It is the
first time I see this loop - and I like it !
( I would also like to learn about the history of this knot, by anyone who might know some things... )
It is a crossing-knot based loop - such loops can be very stable and secure, but they have remained unknown to knot tyers, I had never understood why...
Also, this slipped tail, which makes it easy to untie, almost like an "exploding" knot, is a very good idea - because, as a doubled line, it adds stiffness to the "toggle" which prevents the opening and destruction of the crossing knot itself.
I had tied two "similar" loops, the
Pet loop, which is a crossing-knot based fixed loop, and the
Pretzel loop, which is an adjustable loop, without a collar - and I see that both have elements reminding the
Kalmyk loop.
Will it will ever "replace" the bowline ? I do not think so, because it is a more complex loop, and it has this not-loaded, functionally redundant and possibly problematic bight of the slipped tail. However, it is TIB, and this is a great advantage - so we should better compare it with simple TIB bowlines - of which we have maaany !
P.S. I had missed this thread, or I have forgotten it, I do not remember why...
