Electric Knife Sharpener

Ultra-sharp. Precise. Safe.

The Diamond Sharp electric knife sharpener from CASO Design is your perfect everyday companion: It works on both smooth and serrated blades and delivers ultra-sharp results—even if you have no prior experience.

The DiamondSharp features a precise 3-step sharpening system with two diamond-grinding stages and a ceramic polishing stage, and sharpens all common types of knives—from kitchen and household knives to hunting and pocket knives. The precise angle guidance and the diamond coating on the diamond-grinding stages guarantee ultra-sharp, brilliant results: The coarse grind (diamond) shapes the basic cutting edge and restores the original V-grind, while the fine grind (diamond) removes burrs and smooths the cutting edge. Finally, the polishing stage (ceramic) ensures a particularly sharp and finely aligned cutting edge.

The compact and powerful DiamondSharp knife sharpener is exceptionally easy and safe to use, making it ideal even for those with little prior experience with knife sharpeners. Thanks to its automatic, user-friendly sharpening process, the DiamondSharp delivers fast and reliable sharpening results for everyday use. The robust housing and the sturdy, arched design of the blades with three bevels ensure an exceptionally long service life.
