DMT sharpening
- Thread starter jaydon
- Start date
I don't know for sure, but I would think that the continuous would be a little faster in cutting or polishing action.
I have several of the DMT dia folds (polka dot surface) in various grits and they work very well for my needs.
When I finally get around to buying bench stones, I will get the DMT double-sided dia sharps.

Jay, Put the math to it, its not difficult to determine the duo has half the surface as the dia on the same size stone. Hence, the dia surface will cut faster and has better value for your money. Yet, the duo is lighter for transporting and they make more money selling those stones as it has less produce on its surface. DM

The biggest advantages I see, with the continuous-surface hones (Dia-Sharp) are:
1.) More uniform finish left by the continuous-surface hones; especially noticeable at the finer grits.
2.) No 'holes' (or 'dots') to inadvertently snag a tip on the continuous hones; sometimes the belly of a blade can also snag a little bit in the 'dots' on the Duo-Sharps & Dia-Folds, if pressure is just a little heavy, or if the angle is a little too steep.
The 'Duo-Sharp' hones (interrupted surface) are manufactured to precision flatness, which is nice for sharpening tools with dead-straight edges, like chisels and plane blades, and also for lapping oilstones & waterstones. For the typically-curved edges of most cutlery, this is essentially a moot point, as the edge only contacts a very small area of the hone at any given instant. The Dia-Sharps are quite flat, just not to the same tight tolerances as the Duo-Sharps.
In terms of speed of metal removal, they're both quite fast in the larger bench-sized hones, and the continuous hones have the speed advantage in smaller hones, especially pocket-sized versions (I prefer my 'credit card' hones over my Dia-Folds for this reason). Use a little bit of water, or water + dish soap, or mineral oil to keep swarf from clogging the surface, and either type will perform very well.
