Diamond Knife Sharpener | Rolling 15° Precision – GrainEdge

One Roll. A Razor Edge.
The GrainEdge is built for cooks who are done fighting blunt knives — and done fighting their sharpener. Instead of pulling a blade through fixed slots or wrestling with a whetstone, you simply roll the diamond-coated cylinder along the blade. One smooth, even pass. Done.

The Angle Is Already Set
A magnetic angle support locks the blade at a precise 15 degrees throughout every stroke. That's the sweet spot for kitchen knives — sharp enough to feel the difference on the first cut, stable enough to maintain the edge through weeks of daily use. No skill required. No trial and error.

Industrial Diamond. Walnut Finish.
The abrasive surface uses industrial diamond coating — fast-cutting, long-lasting, and far superior to ceramic or carbide alternatives. The walnut-effect housing and brushed metal detailing mean it sits on the worktop rather than hiding in a drawer. Compact, weighty in the hand, and built for daily use.

Designed for Straight Blades
Chef's knives, santokus, slicers, utility knives — the GrainEdge handles them all. Not suitable for serrated or single-bevel blades.
