This three stage electric knife sharpener was top rated by a major examining firm for sharpening ability, ease of use, and features. It sharpens knives in a different and better way by grinding a double beveled edge that is suppose to be sharper, and stay sharper longer.

“The device has three slots that each perform different sharpening functions, only requiring

you to slide the knife blade through the slots; the first sharpens the blade using 100% diamond abrasives, the second has a hardened miniature steel that forms an edge with microscopic serrations, and the third uses a patented stropping disk to polish the edge. “

Cost is about $150
