Abstract
A reciprocating cutter incorporating at least one saw blade and being optionally provided with a cooperating guard. The guard provides a protective cover for the blade or blades of the cutter and, through a spring-loaded biasing thereof, cooperates with the cutter to both stabilize the blade or blades and the workpiece and provide a degree of control for the movement of the cutter through the workpiece. The cutter, which may utilize a single reciprocating blade with which a spring-biased guard cooperates, in most instances will comprise a pair of alternately reciprocating blades, the teeth of which are selectively set to define a single clean kerf in the workpiece. The blade or blades can comprise the sole cutting device in a hand-held motor-driven implement, or alternatively can constitute an attachment, either permanent or removable, for a hand-held motor-driven hedge trimmer incorporating reciprocating trimmer blades to which the saw blades will be operably joined for simultaneous reciprocation therewith.
