The invention pertains to a saw, in particular to a jig saw or scroll saw, with a saw blade which is driven by a force acting on a parallelogram of rods. A saw blade is attached to a connecting shank which joins two longitudinal side arms. The two longitudinal side arms are designed to move in their longitudinal direction. On at least one of the two longitudinal side arms a guide element in the form of, for example, a turning roller, is positively guided against a stationary guide surface which is at an angle, preferablye an acute angle, to the connecting shank. As a result of this positive guidance, the backward movement of the saw blade from the cut edge during the return stroke is reduced to a desired value. Thus a jig saw of small size, but with a large stroke, can be realized in which the saw blade is guided parallel to the cut edge at all times but is moved back by a small amount from the cut edge during the return stroke.
