Review on 💎 DMT 6-Inch Diamond Whetstone W6EFC: Enhanced SEO-Friendly Product by David Carmody

I'm not sure if I received a defective product but I've only sharpened 3 of my chisels and these stones are already useless. I smoothed the backs of the three chisels with a rough cutter and beveled them to 25 degrees before moving on to the red and green stones to set the bevel to 30 degrees. When I got the rough stone to the fourth chisel, absolutely nothing happened. The back did not flatten out and the stone seemed perfectly smooth. There are light scratches on the back but the material does not appear to have been removed. I am incredibly disappointed in these stones as they are useless to me now. They also started discoloring halfway through sharpening my first chisel. I guess I'll have to look around for a new brand of diamond stones as I still have 4 chisels and 3 planes to sharpen.
