The other day I was untying a knot and happened upon this one.
Be careful where you go --knots curiosity/exploration can lead
to many deep places, with unclear return!

... it's basically the Manharness Knot tied to be slippery.
However, I then realized, that by tying in this way near the end of the rope
and then collapsing it,
You realized this? --or did the knot, wrong-sidedly loaded,
manifest the collapsed structure for you?
For the named knot is apparently to be used in series,
with both ends loaded, and should otherwise be loaded
in the
opposite (reverse) way, which should not capsize
(as the SPart will flow into a sort of
crossing-knot form
rather than an unbraced
half-hitch/turn ).
Well, here's what I just *realized* : if one reeves the eye
through the slip-bight and draws down the slip-bight, then
one prevents the capsizing/transformation of the original
into the novel, and has a sort of nicely secure
*bowline*(which is morEasily TIB (Tied Inthe Bight) than by reeving,
so that's unhelpful to rockclimber tying in, alas). !?
And this structure lends itself as a *seed* for growing further
novelties through knotSpacExploration --ELFEKS abound !!
(But do they astound?)
[ELFEKS = empirically less-frequently encountered knotted structures --PvdG]
... it changes both the knot and its uses :
instead of a fairly weak loop designed to be tied in the middle of a rope,
it creates a very sturdy loop for the end of a rope
which no matter how much strain is put on it, it is very easy to untie.
One can question your assertions of strength, but note my remark
about the (correct or better) orientation of the original --I don't think
that one will be so "weak". The collapsed knot does seem very easily
loosened --indeed, it seems hard to stay in shape, in some springy,
kernmantle PP marine cord (tends to flatten) I'm fiddling with, now!
As for strength, though, I'm less confident of any gain, there. And
we might conjecture that there could even be slippage of the *knotting*
down around the merely slightly helical (YMMV w/setting) SPart.
So, is this a new knot, or does this knot already exist?
If the latter is true, what is it's name?
Bit of a non sequitur implication re nomination : existence doesn't
imply naming. I'll surmise that no one has thought to give the
structure life as a valid entity, even if others have come across it.
(E.g., the initial slip-bight now serves what purpose? --it doesn't
even seem to give
helpful bulk (to soften SPart's bending, i.e.)
to the knot, and offers a potentially snagging, misleading eye.)

Thanks for that clarity (though as stated elsewhere, black and thin
cord isn't as good a material for illustration as something firmer
that shows shadow). These images are amply clear, though.
Thanks, Carson,
