The Smith's Diamond Edge Electric Knife Sharpener incorporates both mechanical and manual sharpening elements in one unit. The mechanical sharpening slot features a diamond coated sharpening wheel and blade guides to hold your knife at the correct angle during mechanical sharpening.
After sharpening both sides of your blade with the diamond sharpening wheels, Smith's recommends using the crossed ceramic stones in the manual finishing slot for the final edge honing. Ceramic stones remove any burrs left on your blade from mechanical sharpening and put a razor sharp edge on your blade and can be used for a quick touch up of an already sharp blade.
