A rotary electric shaver includes an outer blade whose upper surface functions as annular shaving surfaces having multiple hair inlets formed therein, and an inner blade that has a small blade which rotates while coming into sliding contact with a lower surface of the outer blade. The small blade is formed so that an inner blade base plate is partially erected, and is disposed in at least two rows on a circumference close to an outer periphery and on a circumference close to an inner periphery. There is provided a movable inner blade that has a movable small blade which is vertically movable along a front end surface in a rotation direction of the small blade, with respect to the predetermined small blade.

A surgical hair clipper assembly includes a clipper body and a blade assembly connected to the clipper body. The blade assembly includes a moveable blade configured to reciprocate to remove hair from a skin area and a blade housing that houses the moveable blade. The blade housing has a guide surface that faces the skin area during a hair removal process. A suction attachment includes a clipper attachment connected to the clipper body and a nozzle structure connected to the clipper attachment and extending distally to an end. The end is located no more than about ten millimeters proximal of a plane defined by the guide surface.
