Abstract
A reciprocating (saber) saw blade having normal cutting teeth for most of its working length from the tip towards the connection end.
Opposed downward cutting teeth extend the remainder of the working length, and are angled forward in the direction of the cut. These downward cutting teeth cut a wedge-shaped notch in the workpiece at the end of the downward blade stroke. This notch enables the subsequent upward cutting stroke to progress forward without splintering surface fibers
