Well, not that new.
I have always used some variation of wet shaving, but recently returned to using a DE (Merkur HD and Progress) with brush, cream, etc.
It's funny to read the instructional postings here and learn what I have been doing wrong for 40 years
What has been most interesting (and a little confusing) is the grain thing. For my entire adult life (I'm 54), I have been shaving my cheeks N-S and my neck S-N. The latter seems to equate to ATG on my neck. To confirm, I feel more stubble rubbing S-N than I do rubbing N-S.
I find it extremely unusual to shave N-S on my neck, and especially on the bottom of my chin. I have a goatee, so I'm pretty careful in that area anyway. I have never had any problems shaving ATG on my neck - it's harder for me to shave WTG there. Old habits, I guess. Am I the only one who did it this way before being exposed to the "right" way?
