wow, I just made a pretty sharp edge on a mill (not intentionally)

I wonder if that would work as an intentional process....

how do industrial blade sharpening systems work?.....

@la I always assumed it was based on grinding the blade blank against a rotating abrasive wheel at a fixed angle, but never looked into it (or what rough-sharpening might be done prior to that point)
