It is a very good knot, as good as, IMHO (if not better), than the Zeppelin.
Just to be clear : I am alert to attacking what strike me
as "fan boy" raves about the
z. and to advance what
IMO are often --per situation-- better knots, such as either
Ashley's (#1452) & (1425 (not "1425a")).
But, I will also remark that my keys ring is tied onto small
binding cord (a hollow braid of
nylon=>"polyester flat braid", which semi-flattens) [2023-07-23 edit]
closed by the
z. with ends so short that their fibres are
*mushroomed*/spread against the knot body, and this
has been in place for a
decade or longer** (I have no reason
to untie it) !! --while pretty much all knots, including
a
z. tied in some of the small, 3/16"(4mm?) solid
braid nylon play cords tied to this key cord (along with
a small (10') tape measure have inevitably loosened.
The holding
zeppelin is by no means "tight/jammed",
but those mushroomed tails
done=>don't come out, and the [2023-07-23 edit]
knot must not take much of abrasion/rubbing the
way the slightly flattened small cord sits.
(**could be two decades!)
