The pocket Chain Saw is a great addition to any survival kit. It features 124 bi-directional, heat treated steel cutting teeth that cut on both the upstroke and the down stroke. Also, since it is flexible, it wraps around the wood on three sides increasing its efficiency. In a survival situation, this saw is safer than an axe or power chain saw since it won't bounce off a log into a leg or foot. By attaching a cordage to each end, it can cut limbs in hard to reach places. It stores in a small metal can about the size of a small shoeshine tin and easily fits in a shirt pocket. Dimensions: 28' long. Wt. 5 oz.
