Edit: I am leaving the original post below, and I will repeat this portion of the post below, where it makes sense with the rest of the comments; but, these “stones” are actually pretty good, but the Grit they give you is a lie. I am sticking with the two stars because I wanted a 600 grit stone, not a 6000 grit stone. Ok, that’s a bit of an exaggeration, but after all the posts and differing opinions I decide to do some tests. The test parameters were basically to flatten a plane blade with 220 grit and then use the DMT 600 side on one half of the blade and a Norton whetstone 4000 grit on the other half. the results are they did just about the same job. Actually, the 600 provided a bit more of a mirror finish and was a bit slower. Again, maybe this is just my stone or the way I use it, but I think this stone acts more like a 5,000/10,000. I will do some more testing, but this is my update for now.
I know some people love these stones, and that is why I bought one. But I have to say, while it will get the job done, it is not the best way to do so. The fact that better options are also cheaper just seals the deal.
The stones do cut, but so slowly. My understanding of the process of sanding or sharpening is like this: High grit = small scratches, low grit = big scratches: big scratches remove more material then small scratches- therefore, use a low grit to get the shape you want, then remove the scratches with higher grits. If that is your understanding, then skip these stones because in the time it takes the 600 grit to make an edge you can get a 4000 wetstone to do the same thing. Given how slow the stone is I don’t see the point. I wish I had bough something else.
Other people like these stones and if you are one of them, I have a DMT DuoSharp 600-1200 for sale, cheap. Otherwise, for the price of this stone you buy something like the Norton Wetstone 220/1000 4000/8000 kit.
