Thread: Hones, Edges and Bevels under the Microscope

Ah, I see you taped the edge for the test pass. That changes my interpretation quite a bit. I was assuming the odd look as you got away from the edges were purely due to DOF issues, but knowing there's also a double bevel explains a lot. For one thing, there appears to be some evidence of what has been long suspected - the pasted edges seem slightly ovalled - this is especially evident comparing the 5 stroke chrome oxide photo vs the 10 stroke chrome oxide photo vs the base 8k photo. Edit: ARGH! never mind! of course the edge is ovalled - the spine is propped up!

I'm curious how the edges were lit? Some of the photos show keyholed lighting patterns and some show even lighting patterns. Was the light source fixed to the scope or was it a separately positioned source? It's possible that the reason some edges look rougher than others is simply because the lighting in those photos allowed us to see better.

Regardless, these photos give some insight into into possible explanations for what we have experienced ourselves during our shaves. Great work!
