ABSTRACT:
A collapsible handsaw which can be erected and collapsed without tools includes, in a first embodiment, a saw blade, a foldable frame, and a flexible binder. In this embodiment the frame includes two frame portions wherein each is connected by a pin to an opposite end of the saw blade and the single flexible binder is used to secure the free ends of the frame portions relative to one another when the handsaw is erected and ready for use and to secure the components of the handsaw in a bundle when the frame is collapsed. A second embodiment of the frame includes a pair of flexible binders and a third frame portion which, along with the first and second frame portions and the saw blade, forms a quadrilateral when the handsaw is erected and ready for use. The flexible binders can take various forms including elongated straps and flexible loops of fixed lengths. Free ends of elongated flexible binders are secured in different ways including by hook and loop fasteners and wedge configurations.
