you lay out two loops; the left loop is a "6" and the right loop is a "9".
The bitter end ...
Um, let's *check* that term : it should denote the "end" as in
"side" / "half" / "part" (i.e., that bunch o' rope over there...)
of a line at the bits
--and not some *ultimate*/absolute end-of-ends point (which
is, sadly, the vogue use of it by those ignoring the history).
As we still use bitts, it seems worth fighting to preserve and
continue the historical sense of this term, and not to stoop
to commoners' parlance who come without nautical seasoning.
In the knot I am trying to describe, you lay out the "6" as before, but instead of a "9" you reverse the direction of the loop, making it counter-clockwise
Whoa : flowing down the line into the '6' or '9' takes one
into an anti-clockwise rotation (towards the tail, into the
knot from the to-be-tensioned SPart). (You must be seeing
the movement going the opposite way.)
In either case, though, in the zeppelin
and several other
end-2-end knots, the SParts turn
such that they rotate the same way (and so give a quite sure
grip and twist to the nipped parts --unlike the butterfly,
... have a mirror image "9". How am I doing?
On explanation, fine ; on reading my reply, maybe not-so-good :
I described this knot, which as noted is one brought up previously
(and accidentally/mistakenly, in some cases, for the zeppelin
you come out with a perfectly symmetrical knot, viewed from either side (front or back). The regular zeppelin is not the same on the front as on the back.
I will leave it to others to indulge the nature of symmetry,
but suffice it to say I regard both as such ; the z.
quality of looking the same from *top* & *bottom* (in the
sense of in each case one SPart's collar goes under and the
other's over, and so on).
Also, the knot you describe is superfically like SmitHunter's bend
(but that knot's overhands
---the sage was right---a picture is worth at least a thousand words...
Hardly : one needs closer attention to language use, and not
dismiss it or take it cavalierly ; it should
work, but it takes
some work & discipline to keep this tool sharp --such as slapping
away degradation & abuse.
