Thanks for contacting Tundra Restaurant Supply with your question Betty.
Using this Chef's Choice 464 Pronto™ Diamond Hone® Knife Sharpener is really easy. There are two slots corresponding to stage 1 and stage 2. Stage 1 is for sharpening, and stage 2 is for microhoning (shaping the blade after sharpening). All you do is get a good grip on the handle of the sharpener so it doesn't slip, put the bottom edge of your blade (edge closest to handle) in the stage 1 slot firmly, and pull the knife in a straight, controlled motion toward you. After a few strokes move the blade to the stage 2 slot and repeat the process. Nothing to it!
