Abstract

A hand-guided power jigsaw (10) having a jigsaw blade (33) which can be detachably clamped between the free ends (53, 54) of two essentially parallel-arms (221, 222) that are preferably comprised of a U-shaped frame (22), in particular comprised of a tube, and which can be driven, in particular in a reciprocating manner, by a motor built into the jigsaw (10), wherein a laterally protruding handle (13) with a switch button (15) is disposed on the front of the free end of one of the arms (221, 222), is particularly maneuverable and easy to produce since the lower arm (221) has a, base housing (12) attached to it, which is embodied in the form of a pistol and protruding obliquely back and down from underneath the housing (12), has a handle (13) whose rear contour toward the base housing (12) forms a curved, angled throat (14), which rests in the hand of the user in a horizontally and vertically supported fashion.
