This knot is truly wonderful :
1. The segments cross each other at the optimum, the right angle, so the saddle-shaped local deformations around the areas of mutual contact are maximized, and the lines do not run the danger of sliding easily on their sleek surfaces.
2. The cross section is reasonably wide : assuming that the lines follow an orthogonal grid, around four rope diameters.
3. The pattern of the 2D tying diagram does not differ much from the pattern of the tighten 3D knot - a rare great advantage regarding the learning, memorizing, remembering, tying and inspecting the knot.
4. This pattern is the most simple possible : an alternating orthogonal grid, where the lines of the one link lie in between the lines of the other. See the "yellow" or "light", and the blue" or "dark" lines of the knot as shown in the attached pictures.
5. It is side-symmetric, just like the Zeppelin bend : the flat surfaces are symmetric, so one picture or mental image of it is sufficient to describe it completely.
6. It is very easy to untie, again just like the Zeppelin bend, and all the bends where the lines play the role of "pivots" in a nub resembling a rope-made hinge mechanism.
7. Although I had not the means to test it on slippery material, I believe that even if the Standing and the Tail ends are swapped, the bend would be equally - and perhaps even more - secure.
8. As the links are topologically equivalent to the unknot, it can serve as a PET eye-knot, and/or an end-to-middle knot.
9. The Tails run parallel to the Standing Ends, an advantage in many practical applications, which also makes this bend, although based on a flattish, textile-like pattern, look streamlined.
10. Although we can not just pull the free ends and wait the knot to become tighten all along its nub and compact ( there is too much inner friction, and the tensile forces are absorbed before they reach the Tail ends ), we can nevertheless dress it easily and properly, with a trick : we can first push the one collar towards the other, and take the remaining slack only afterwards, by pulling various pairs of opposite ends. Doing this two or three times in a row, the knot almost self-dresses itself : it becomes very compact, and settles in a very symmetric form, with all the lines parallel or perpendicular to each other.
I am sure that if one examines this knot a little more, he/she will discover many more advantages - because it seems that this classic warps-and-wefts pattern has many more aces in its nub.
