    • 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.
    • 本发明是一种轻便的可折叠手锯,用于露营,徒步旅行或其他方面。 锯破裂,并且可以固结成单个管状,其中所有部件都装配在管内。 在功能构造中,可以由具有不同直径的两个管状构件,锯片和紧固元件构造三角形锯。 或者,三角形锯和降压锯可以由具有不同直径的三个管状构件,锯片和紧固元件构成。 管状构件形成锯的框架并且容纳用于插入锯片的槽。 提供紧固元件以使锯具有必要的刚度并且在叶片上施加必要的张力。 此外,该装置可用于形成具有多个附属元件的篝火烹饪器具。
