Fascinating site, analyzing sharpness and sharpening with an electron microscope.

I have made the mistake of examining new vs used hypodermic needles under a regular microscope, and I understand why they are not reused anymore.
@werehatrack I’ve also examined high-quality vs cheap, and the difference is obvious. Not that anyone who uses them regularly wouldn’t already know this.
