An electric shaver has a housing which contains a motor. An inner blade support is mounted for rotation on the motor at one end of the housing, and an outer blade on the housing covers the inner blade support. Inner blades on the inner blade support revolve and are urged by springs against the outer blade, whereby hair extending through holes in the outer blade is cut by the inner blade. Openings through the inner blade support permit cut hair to drop therethrough, and the hair collects in a receptacle below the openings. Air flow caused by revolving the inner blade and other members on the inner blade support blows through the openings then near the receptacle to move hair from between the inner blade and the outer blade to the receptacle. The air flow then continues out of the housing through exhaust openings in the periphery of the outer blade. The air flowing from the openings is divided into two subcurrents flowing in two paths, a first path through the lower region of the area below the inner blade support and the second path through the upper region of the area below the inner blade support to decrease the volume and velocity of the air flow passing near the receptacle for preventing the air flow from moving hair from the receptacle out of the exhaust openings. A chamber is formed on the top surface of the inner blade support about each opening to trap cut hair there so that most hair will be directed through the openings. Arcuate slots near the edge of the inner blade support direct undesired centrifugal air flow downward and allow hair on the top of the support to fall to the receptacle. A rib that forms the forward wall of each chamber and each inner blade extend at angles to radii on the inner blade support intersecting the rib and the blade respectively to decrease air flow outward along the inner blade support.
