Imagine having the brute strength of a chainsaw combined with the portability of a pocket knife. The Pocket Chainsaw is exactly that. Used by the U.S. military, this fully capable saw fits curled up in a small tin and weighs only 5 ounces. Its 124 bi-directional teeth made of high strength, heat-treated steal cut easily through tree limbs and more. This tool is perfect for campers, surivivalists, and dads who want to complete their weekend yardwork with a little extra vigor.
