Work Sharp Culinary Ken Onion Knife Sharpener

Yes, the Work Sharp Culinary Ken Onion model is designed to handle serrated blades. You should use the dedicated sharpening slot for serrations to ensure the belt maintains the correct geometry of the teeth.

The sharpener uses flexible abrasive belts that are much gentler than traditional grinding wheels. While it does remove a small amount of metal to create a new edge, it is significantly less aggressive than manual pull-through sharpeners.

It works well for standard double-beveled knives, but you should be cautious with single-beveled or traditional Japanese blades. Because the machine is designed for a specific edge angle, it may not be suitable for specialized blades that require a unique geometry.

You will notice the sharpening process takes longer or requires more passes to achieve a clean edge. When the belt appears worn, clogged with metal dust, or loses its cutting efficiency, it is time to swap it for a fresh one.

The sharpener features built-in angle guides that take the guesswork out of the process, making it very beginner-friendly. You simply pull the knife through the guide at a steady pace, and the machine handles the precision work for you.

This model is specifically engineered for kitchen knives. While some users attempt to sharpen other tools, it is not recommended as the guides and belt speeds are optimized strictly for the geometry of culinary blades.
