Irritation mach3 v. Straight
Here is something I noticed. When I used the mach3 or fusion it seemed like although I was getting a beyond close shave, part of my face was being taken off along with the hair. I wouldn't get irriteted per-se, but my face would kinda sting if I tried to do touch-ups. sometimes I could see dead skin on the blades mixed in with the hair. I do not get this problem when using a stra8.
The angle on the mach3's doesn't look that bad, so why would it feel worse?
well, aside from each stroke counting as 3-5 passes depending on the number of blades (maybe I just answered my own question).
