A selectively adjustable air deflecting damper is provided in the air exhaust barrel of an electrically heated hand-held hair drier for adjusting the area of the air discharge orifice and concomitantly the air velocity of the heated air discharge. The damper is pivoted in the barrel downstream of the air heating element and is selectively movable between first and second positions providing maximum and minimum effective orifice openings for producing a dispersed and a concentrated air flow, respectively. The damper is spring biased to its first position and operated by a trigger arranged for actuation by a digit of the hand holding the hair drier during use.

To facilitate the cleaning of a can opener cutter, the pivoted handle on which it is mounted is arranged for easy removal. The shaft on which the handle is pivoted has an undercut section. A keeper edge mates with the undercut section of the shaft to restrain axial motion of the shaft without inhibiting rotational motion. The inner end of the shaft cams the keeper aside to permit assembly. Although a gravity system could be used, the keeper is normally spring biased towards engagement with the undercut section of the shaft. The keeper and biasing element may constitute a single element. When a spring biased keeper is used, the shaft has a chordal segment removed between the inner end and the undercut section. Thus when the shaft is in a predetermined angular orientation, with respect to the keeper, the handle may be removed without camming the keeper aside.
