A rotary shaving head having a one-piece cup-shaped metal body including a comb portion. A plurality of openings in the comb portion are defined by opposed sidewalls, the intersection of at least one sidewall of at least one of the openings with an inner surface of the comb portion defining a cutting edge having a positive rake angle. A rotary shaving head manufacturing method includes the steps of etching a set of openings corresponding to a shaving head blank into an elongate flat metal strip, forming the blank into a cup-shaped unfinished shaving head, and removing material from the inner surface of the comb portion of the unfinished shaving head.
