Those knots that have one or more parts that lie diagonally over another are

collectively known as crossing knots. A characteristic of many is that they may
tied either with a working end or in the bight. They are often hitches, used to

attach a line to a ring, spar, rail, post, stanchion, or to another rope. When a loop
is knotted into a running (adjustable) noose, and that noose is of the slide-and-

grip variety, it will sometimes be seen that it has been made possible because of
a crossing knot.
