I'm glad to see those pictures at the bottom. One of the things that always comes up with tools when I suggest oilstones are optimal for someone who wants something that makes sense in the context of work is "well, diamond plates are better than oilstones". I noticed long ago that when you're using a DMT, you get odd random deep scratches, that cosmetically is annoying. For woodworking, I don't know if they really matter, but it always struck me as odd that even when you use a broken in DMT or other monocrystalline plate, you get some scratches that are difficult to remove - now I see why.
I don't get the same thing from a broken in eze lap, but even the ezelaps are pretty aggressive when they're new (DMTs are all mono crystalline and ezelaps are a combination of mono and poly).
I don't get the same thing from atoma, either, but the way the atoma diamonds are arranged in piles makes them fantastic for lapping stones, but a bit funny feeling for honing things in the larger particle sizes. Like honing on a zipper.
