US 6,298,564 B1 · Portable hand saw

Abstract

The present invention is a lightweight collapsible hand saw for use when camping, hiking or otherwise. The saw breaks down and can be consolidated into a single tubular shape, with all of the components fitting inside the tube. In the functional configuration, a triangular saw may be constructed out of two tubular members having different diameters, a saw blade and a tightening element. Alternatively, both a triangular saw and a buck saw may be constructed out of three tubular members having different diameters, a saw blade and a tightening element. The tubular members form the frame of the saw and contain slots for inserting the saw blade. The tightening element is provided to give the saw the necessary rigidity and impart the necessary tension on the blade. In addition, the apparatus can be used to form a campfire cooking utensil with a number of accessorising elements.
