Abstract
There is provided a reciprocating saw blade having a tapered tang stem. The tang has a tang portion with at least three outer edges and a stem portion with at least three outer edges. The profiles of the tang portion and particularly the stem portion are such that they facilitate the effective and efficient engagement of the saw blade with any of numerous different keyed or keyless chucks of reciprocating saws. The tang/stem profile also advantageously provides for increased strength for resisting failure and/or fatigue stemming from a cutting force applied to the saw blade during use.
