Really great; saved my chisels

This diamond stone is really useful. After attempting to regrind, then hone some old chisels on a set of waterstones, I had almost ruined the chisels due to the fact that the large amount of grinding that had carved bowls in my stones (which I didn't notice right away).

I purchased this diamond stone to true the water stones and it does a great job, rendering them flat with just a few strokes. The added bonus was that I also used the diamond stone for the first stage of regrinding the chisels; it was much faster than the water stone and stayed flat during the process.

Unless you have a method of securing the diamond stone to your bench, get the available holder, its definitely worth the money.

I did notice a bit of rust forming on the steel substrate after leaving it wet, so I now dry it off after each use.

Super flat and super fast

A super value sharpener for all your edges no matter what they are made of. Carbide, ceramic, tool steel, high speed steel all are sharpened very quickly to a very keen edge. The double sided design is a great space saver and the whetstone size is great for large plane iron flattening / sharpening. This premium value seems to be found in all the rest of the DMT product line too.
