New fishing knot variation: w/ how to video

[xarax]

Very interesting idea ! A Gordian-knot-like mechanism, where the mere presence of the volume of a stopper ( in this case, of the overhand knot ) or of any other knotted structure ( be it topologically equivalent to the unknot, or not ) works as an obstacle, which prevents slippage. I am not a fisherman ( not any more… :)), so I am not qualified to answer your questions. However, I have recently used a similar idea in a more complex TIB English knot :

You can replace the overhand knot with any other stopper - but I believe that you need a TIB stopper, so you can insert it in any point of the main braided line you wish, without having to tuck the whole line, with its leaders and hooks, through the bight… Now, the problem with those stoppers is that they are much bulkier than you wish them to be…
If you can not tie an overhand or any other non-TIB stopper, and you do not want a much bulkier TIB stopper, you can always use a humble nipping loop, which can work in the same way : as an obstacle. In fact, that is the way it works in the case of the bowline : As an anchor at some point of the Standing part, on which we can attach the returning eyeleg. The inner friction of this anchor prevents it from “walking” down, towards the tip of the eye.

This idea reminds me of a few things mentioned at the thread about the “What is a knot” question :

knots do not need to “use” their topology or friction to remain untied. The mere existence of the volume of a knotted segment of a rope, due to the bulk of the ropes themselves, can prevent it from slipping through a sufficiently narrow loop - even if there is minimal friction involved, or no friction at all. In such a case, a knotted part of a knot should perhaps be considered as a stopper sub-knot into the knot, a stopper that can not move freely inside the rest of the knot s nub.

there might be parts of a knot which serve in its working, without themselves be tensioned, i.e. , by their mere bulk, the volume of the rope material they contain. ( Rope is flexible, but not compressible). In other words, those parts may be considered as stoppers within the knot they belong, that prevent the slippage… by the same Gordian knot/link mechanism : A knotted sub-knot can not pass through a sufficiently narrow loop.

Until now, I believed that the bulk of an area of a knot, ( which we can easily increase, by retuckings, for example, or by retraced or double line paths ), can only serve as a means to obtain greater first curves, by forcing the standing part to encircle this area - and as a “cushion”, able to absorb dynamic loadings. Now, I believe I can also “see” better how the mere volume of a section of a knot is an obstacle that can prevent this part of the knot move/slip through the same, or through another knot. This function of volume in knotting may sound obvious to many people, but I had not realised it so clearly as I think I have now.
