Ianxm, thanks for this!

It's a fun end-2-end joint to play with, and could see some
value for its forcible loosening, perhaps. The thing is, though,
that there are some good end-2-end joints such as
Ashley's
#1408 which are non-jamming and, so, easily untied.
How'd you come up with this, btw? (I discovered an end-2-end
joint of interlocked
overhand knots that generally can be
forcibly loosened much like this. But it's not something I find
myself using (and might need to consult my drawings in order
to tie it).)
