E4 Electric Knife Sharpener

The Work Sharp Culinary E4 electric kitchen knife sharpener uses controlled speeds and timed sharpening cycles to shape, sharpen and refine all your kitchen knives at the touch of a button. Based on traditional belt sharpening practices, the E4 creates a sharp-as-new edge the same way manufacturers sharpen knives at the factory.

Precision sharpening guides, controlled speeds, and high-performance sharpening belts make the E4 knife sharpener easy, clean, and gentle on knives.


One Touch Programming

One Touch Programming has the sharpening knowledge built-in. Push to Shape, Sharpen, or Refine, and the E4 automatically adjusts speeds and running time to match the degree of sharpening desired.

Precision Sharpening Guides

Sharpening guides eliminate guesswork and uneven sharpening. The E4 applies the 17° Work Sharp Edge – a balance of the precise cutting ability of Eastern knives and the strength and durability of Western knives. Combined with the convex shape of the cutting edge created by sharpening with belts, your knives will perform like new or better, stay sharp longer, and continue to provide the value and integrity your knives were made to deliver. The E5 Upgrade Kit (sold separately) expands the sharpening capabilities of the E5 or E4 with 15° East and 20° West sharpening guides.

Professional Grade Sharpening Belts

The E4 electric sharpener uses a professional grade sharpening belt engineered specifically to sharpen knives without removing excessive material – protecting the value of your kitchen knives, extending their life, and maintaining sharp-as-new cutting performance. The E4 comes with one sharpening belt installed and ready to use, with two additional belts stored inside the unit. Learn more about our premium belts here.
