Sharpen household knives of alloy, carbon or stainless steel with this sharpener, which offers electric and manual sharpening in one compact unit. The electric sharpening slots use a synthetic abrasive sharpening wheel with blade guides to hold your knife at the correct sharpening angle automatically. For manual fine-tuning, the crossed ceramic rods create a pre-set sharpening angle that lightly hones both sides of your blade, giving it a polished, razor-shape edge. The rubber handle offers comfort and control of the unit, and the non-slip rubber feet prevent slipping. 3-year limited warranty.
