In relation to your post at 'reply 45'
Thanks Alan, nicely presented and an interesting variation.
(also 'TIB').
An old saying... "Its hard to build a better mousetrap"!
The original #1053 Butterfly is very simple and relatively easy to tie (and can be tied one handed).
To improve on it is no easy task!
I had played with your posted variation some years back - but thought it 'unwieldly' but nevertheless
interesting.
While trying to re-tie your presentation from memory (without looking at your images as a reference) - I ended up with the variation shown in my attached images.
I have no idea if you or anyone else had previously tied my presented variation?
I am not finding the search function user friendly... searches for Butterfly variations isn't producing helpful results.
Anyhow, I am using the working title "XT Butterfly" (Xtra Turn Butterfly).
Its 'TIB' (Tiable In the Bight) - meaning the knot can be tied without access to any end.
I note Mr Lehman using 'NSUE' (a French term), instead of "TIB", citing issues with the word 'Bight'.
I'll tender my new term... '
MRT' (Mid Rope Tiable) to add to the vernacular.
I'm not claiming that I invented the term 'Mid Rope Tiable' - its been thrown about before (but, it does seem logical).
EDITAnother acronym for you is "TWATE" (Tiable Without Access To an End).
There you have it... 'MRT' or 'TWATE'
[I can see how the term 'TWATE' can be humorously modified!]
Anyhow, I did not post my presented variation in
New Knot Investigations - because I believe Alan or Xarax had likely tied it before...
