Abstract
A bow saw having a frame and a saw blade which is tightened between the opposite ends of the frame when used. The frame is composed of three individual elements which are interconnected by means of simple and cheap connections and which are firmly held together as long as a tensile stress is maintained in the blade by means of screw members. These elements are collapsible in order to reduce the size of the saw. To this end a main element has a cavity for housing the blade, while two end elements have cavities allowing the main element to be partially introduced therein.
