Awesome thread and thank you so much for taking the time to do this! If there was a "thanks" button in B&B, I'm sure your thread & pictures would have garnered a significant number of thanks from fellow B&B'ers!
I have looked at a few blades in an electron microscope. In these images, the blade has been cross sectioned so that the edge profile is easily visualized. All are at 10,000x magnification (relative to a polaroid).
