ABSTRACT:
A reciprocating saw (11) comprises a support (27) attached to the body of the saw and a shoe (25) pivotally attached to the support (27). The pivoted shoe (25) enables the shoe (25) and thus the blade to engage a workpiece at varying angles during cutting. The shoe (25) is attached to the support (27) by a hinge. The hinge (12) comprises a spaced pair of tabs (29,31) extending from the support (27) and located between a spaced pair of tabs (45,47) extending from the shoe (25). Each of the support tabs is paired respectively with one of the shoe tabs. Pins (55,57) extends through apertures (33,35,49,51) in the tabs (29,31,45,47) and forms the hinge pivot. The hinge pivot is maintained in place by spacers (59,61) located, respectively, between each pair of shoe and support tabs and press fitted to the pin. The press fitted hinge (12) is low in cost and is durable.
