The only sensible thing to do as far as I am concerned when dealing with a full blow beard is to use an electric hair trimmer first to get rid of the bulk of the growth. That done you are in sensible territory to use a bladed razor to do your actual traditional shave. At least that is what I'd do if I ever grew a full on beard.I considered this also, but at least in my experience, a couple of days growth isn’t as significant as a beard that’s been growing in for weeks or months
