Nothing really special about that picture. Have seen much better ones. No offense to whoever that is, It looks great. I am just saying that is nothing really radical or that short. Im really not sure how short you can go. I think it depends on a few things. if you have large knots, it will start to look funny once u really get short short. I am thinking of taking an old piece and experimenting and buzzing it down shorter and shorter and see how far we can actually go. I think the shortest I have seen on the forums so far is an inch long or a little shorter than an inch. my guess is that MAYBE u can get down to half an inch. any shorter, I really have no idea whats gonna happen. Would be interesting if someone had an injected skin or some kind of single hair ventilation and tried to cut it almost like a crew cut.
