<p>The present invention provides a blade clamp for an electrically powered reciprocating saw. The clamp is arranged to eliminate, or at least reduce, misalignment of a blade during use with the cut direction and the longitudinal axis of a jigsaw. Thus, so-called "crabbing" of the jigsaw can be reduced, thereby increasing 5 the accuracy with which an operator can use the jigsaw. This is achieved by modifying the blade retaining pin such that it comprises a radial protrusion which engages with or locates in a cooperating groove disposed on the clamp body. Arranging the groove and protrusion to have an engagement surface (as opposed to a point of contact) further improves on lateral stability of the pin with respect to a 10 reciprocating shaft of the saw.
