I been shaving with a St8 for about a year I have a DOVO 5/8 and a Begnal I can't remember the size but I been having a hard time shaving underneath the jaw line I do a normal shave then an X shave then Agaisnt the Grain but it somtimes it feels very bumpy when I under the jaw line. I was hoping if you guys gave certian techniques in shaving underneath the jaw line that is the only place I can't get it right.
