, then the fine disc, along the blade’s edge using light pressure. Continue until you achieve your desired sharpness. A strop can further enhance sharpness by polishing the edge after sharpening.
The frequency of sharpening depends on how often you use your knife. A honing rod can help maintain an edge by realigning the blade, but it does not actually sharpen the knife.
