All knots in my videos “failed”. But the knot knot4u was talking about is the bell ringer + half hitch lock. Even though it slipped and jammed knot4u is saying that there is no need to go all out and make a ABOK #173 + half hitch lock which will eventually ALSO slip and jam.
He is saying that you can get the same result (slip and jam) with both knots so why go the extra step required for an ABOK #173 + half hitch lock knot. That is how I understood knot4u’s post.
EDIT: I am also now lost. Disregard my paraphrasing of knot4u.
I use a span loop almost exclusively for my truckers hitches and versatackle systems for the sole reason that it is so easy to untie.
