Related	Figure-of-eight knot, Figure-of-eight follow through, Figure-of-eight loop
Releasing	Can jam badly in any rope type, but somewhat less likely to jam than a figure-of-eight loop.
Typical use	Caving. Sometimes used instead of a figure-of-eight loop to attach a rope to an anchor point or belay. It has both greater strength and bulk than a figure-of-eight loop, so is normally used only in thin rope.
Caveat	None, secure.

The figure-of-nine loop is a type of knot. It is tied as a figure-of-eight loop but with an extra turn before finishing the knot - hence its name.
