This electric knife sharpener is designed to deliver ultimate convenience for users. Its EdgeSelect sharpening system features three stages: Stages 1 and 2 utilize 100% diamond abrasives to quickly and effectively sharpen and hone blade edges, while Stage 3 polishes the blade to restore its sharpness and refine the finish.
