Just purchased my new Dovo razor, from manufactures which said shave ready. Had my first shave, no nicks! but feel it dragged a bit and had previously failed the hair test. Used my Norton 4/8 stone to hone it and think i have made things worse. As it is still a new blade and i have been careful not to apply to much pressure, how many passes on the 4 grit should be enough assuming i am performing the correct technique? Then how many passes on the 8?
