Here are two perspectives on the same knot token, which I guess I
must have loaded to roughly 300 # or so. ...
There are various ways to dress 1425; here, the collars were left large
enough that they draw snug to the body. This seems to lessen the
deflection of the S.Part at the point of contact w/the collar, and I'm
guessing helps strength & chafe. ...
The ropes are, resp. of black & yellow roughly 1/2" dia., a hard-laid
PP (polypropylene) and a firm old double-braid of either nylon or polyester.
(You wouldn't want to have to splice the black rope, though this piece
was found with a 2-tuck eye-splice in it (splicer probably said "eNUFF!"
at that point!).)
Which goes to the point of suggesting that were these ropes replaced
by some with pretty compressible cross sections, the knot geometry
would be different. ...

Repeated for easy comparison in this post is the large-collars #1452
and newly added here is a small-collars #1452. As noted above,
the former was done expressly to achieve the collars-around-body
state, which state however can be jammed (YMMV) --not to confuse
though, this is NOT "the jamming form" referred to elsewhere : that
version orients the tails differently (on opposite sides of each other).
With smaller collars, they are not able to open and wrap around and
jam onto the rest of the knot. Conceivably, as with a bowline or
sheet bend, these collars in an elastic material can tighten around
a diameter-diminished (by tension) S.Part and give a sort of lock
on relaxation, preserving tension in the knot.
