This is a simple knife sharpener that produces fast results. Carbonitriding is an industrial process which forms a very hard, highly wear-resistant surface on steel. To sharpen, hold the Sharpener against a table surface right-side up and pull the blade through the steel discs with your other hand, using medium pressure. You’ll quickly feel the cutters biting into the blade and sharpening it. Our sharpener works equally well for sharpening a fixed blade knife, a folding pocketknife, or a kitchen knife.
The handle is made from Bubinga, a hard durable wood. Overall length is 7-3/4" the handle is 4-1/2". It really works. Great value. Thanks, Italy.
