The Smith's Edge Pro Compact™ Electric and Manual Knife Sharpener easily sharpens dull edges with the bonded synthetic sharpening wheels and keeps razor-sharp edges strong with just a few swipes through the ceramic rods. The wheels last long, provide a uniform cut and create minimal heat buildup in order to prevent detempering. The sharpening angles are preset to ensure that edges are uniform and strong. The soft-grip rubber handle and nonslip rubber feet provide stability and safety.
