So, I've been using Feather Super Pro AC blades for several weeks now. I can get 3 perfectly good shaves with one blade, then the 4th shave can get a bit choppy, but passable. So, after 3 shaves with my last blade, I decided to try stropping it, figuring if it didn't work I wouldn't lose out on much. It definitely made enough of an improvement to make the 4th shave fantastic. Does anyone strop their Feather AC blades? I realize they are disposable to cut down on maintenance, but I'd like to extend blade life a little if possible.
