At the risk of violating the old maxim
Where ignorance is bliss,
'tis folly to be wise, this post begs some obvious questions and redress.
ABOK #1408 appears to be somewhat related to the Zeppelin Bend's design--if you do not cross the tails as shown in the diagram. What do you think of this ABOK #1408?
You have a good eye; but this version/dressing of #1408 doesn't
perform all so well, as it both worryingly sucks in tail and rolls out
material in some slippage, and in doing so makes its
collars tight,
so loses the very aspect that a properly dressed #1408 is to provide.
With the correct dressing, the collars have an openness like that
of Rosendahl's bend, and the knot loosens easily.
To my eye, it looks much more like a minor variation on the so-called Ashley Bend.
Indeed it has much similarity to #1452, with the interlocking of the SParts
and nipping of tails brought together up through the SParts' joint nip.
"So-called" "Ashley's Bend" comes from CLDay, a friend, and has been
adopted by the echo chamber thereafter. As it's not his only end-2-end
knot, I usually follow the moniker with the number (and might sometimes
have another number, for some other of his knots). And "Zeppelin" (not
sure re "bend" vs. "knot") comes apparently from some magazine-article
authors (or even merely a headline writer!), with no apparent competing,
original name (unless that interviewed subordinate referred to it by
"Rosendahl" ?).
1409: But in this second form it is one of the least secure knots known, its only rival being the Whatnot. The change from one of its forms to the other may occur accidentally or intentionally. So the knot is quite untrustworthy.
One might wonder at "intentionally" ! As for security, I've just put some serious
load on a couple ropes with this dubious version and had it hold -- rather hard
and slick PP, kernmantle (monofilament) & laid. In shock cord --ha!-- it hardly
slows down (spilling), giving a lot of torque to the feeding-out material.
--as you note:
Tying this in more elastic material, you get a dramatic demonstration of what Ashley is talking about. It rolls apart.
But this is a non sequitur:
So it becomes quickly evident why 1408 and its shifted form in 1409 are neglected.
Much/most of
ABOK is neglected --surprisingly, to my mind, Ashley's
stopper--, and one can only wonder why (even if good reasons exist).
This has implications for the Ashley Bend that I did not consider before. It is a very easy error to mistie the Ashley Bend and get the scary 1408/1409! They even look like the Ashley Bend. For 1408/1409, the "q" initially goes through the "b" from above. For the Ashley Bend, the "q" initially goes through the "b" from below.
WOW, so easy to do this, huh!!! But doesn't this fear also d-q your Zepper?
Poor Ashley; getting his name tacked to a bend in a way he might not appreciate, especially considering this relationship.
Maybe the modern detection devices can check whether
he's turned over in his grave. (But then would we know it
was over
this fear?)
