So I was doing another shave today and every so often the razor would tug. I have cut myself enough to know not to force it, so I would reposition and try again. I still have hair in some places it was tugging so I was wondering how one would tell the difference. This shave was by far my best and man is it smooth in the places I did 2x passes. So should it not tug on the hair at all, I assume my technique is at fault, but when in doubt stop is my motto here. Pull out the old cart razor and finish it up.
