Abstract
Shaving head for a dry-shaver having an arched perforated cutter foil and a cooperating lower cutter resiliently urged into the foil. For cleaning purposes the lower cutter is rotatable about a longitudinal axis from the first position, in which its blade edges cooperate with the foil, to a second position in which the blade edges are accessible for cleaning, when the shaving head is removed from the shaver.
