Kidding aside, I've got a serious question gents.
You know how we check if the edge reflects light when we grind bevels to make the two sides of the edge meet at the apex.
If it still reflects the light, we keep grinding.
Am I thinking right, that when the edge no longer reflects light, we've got it to 0.5 micron width, i.e. to the wavelength of the light?
The light wave literally breaks over the edge that is too narrow to reflect it back.
