The strangle knot starts with a round turn and the end is stuck under two parts. It may be used to tie up a roll. It can only be tied around a cylindrical shape. If required, a loop may be stuck instead of the end, which makes a slipped knot that is one of the best for tying up sacks and meal bags. With one or two additional turns the strangle knot makes an excellent temporary whipping for the end of a rope.
