Abstract
Abstract A tweezer useful for plucking hair comprising a housing; arms extending out of the housing and having jaws for grasping a hair to be plucked; first means for closing the arms around the hair until the hair is grasped between the jaws; second means for automatically retracting the arms into the housing after the hair has been grasped between the jaws; means mounted for movement along the housing, whereby a first movement thereof causes the first means to close the arms around and grasp the hair between the jaws, and a second movement thereof, in the same direction as the first movement, causes the second means to retract the arms into the housing, thereby plucking the hair; and means for automatically returning the arms to their unretracted and unclosed position.
