The Professional EverSharp electric knife sharpener is a 3-stage system for restoring what your turkeys, tenderloins, roasts, hams, and gift packaging have taken away. The simple tool sharpens sporting and kitchen knives, including those with Santoku blades.
The EverSharp has an adjustable blade selector for sharpening at angles optimal for various types of knives: thick for hunting knives; medium for chef's and standard kitchen knives; and thin for fillet and paring knives.
To use, you'll draw each knife a few times through each of the 3 slots. Slot 1 contains a Sapphirite coarse-grinding wheel that creates a proper angle, slot 2 a Sapphirite medium-grinding wheel to give the blade a precision edge, and slot 3 an extra-fine-grit ceramic wheel that polishes the blade to an edge.
