I'm 23 and just started using safety razors, I actually enjoy shaving now and converted my dad and friends. I'm using a futur and always seem to have rough spots around my jaw. I have tried different blades and directions without no change. me and my dad both have thick and heavy beards, he has a r41 and loves it. I went ahead and ordered a r41 grande and a 39c to add to my collection. Will these help with my problem or am I doing something wrong?
