Smith's Sharpeners Diamond Edge Elite Electric Knife Sharpener. 9 1/4" x 5" x 4 5/8". Light and dark gray composition base with non-slip rubber feet and black soft grip trim. Innovative wheel design provides razor sharp edge in minutes. Won't damage or detemper blade. Offers two stages of mechanical sharpening, coarse and fine, which allow you to match the condition of the blade with the appropriate rate of metal removal needed to sharpen the edge. Two stages of sharpening help prolong the life of the knife by only taking off enough metal to make the knife sharp while giving professional results every time. Use the coarse stage for quick sharpening of very dull or damaged blades. Use the fine stage to just touchup an already sharp knife. Also features manual pull-through slot in between the mechanical sharpening slots for sharpening the serrated portion of blade and for removing the burr from mechanical sharpening. Built-in blade guides ensure consistent angle sharpening. Comes with instruction booklet.
