Why is the "burr"apparently so far down the edge when sharpened with the ceramics in the first picts?

That's dust, its very hard to get a pic at that magnification and not see some little specs of dust.

Knifenut, Those are really great pics. Have you ever tried raising the angle on the aligner a couple degrees a doing super light alternating strokes to see if the burr improves? When I don't strop that is the method I use. Of course, my OCD usually causes me to go to .05 microns on all of my edges. the burr on those edges appears to be so small as to not make much of a practical difference, but then again when you know it can be better it is hard to leave well enough alone and not hit the finest grit you have laying around.

If I couldn't maginfy it that much I would never know there was a burr their. I can sometimes feel a slight burr in spots when I drag it across my nail but with the examples pictured I could feel or see nothing. I don't think that small of a burr would have any effect in performance because in the first cut the damage would extend past the point of the burr. I guess I should have added that when I sharpened it with the diamond stones I was doing it freehand.

As for raising the angle and doing light strokes that's what I did with the ceramic example.

Thanks for the explanation. I was pretty sure that the burrs were small enough to be pretty much irrelevant to performance, but 400x really can expose some things you can't believe are there, and it just goes to show that all it takes it magnification to expose any flaws in a seemingly perfect edge. I'm sure it goes without saying that both the DMT and UF ceramic edges whittled hair with ease. The burrs look so small that at 100x I would miss them, and from experience I know when an edge looks clean at 100x the edge will last a long time.
