OK, so I checked out my edges, at two different magnifications (not sure how to calibrate the microscope with the Mac, but used the highest magnification and lowest).

Dovo back from pro honing
Looks fine across edge.

Boker with 8 shaves
Looks good, there is a 2mm and 1mm shiny area in the middle, but otherwise the rest of the edge seemed fine.

Union Cutlery Spike with 40+ shaves
This had been giving great shaves, but has been pulling some lately. Wow! Here's the big one. In the middle of the blade, about 6-8mm long:

Comments? Thoughts? I take it, I'd need to bevel set this blade (time to try honing...)?

I also see a 2mm and 1mm spot towards the heel (sort of out of focus):

What usually causes small areas like this? ding? Is it just flattened a little? Doesn't seem like it is from stropping, due to the size. Is that a correct assumption?

The toe and rest of edge looks very good. Must be why 90% of my shaves are fine
