The stabilizing handle extends substantially transversely to the axis of rotation. The circular cutting blade may be a replaceable cutting blade or it may be integral with the shaft. The extension of the stabilizing handle may include a pivot and the gripping section if the stabilizing handle may include a hand guard.
