Alpine Butterfly Knot and The Trucker's Hitch

http://www.survivalnewsonline.com/ind... Use the Trucker's Hitch to gain mechanical advantage. Use the Alpine Butterfly instead of an overhand loop if you want to use the rope again when you're done. NOTE: In the video I state that it's a 2:1 mechanical advantage, when in fact it's a 3:1 mechanical advantage (at least with respect to the standing part of the rope). See this article for an explanation: http://www.survivalnewsonline.com/ind...
