Eskimo bowline structure of the knot was not identified by Clifford Ashley (in 1944). All of the maneuvers to tie this knot are generally in the opposite (or 'anti' direction) relative to the bowline. Dan Lehman regards the general, bowline-like structure as an 'anti-bowline' in the sense of "anti-clockwise": in that with regard to the main nipping loop, the tail on returning from forming the eye is brought through this loop in the opposite direction relative to what is done for a bowline. When this knot is ring-loaded – and the knot effectively becomes an end-to-end knot – it is effectively a
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
