How to tie an alpine butterfly knot
The alpine butterfly knot - also known as the trucker's hitch - is excellent for cinching a load, by forming this knot then running the standing end around an anchor, back through the eye, and drawing down you can pull the working end taut and after untying the load the knot is easy to remove.
The knot is also often formed by wrapping the line around the hand loosely three times then crossing the outer line over the other two and the second line over the first and the first crossed line then through the palm.
