Work Sharp Electric Knife Sharpeners are powered by premium abrasives, engineered specifically for every stage of sharpening with the E3, E4, and E5 models from complete restoration to applying a mirror finish on your edges.

Abrasive belts for the E3, E4, and E5 electric knife sharpeners are formulated, designed, and made in America by industry-leading abrasives manufacturer Norton for precision sharpening of high-strength steels. The grit symmetry, spacing, and backing flexibility are all designed to produce the optimal convex edge with minimal heating or material takeoff. If you’ve ever used a belt sander to sharpen, you know hot quickly the steel heats and how much excess material can be removed if you aren’t careful. Our abrasives are a key component of our success in the sharpening world.
