Features of DMT Dia-Sharp

100% usable abrasive surface

The continuous diamond layer on these sharpening stones ensures even and fast results. No holes, no gaps - just 100% usable surface. This allows you to work faster and more precisely. And because the diamond layer remains so flat, you never have to waste time flattening your stones. Every stroke feels steady, controlled and efficient. Perfect for any knife fan who likes to keep their tools in tip-top shape. And all of that without water or oil: just grab a stone and get started.

For any task

From your compact EDC pocket knife to your toughest kitchen knife: there is always a Dia-Sharp sharpening stone to suit your needs. They come in multiple sizes - from 4 inches for on-the-go to 8 inches for the bigger knives. DMT supplies them in a variety of grit sizes, from extra extra coarse to extra extra extra fine. This way, you can start coarse and gradually work towards a razor-sharp finish, without changing systems. The steel base ensures stability during sharpening, so there will be no unwanted wobbling.
