Like that, it is actually more of a proper stopper knot.
Must admit would not be on my list for that purpose, and you have to be careful with it apprently. Fails 65% of the time according to wiki.
That is why I said it has almost replaced it, if doing a demo, or planning on undoing it will use a clove hitch.
You have to watch Cloves, when not under tension from both directions they come undone.
That's why it is called a ''stopper knot''
The essence of a good knot is that while it should obviously hold firm in use it should also be very easy to untie after use, tied correctly the carrick bend is an excellent perfectly symmetrical knot that will not jam even after very heavy load or even when soaked, especially good in thicker ropes,
The fact a knot is hard to untie after use is a bad choice of knot if it does need to be untied, a good knot is as easy to untie as it is to tie, that is differnent to a bad knot working loose.
Clove hitch if used correclty will not come undone when under tension from one end only if you load the '''Correct End''', it would not be a reccommeneded knot for climbing, as it is, if it was unreliable, it is important ''which'' end to exert load onto, if you examine a clove hitch you will see one end tightens knot and the other end loosens knot, you load the end that tightens knot it will not come undone.
That description sounds a bit like the
Fisherman's knot described here, but not quite. There is also a
double fisherman's knot.
There seems to be a bit of name confusion with the
Anchor bend which is also sometimes called the fisherman's knot/bend, but looks more like a round turn and two half hitches.
The zeppelin bend mentioned in my earlier post is a superb knot for untying, even after heavy load. It's the knot I use to to join the string to tension my collapsible bowsaw.
The fishermans/double fisherman's (one loop or two over standing part) is a very good reliable klnot, it can sometimes be hard to untie after heavy load, if you tie a reef knot first then follow up with a double-fisherman's with the loose ends it is easier to untie after use and still very relaible, there is a proper technique for untying a double-fisherman's where you sort of roll the ends over to loosen the knot.
The Anchor Bend is a round turn with two half-hitches but the first half-hitch must go through/inside the round turn first.
The Zeppelin Bend is an excellent knot for joining, the essence of all good knots is that they are easy to untie after use, as is the zeppelin bend.
