Bight (knot) be used in situations where the ends of the rope are inaccessible, such as forming a fixed loop in the middle of a long climbing rope. Many knots normally tied with an end also have a form which is tied in the bight (for example, the bowline and the bowline on a bight). In other cases, a knot being tied in the bight is a matter of the method of tying rather than a difference in the completed form of the knot. For example, the clove hitch can be made "in the bight" if it is being slipped over the
Bowline on a bight a climbing harness by tying a regular bowline knot and then re-threading it, such as is done with a figure eight knot. However, it is "critical" to use a strong backup knot with plenty of tail beyond the knot, as the knot may untie during long climbs. The advantage of using this knot instead of the figure eight knot is that it can be easily untied after a severe fall. The bight of rope is initially used to make a bowline in the usual way (picture on right). However, the bowline is "not" completed by going on round the standing
