When I was in my teens (70 years ago), I ground and polished a 6 inch telescope mirror to make a Newtonian telescope. The final polishing step used celenium oxide and a pitch lap. The results were accurate to within fractions of the wavelength of light. I don't see why we can't do the same thing to flatten the back of a tool. Has anyone thought of something like this? Obviously, you would only do it for something very special because it would take hours to do. I thought of it after seeing an ad for a Blue Spruce chisel, where they boast of such flatness.
