Tying the Triple Fisherman's Knot
Вставка
- Опубліковано 16 жов 2024
- The Triple Fisherman's knot (which is technically a bend and therefore is commonly referred to as the Triple Fisherman's Bend) is used to join two ropes or the ends of a single rope or cord, commonly used to make Prusik Loops for friction hitches. It is strong and secure, but difficult to untie after loading.

I went looking for a video for my boys to watch when practicing their bends and came across yours.
The fisherman's tie is *EASY* to untie even after loading. It's one of the features of the bend that no matter how loaded you get it, the knot will not jam if tied properly. Manually split the wraps of the overhand with your fingers and draw the working end out. It's next to impossible for it to come untied without intentionally untying it, but once you want to: it's dead simple. There are certainly bends that are much faster to untie, but the Fisherman's Tie (double or triple)is Ole Faithful.
I have a prusik loop closed with a triple fisherman's bend that i tied a long time ago and climbed on for a couple years ... and after all that loading and some wet weather, etc, it's not possible to untie without getting some tools and likely damaging the cord. I feel that the sliding triple fisherman's is fine to untie but if we need a loop, I prefer the Hunters Bend. If you're going to try to untie it, be sure it has seen your full body weight and a few bounces to get it set. And of course, the smaller the cord diameter, the more difficult to untie.
@@jrbtc I'm trying to picture your description. Are you saying that you captured a Prusik *between* the overhand knots of the Fisherman's Tie?
@@kalan4787 no. I am saying that if we take a length of cord and close it with a triple fisherman's knot (the Bend in this video), we are holding a loop, AKA a prusik loop in our hand. With that, we can form a Prusik or Klemheist or Bachmann or Hedden friction hitch by affixing it on a larger diameter rope. And if we climb on that, we are subjecting it to our body weight and that will load the bend nicely. And it will make it more difficult to untie.
@@jrbtc Ah! You're saying that you CAPSIZED your Fisherman Bend into a Prusik Loop. Of course it didn't behave like a Fisherman's Bend; it behaved like a Prusik.
They are not the same thing at all.
@@kalan4787 i am sorry we are having difficulty communicating what I was saying. There was nothing capsized. I read my earlier comments and believe they are accurate. I am saying that certain friction hitches (for rope climbing applications) are formed with a closed loop of cordage. A Prusik is one example. A closed loop of cordage cannot be manufactured: its either sewn into a loop or tied into a loop using a bend. In this, case i tied it using a triple fisherman's knot and after doing so and using it, it's very difficult to untie. If you want to disagree that's fine, but before doing so, please attempt it: get some 6mm cord, tie a loop, then set it with your full body weight a few times. It's difficult to untie, much more difficult than a Hunter's Bend
Excellent video! Super easy to follow and informative. 👍
My pleasure. It was on my list and knowing that someone needed the info is just the right kind of motivation. Be safe.
Is there an advantage to add loops to use more slippery rope?
I didn't invent this and have not done formal testing of it. But in theory, more wraps cannot make it weaker, but can make it stronger. My guess is that a triple is stronger than a double, but at some point, we reach its maximum strength and more wraps are not helping. I believe triple is all we need.
I love seeing HowNot2 videos on how they fail, and it's crazy how much the tails tend suck right in (regarding ~1:12 and why to leave substantial tail)
@meganw6007 absolutely agree. So many vendors in hunting are selling products with inadequate tails on knots of all varieties.
01:12 - How about potentially leaving something like figure eights on those tails to add security, would this be reasonable?
All my research says that the triple fisherman's knot is as secure a bend as we will tie and is intrinsically secure, meaning that no stopper or backup is required. I am aware of no forces we are capable of generating as climbers in properly rigged systems that would come close to testing this bend.
@@jrbtc right, cheers for that.
Could you perchance elaborate on that pattern of failure that you referred to there (and which undoubtedly, then, would be the result of a force regime exceeding the bounds of any proper rigging activity like you point out in the comment ... all the same, just out of curiosity: asking in light of your having outlined the best practice rationale for tail inches in the video)
@@treedom5094 i have not personally pulled a triple fisherman's to failure but I have done so to it's cousin, the scaffold knot. As you reach extreme loading, the tails get pulled in just a bit. I believe the recommended minimum tail length is 10x the diameter of the rope. However, I prefer to leave them even longer. You just never know when you might want something to be a little bit longer, and with a little extra in the tails, you don't need cut on new piece of cord.
@@jrbtc That is great to know, thanks for the insight. Perhaps I might run the triple testing at some point ... one day.
Are you introducing this as an alternative to the Hunter's Bend for a closing knot on hitches?
This video is not specifically related to the JRB Climbing Method, but can be used in it, as can other secure bends. In practice, the double and triple fisherman's knot is the standard bend for construction of prusik loops, and my use of Hunters/Riggers bend is an alternative, for applications where the loops may need to be periodically on tied and retied, either to adjust their length or redistributed wear on the adjacent friction hitch. In that regard, Hunters is better. However, for a permanent loop of fixed length, triple fisherman's is the standard. It's also regarded as one of strongest bends. Stay tuned for other secure knots and bends.
I wonder what inspired this video... ;)
Hey buddy, yes it was for Adam, who already commented. I have many that I know and use and am planning videos on, but he asked a question and that motivated me to share what I know on this one. Cheers and be safe.
Not the triple fish at all I climb on the triple fish this knot is just a fishermen's bend period
Respectfully, what you call a knot and what someone told you was the name of a knot is not necessarily the correct name of a knot. And in this case, the actual names are terrible. What you think is a triple fisherman's knot is actually a scaffold knot, ABOK #1120. Ashley's Book of knots was published in 1944. Its been the knot Bible ever since. This is indeed a "triple fisherman's knot", which is actually a bend, and with 2 turns would be a double fisherman's knot and with one would simply be a fisherman's knot. Abok $1840 depicts the Fisherman's Bend ... and its not a bend at all, its hitch.

Damn, Mike Porter just got served. Now you gotta have a dance battle
@@Maxedoutminimalist in his defense, half the arborist community calls a Poachers or a Scaffold knot a 'fisherman's knot' but there's no legitimate reference for that. And i can't dance...
