The rotary cutters cooperating with the two opposed cutting edges of the safety razor blade are enclosed by tubular guards in which longitudinal slots are provided leaving only a predetermined gap parallel to each of the cutting edges, the width of which can be varied to suit the closeness of shave a person desires, while also insuring safety of operation by positively limiting the extent of bulge of the skin between the adjacent rounded edge of the clamp that serves as a guard and the far edge of the slot in the tubular guard, the latter taking over completely the function heretofore served by the guard on the head of the conventional interchangeable blade safety razor. The split head of the razor permits easy assembling of the rotary cutters and their cooperating tubular metal or plastic guards and the guards can be clamped at their extreme ends in the two sections of the guard or can be secured by set screws in adjusted position, the screws being loosenable and tightenable from behind the guard portion of the razor head where they are out of the way completely.
