I obviously don’t know, but from videos I’ve seen of making DE blades, the tradeoff between cost and precision favors cost. My assumption on the sputtering is that it normalizes the edge and that the coating reduces harshness when the blade is at its sharpest.
My scope is calibrated so the 50 micron scale at the bottom left is reasonably accurate. It’s amazing how much better the resolving power of a SEM is at similar magnification.
After AA I’ll do a sequence with a DE blade. I’ve only done a GEM and Kismet so far.
