essential piece of survival equipment Great for the Outdoors. A saw is an essential piece of survival equipment. The longer the saw, the easier to use, but the harder to carry. We achieved a nice balance between the two. The Folding Saw has a 8.25 blade of hardened and tempered steel that makes short order of branches, small logs, and brush. A comfortable handle helps to cut deep and true on each and every pull stroke. The extremely sharp teeth are differentially tempered for long life and work on green as well as hard wood.
