Yes, Ashley's Stopper (eschew the "oysterman's" myth)

Did you like my "lineage" joke? I'll stop using "oysterman's" (
can't even spell it, besides, where's the umlaut on this keyboard?), but I may need help cutting back on the nomenclature jokes. I'm just knot-headed enough to throw a kink in a cord & if anyone insists on my giving it a name, I'll make one up on the spot! Don't care what you call it, I just want to secure "this" to "that" using this piece of rope. I prefer to point out the "features" of the knot & why that feature is needed at that point -- DanL's "nipping bight" is an example. This is how I see knots anyway; "
this part keeps
that part from moving,
this other part is how you untie it" -- that sort of thing.
Or (back on topic) I just want to keep this piece of rope from leaving me, if I have to let it go.
Still on topic, you can tell my answer to the original poster would be "call it what you want to call it, unless someone can give you a name you like better. My "case in point" is what motiviated me to sign up here: "My" "Single Bottle Knot" nee "Jimbo's Jug Sling". I can't even remember how long I've been throwing that knot, and never
ever thought of a name until a neice asked. "Uh... Well... What do
you want to call it, dear Neice?" I just dropped the "Uncle" for public consumption. Durned but my brother & sister have some smart kids!!!
As someone wearing a mustache just like mine once said, "it ain't about ABOoK, it's about a clever kink in a cord."
To Roy: I probably forgot to tell you that what got me "into" knotting (at maybe age 3 or 4, IIRC) was UNtying a knot, so your desire to remove said stopper is near & dear to my heart!! Just not in one of my "Pet Rope Harnesses". So yes, I completely agree, but show me how to untie a Manrope/Tack knot after following Hervey Garrett-Smith's instructions. That's the "look" I'm after, but in smallish (pet harness sized - say something no bigger than your index finger) Kernmantle (not plait, as I need a "pretty" eye on the other end and I'd rather look at potato eyes than plait eyes!!!).
Anyway, as to the topic (which I apologize for somewhat hijacking even though this started in my "Ashley's" thread), the "Double-Crossed Figure Eight" (made that up just this moment) Stopper looks like something I'll use, perhaps instead of my customary double OH stoppers (which want a hatchet to untie).
