Bowline on a bight Bowline on a bight The Bowline on a bight is a knot which makes a pair of fixed-size loops in the middle of a rope. Its advantage is that it is reasonably easy to untie after being exposed to a strain. This knot can replace the figure-eight knot when tying into a climbing harness. However, it is critical to use a strong backup knot with plenty of tail beyond the knot. 2011 testing shows that the knot might slip when only one loop is loaded. Cavers and canyoneers ought to fasten their cow-tail carabiner through both loops. European cavers widely
The 85 Ways to Tie a Tie described in the book, in order of size, are as follows. Terminal sequences (the final three moves that end in the tying of the knot) are in bold. The knots are sometimes designated by their number alone (e.g., FM2 for the four-in-hand, with "FM" standing for Fink-Mao). A knot is self-releasing if, when the thin end is pulled out through the knot, no knot is left; as all knots start on the left, a knot is self-releasing if the terminal sequence is Ro Li Co; it is "not" self-releasing if the terminal sequence is Lo Ri Co.
