@rostiger @tty Use a bowline whenever you want a knot to Not Move, i.e. the opposite of a slip knot. Also when you're trying to grab a closed circle or hole i.e. the opposite of a post or peg. Now i understand why this was useful in your (@tty) case.
@furiousgreencloud @tty It's one of my favorite and most practical knots I know.
