Introducing the first electric knife sharpener that features Smith's patented interlocking wheel technology in a ceramic abrasive material. The Ceramic Edge Pro Electric Knife Sharpener uses interlocking ceramic sharpening wheels in its electric sharpening slot to produce a true, factory quality (or better) cutting edge on your knife blade. These sharpening wheels eliminate the possibility of marring or damage to your blade, reduce the amount of time needed to sharpen your knife, and leave no burr on the cutting edge. It features manual, pull-through sharpening slots for initial edge setting and sharpening serrated edge knives. It will sharpen knives of alloy, carbon, or stainless steel with a flat grind on both sides of the blade and knives with large or small serrations.
