Thanks for the excellent post Bart. I have experienced the flutter too.

Your mention of purposely dulling a sharp edge brings to mind the practice of some DE shavers of 'corking' Feather blades to take a bit of the edge off. (no pun intended)

Having noticed that they were frequently smoother on the second shave the idea of running them lightly over a piece of cork is practiced by some guys.
