Shock-testing the zeppelin loop seems like it would be a necessary step in that knot becoming an accepted tie-in knot.
There is nothing that would be relieved by such a test ! The
first overhand knot ( the one tied on the Standing Part ), which will be too tightly locked around the second knot, will not open up, and the
second overhand knot, which is nipped and locked by the first, although itself does not nip and does not lock it ( so, it does not contribute in the security of the knot ), will not close any more ! The
imbalance of the two parts, regarding their contribution to the security of the whole knot, will be maintained, and it will probably be amplified as well.
If the mere property that a knot just does not slip during shock-pulling would be enough to be "
accepted as a tie-in knot", each and every ugly tangly composed by overhand knots tied upon overhand knots, fig.8 knots tied upon fig.8 knots, and half hitches tied upon half hitches, would be fine ! In particular, each and every interlocked-overhand-knot bend blindly turned into an eyeknot by this ingenious "paste" way, would be sufficient, because it will not slip... There are dozens of dozens such bends that will not slip - so, their corresponding eyeknots will not slip, too, because eyeknots are more "secure", in this sense, than bends. And there are dozens of dozens bowline-like loops that are much easier to tie and to untie, that will not slip either - why on Earth one would like to test one particular more difficult to tie and to untie knot, and not all the others, is beyond my understanding. Perhaps the attraction of this fake Zeppelin knot, the so-called "Zeppelin loop" to some people, is due to the mesmerizing, indeed
hypnotic effect of the
Zzzz ...zzz...zzz consonant, repeated over and over again.
The
real Zeppelin knot, the Zeppelin bend, is a marvellous, almost unique bend, which does not work as most of the other bends we know. It is a
rope-made hinge, and the security and easiness with which it can be untied even after hard loading is based on this fact. People that learn knots only by reading
knot books and memorizing
knot recipes were astonished, because it was not easy for them to
understand how it works - and it was not included in their Bible of knots, the ABoK. So, they made the ingenious thought to use it as an eyeknot, too, so they would be able to kill both birds with the same bullet... Mis-using the Zeppelin knot this bad way reveals two things : First, that the person who does this has not understood how the true, genuine Zeppelin-like knot, the Zeppelin bend, works, so he does not understand that this imposter is NOT a Zeppelin knot ( For Zeppelin-like loops, see, among others, (1)). Second, that the person who does this has not understood how the bowline works, he does not trust it, and he does not know anything about the dozens od dozens secure bowline-like loops, which are more easy to tie and untie ( and untie in only one step ) than
any eyeknot based on an interlocked-overhand-knot ( or, for that matter, an interlocked-fig.8 knot bend ).
This fake Zeppelin knot will NEVER become "
accepted as a tie-in knot", albeit for the wrong reason !
Its difficulty to be tied will
save the true Zeppelin knot, the Zeppelin bend, from this
faux bijoux. So, people who had never understood how the real Zeppelin knot and/or the bowline works, will also not understand why this knot recipe will not be mentioned in many places - even after
centuries !
A necessary ingredient for a popular
myth is to be naive and simplistic enough, in order to be able to be rehearsed / reproduced by the believers easily - and, unfortunately for them, this knot is not so easy to tie ...
