Question.

My beard usually grows in pretty quick, and the only time that my face stays BBS for a long time is when I used a multi-blade cartridge razor that did the old 'pull and cut below the skinline' shave. Well, I'm progressing to ATG on my straight shaves and after a whole day i'm still BBS on my cheeks.
So here is where I'm confused. I'f a straight razor does not pull the hair and cut below the skin, how is it still smooth? Cause it should have already grown back by now?
