I would have to totally disagree that the DMT 8K is better than a Norton 8K. In my experience the DMT is way more coarse than the Norton and definitely takes a break in period and does not produce the end result as consistent and as nice as the Norton. I find that attempting to shave off the DMT 8K is a challenge while very doable off the Norton 8K. It is a stone however, that will work after broken in and some folks like it and as we say, personal preference plays a big part in success for people.
Some stretch bringing this one back to life........
Have fun,
