Abstract
Two blades of the cutter blade assembly are pivotally mounted separately by means of a coupler on opposite sides of a drive shaft and move to an extended position by centrifugal force. Upon one blade striking an inseverable object both blades are caused to move to a retracted position. In moving from the extended position to the retracted position the impacted blade coacts with the opposite blade to move the latter to a retracted position.
