The trimming device has a blade driven by a shaft to have each end pass over cutting teeth at the forward edge of a circular cutting plate. The drive mechanism may be a belt or a gear train driven by a motor which is mounted on a frame to which a top and bottom plate is secured. A housing encloses the drive mechanism having a handle containing a switch and a receptacle for the prongs on a plug-in cord.
