+1 to the DMT credit card. I tried like crazy to get a slurry with the slurry stone with mediocre results. With the DMT, the slurry is quick and as others have said, it takes away some of the mirror-like finish. I have found this hone works SO much better after you break down the surface a little. All in all, I like this stone. Just be patient...I didn't have very good results with it at first. Now its a joy to use and my edges have been wicked nice
