ABSTRACT:
A portable, cordless, electrically energized grass trimming device is disclosed having a rotary cutter blade which is formed of a flexible strip of material and which is mounted for rotation over a predetermined course. A blade stabilizing means is provided for restraining the blade along a segment of its length for maintaining rotary motion of the blade in the predetermined course upon impact with other objects. The flexibility of the blade is enhanced by mounting the blade for rotation over a course described by a curved surface of revolution and blade durability is improved by providing a means for absorbing impact shock when the blade strikes an object. An improved blade is described having integrally formed resilient means for absorbing the shock of impact.
