Toothy vs Polished Edge

[Tman]

I'll put in my two cents for optical microscopes and edge photography in general. A combination of an edge sharpness tester and a microscope is simply unbeatable. Both devices support each other and help to verify or expand the results of the other.  Often the results of my edge sharpness tester will leave me puzzled.  The microscope fills in the gaps and provides  a clear explanation of why I am receiving a particular set of  test results  The two instruments are simply essential tools in my sharpening area and have resulted in a much better understanding of the sharpening process.
