When I see statements like this it really makes me wonder what someone is really thinking or not!! If you can get a BBS shave in 1 pass there would be no reason for a second, third, etc... You obviously can't get a BBS shave in 1 pass so why call it a 1 pass BBS shave? A BBS shave is of the entire portion of what your shave consists of, be that face, neck or head only or all the above... If you shave and can't acquire a BBS in all area's you shave then you haven't achieved BBS...its as simple as that!! If it takes more than 1 pass, then its not a 1 pass BBS shave!! Seems simple enough to me!!
