This image is of a Fujihiro knife off a Nakayama waterstone...
At this magnification (whatever its actual magnification is) the edge condition can be clearly seen. With knives that slice a small amount of edge breakaway is acceptable (as we know from bread knives/saws) as long as most of the edge is intact and sharp, as this one is right up to the edge.
The abrasion pattern off a natural waterstone is a bit more random and soft than man made abrasives. That's what gives the finish that misty look. In more recent years I have been putting a nano-bevel on the very edge, so this image goes back a few years when I was sharpening the full bevel each time. I can't think of the last time I worked on a full bevel on any of my knives... different story with my family and friends who are much harder on theirs and return them to be rehabilitated from time to time!
