The Work Sharp E2 Electric Kitchen Knife Sharpener is a new, innovative way to sharpen every knife in your kitchen. Unlike most sharpeners that use diamond grind plates, Work Sharp Culinary kitchen knife sharpeners use flexible abrasives for a gentler sharpening and a sharper edge. Built-in angle guides ensure the perfect, uniform edge for a flawless slice from tip to heel, and an automated timer lets you know you when your knife is sharp.
