Used to attach a rope to a log, or where security is not an issue. This
knot tightens under strain, but comes undone extremely easily when the
rope is slack.
Wrap the rope around the log, then pass the running end around the standing
part of the rope. Finally twist the running end around itself three
or four times. (Note: this is only shown twice in the animation.)
Tip: Jolly useful for dragging logs back to the camp fire!
