How many passes does it take most of you guys to get a close shave. I can get most of my face in 3 passes but my jawline and under my chin take upwards to 6 to get even remotely close. Is this a technique problem or is this normal? Should I crank up my slim adjustable in these areas? My skin doesn't seem to mind the areas that take me 6 passes it just seems odd to me that everything else can be done in half the passes?
