Manufacturer's Description
Patented 2-stage electric knife sharpener uses orbiting 100% diamond abrasives and foolproof magnetic guides to give knives sharper, longer-lasting edges. Safe for quality knives. Sharpens full blade edge of kitchen, pocket and fishing knives. One-year limited warranty. Assembled in the U.S.A. Chef'sChoice® sharpeners are the only electric knife sharpeners recommended by cutlery experts and leading professional chefs for sharpening quality cutlery. The Model 310 incorporates 100% diamond abrasives in all three sharpening stages to create the unique, patented Trizor® edge. The diamond abrasives will last for many, many years without need for repair or replacement. If the abrasives need replacement, send the sharpener back to EdgeCraft and, for a nominal fee, EdgeCraft will replace the abrasives, clean and lubricate the sharpener, and ship the sharpener back. The abrasives, however, should last a long time with normal household use.
