Alan, your knot is an old one to me! But I think you
show the tail too straight --it should be moved into
slight curvature as the rest of the knot grips it all
along its tuck. The
quick8 can be seen as such a knot,
the simple passage of tail through
fig.8 surprisingly secure
under load (and a backflipping tuck between eye legs
is not only sure security but at least in flexible cordage
a way to gain slack-security. (And it was a structure
I'd fiddled a number of times
en route to putting in
a bowlinesque collar, not realizing that one could stop
at that point and ... it would hold!)
And per the popular orientation qua stopper/eyeknot,
we must call this knot base a
"reverse" fig.9.
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.
This is an alternative geometry,
of your V1 figure 9 based nipping structure,
In the top orientation, rotate the leftside's turn
down around the upper part of right side
and similarly move the right side down the left,
and collapse the diagonal part shared between them.
THIS is another
symmetric-fig.9 form,
and makes for some nice eye knots,
and for a nipping of the tail between turns
such as you do.
Beware cases where the returning eye leg might
be isolated in loading, as it can slip out, then.
The structure is akin to
#1425, with those overhands
continued into fig.9s. There are lots of interesting
uses of it, e.g., as a re-tucked
overhand in making
a noose hitch.
