Whoa, not to discourage the video,
but this isn't so tricky a matter, at least on the basic question.
You presented an image of a knot--in a way, a sort of
cookie-cutterimage showing
just the "nub" (a Dick Chisholm term) of the knot.
Two parts run off the top of the photo, two off the bottom.So, what is it?
Well, you told us it is a loopknot. Fine,
where is the eye--top or bottom?And, opposite the eye,
which of the two ("twin") ends should be loaded?(Either might be--the usual case with such things going unspecified,
and maybe well enough, with no great difference, but ...)
So, it's a simple top/bottom & left/right question, and that's hardly technical.
- - - - - - - - - - - -I did touch on a philosophical/conceptual issue regarding how one might
define "loopknot", in remarking "or not" about there being an eye at all.
From the perspective of this "nub", there is--for a loaded such "loopknot"--
a set of relative tensions on certain ends. For a bend it would be 100% & 0%
opposite the same (2 SParts loaded, two corresponding ends not); for a
loopknot it would be 50% & 50% opposing 100% & 0%. And my remark
was an allusion to the thought that this would be the
essential definition
of a loopknot--i.p., nothing about there being an acutal eye!! That of course
seems odd, but there is no effect on the
nub at least--it behaves according
to the various tensions.
An example I like to mull over is tying a tow line to one side of a barge,
and then bringing a second, similar (short) line from the other side and
tying into the tow line in the manner of a Bowline. From the same sort of
cookie-cutter perspective looking at the nub, but for perhaps distinctively
different ropes involved, one would see a
bowline's body.
In your case, one can imagine the eye being either top or bottom, and
I so discussed that a little. And, with the particular general shape (i.e.,
the "Fig.9", I revealed that with some playing around one can put it
into either of two symmetric forms. Ashley's #1425 (not -a) can be
seen as an abbreviated bend in this form, where the ends each stop
short of completing its trace (they trace part way then stop). There are
some nice loopknots in which the SPart makes the full form and the
end makes the 1425-like partial return: apparently strong, secure
when slack, fairly easy to untie after loading, and TIB (tiable in-the bight).
But, again, top/bottom, left/right are simple questions/answers, for starters.
