Hi Alan

Having tied this structure before, i think of it as the simplest one of helical adjustable eyeknots (reply#14).

And here comes the good part....

If you unbend Spart's helical curvature (straighten the helical coil), you will transform it into Xarax's constrictor noose (or buntline extinguisher  ;)) and vice versa.

BUT we must ask :: what is the point of such a knot,
an "adjustable" eye knot?!  Unlike with some friction-gripping
*fixed* eye, where the eye size in indefinitely large,
these knots are tied with a maximum that can only
be diminished, tightened down --unless a long length
is left for enlarging.  And tightening under load might
be problematic re stability/structure or just plain
limited by force & friction.

In my experience it is harder to make a very strong friction-gripping knot where the loop is adjustable by moving the gripping part along the standing part than it is to make a knot where the loop is adjustable via the working part.

Yes, tightening under load might be problematic, and untying, too.

One application of adjustable loops is to secure loads, but I think Trucker's hitch variations are more suitable for that in many cases.

           Hi All,  I have two loops here, can handed heavy load and easy to untie.
                      Hope  you like it.  谢谢 alanleeknots.

Do you think there is some advantage in the more complicated version 2 over version 1?

...
The insertion of the WE through this configuration, leads to a non slip, figure 9 based adjustable eyeknot, as shown in the next two images.
...

Funnily it looks literally like figure 8 in the first image and reminds of Hunter's Bend in the third one. I learned to tie it my eyes closed.

Interesting this figure 9 geometry can transform to a loop, kind of a Non TIB false Butterfly knot ,
see the photo below,  I think there is  a interlock overhand knot bend or loop, is somewhere in Ashley knot book.

I think so too, version 2 is more stable and compact. 谢谢 alanleeknots.

Thank you Alan, a very nice pedestrian loop almost a lanyard knot.
Don't look at the Sun.

#1452, and Ashley has it as a lanyard knot,
#782 IIRC (or nearby).

Well, I think version 1 is more compact and the additional twist in version 2 is not needed.

Indeed, this is a simple effective eye knot,
samples of which I've encountered in commercial
fishing gear around Cape May, New Jersey, USA.
In some materials, it has the nice property of
lightly jamming, though commercial fishers tend
to lock things down with "hog rings" or black plastic
"electrical" tape (very seldom have I seen whipping!?).

For many materials, one is better off putting in one
more tail wrap, getting 3dia for the nipping turn
to compress, and surer security-when-slack binding
of the tail wraps against the SPart  (but I'm still not
entirely confident with it for e.g. firm kernmantle in
life-safety uses,  left untended).
