Originally developed for the military, CountyComm Grappling Hooks are used by soldiers in desert warfare to snag trip wires and tear down phone lines. While you may not be walking through a minefield anytime soon, you can easily pull down loose tree limbs and other hard-to-reach objects with a handy, collapsible grappling hook. Be forewarned, however: these hooks will not support your body weight and should not be used for climbing or other self-hoisting applications.
