Yes, I know…It was just a temporary label, because I, too, had not any inspiration for a proper name… :). I do not even like the “double overhand knot” name, for a shape “8” like knot…
Even a “simple” double collar structure on the working end (“simpler” than the more twisted/convoluted one shown at Reply#27, (1) ) - can be linked within the helical nipping structure on the standing part in a sufficiently secure way. ( See the attached pictures for a most simple helical loop.)
This indicates two things :
- That the nipping loop on the standing part is a very efficient mechanism of gripping the legs of the collar - even if this loop is not a closed ring, but a single open helical coil.
- That the double collar on the working end is a very efficient mechaism of distributing the tensile forces on the standing part - even if this double collar is nothing more than a simple “S” form.
