What's something that all good chefs have in common? Sharp knives. This 2-stage electric knife sharpener from Presto makes it quick and easy. Just draw the knife through the sharpener's 2 slots a few times and the blade is razor sharp. First, precision blade guides automatically hold the knife at the perfect sharpening angle. Then, professional-grade Sapphirite sharpening wheels create sharp edges with precision grinding. Fine honing completes the process, polishing the blade to an exact edge.
