>I think sharpening chisels is a bit of a lifetime skill, you can get a workable chisel first time, but after nearly thirty years I still don't feel as much like a human surface grinder as I would like to.

The one way in which saws are a whole other thing is that all the teeth work together in concert. I have used some rather poorly sharpened chisels with bevels nowhere near a spec and the edge at an angle yet they work. String 50 of those together on a saw and the result may not be as pleasing.
