So I just received my new Atoma #140 Diamond Plate, and immediately unpackaged it and put it to work on my Shapton Pro #1000 and #5000. All I can say is wow, serious cutting/flattening power! Within minutes I had near perfectly flat, fresh surfaced stones, and no stiction to speak of. What a winner! I realize that after the Atoma gets broken in it's cutting power will back off a little bit, but color me impressed!
