Regular watcher of TRAC, think I came across your via there, more interested in Rope Access these days but do bits of climbing years ago, knotwork; one of those skills that never leaves you and surprises you how often you use it outside of your main reason for using it (climbing, rope access etc). I think I came across RopeLab from here though, can't recall exactly. Keep up the great work.

I stumbled upon a knot where you make a simple loop and make yet another loop 90° offset and 180° flipped inside that loop. This would result in 2 interconnected loops with 1 pass outside and 2 inside. Another variation is 2 double loops interconnected in the same way 2 passes outside, 3 inside. I'm curious if this already exists, how strong it is and how it's called

@HowNOT2 What if we take the end loop and wrap it around and through the "hole" loop one more time? It will be same knot but with *four* ropes hugged in the center loop instead of two. This theoretically might increase its strength because of a bigger bend radius as well as reduce the chance of it coming undone (not in Dyneema).

I was actually taught that the butterfly can be used to reduce shock loads on static ropes due to its tendency to slip on high loads. I would be so curious to see how it performs in that role!

I don't understand the need for either of the 2 complicated methods they showed. You can do the standard method of wrapping 3 times around your hand, but do it with both strands, and you'll end up with the same double-loop butterfly knot.

The fastest way to tie it is wrapping around your hand though. Your fingers are just as likely to get munted if you have something tighten while you are doing the twist method especially when threading through. Maybe you have a different one but I know that most of our Fire and Emergency (FENZ) use the twist method but firemen usually know F.A about ropes as they are not climbers first and foremost.

I've actually been using the "Wrong" alpine butterfly(like at 19:30) on purpose when I set up Lead Rope Solo anchors. Has a SS quick link in the loop, so it will never pull through. The "wrong version" is quicker to adjust for equalizing the anchor, and is even easier to untie if I take a whipper on it. If anything, the little slip is a little softer catch.

Ooo Prusik Peak! Love the Core!

Maybe it’s just cuz I’m from Washington but it’s instantly recognizable. There’s like Half Dome, the Hulk, and then Prusik in the Core. Stanley-Burgner 👌🏻

Really grateful to see the results of the last variation you tied 'incorrectly' so to speak. In the UK, I know that as a cavers knot. I often use both to link anchors together, using the alpine if they are relatively close or the cavers if there is more distance between. I would tie the cavers as a slip knot locked off with a half hitch over the eye. 🤷‍♂️ Love you vids, thanks for knowledge share. Happy New Year.

As a long-time UK/alpine caver (my 40th anniversary of playing around on ropes is coming up in December) , virtually every caver I know who rigs ties the true Alpine. I have only personally experienced one person choosing to tie the non-interlocked-wings #3 as a regular rigging knot, and he was a somewhat newbie rigger I once took on a practice rigging trip. Once, and never again. He rigged using #3 tied in two stages (a single overhand with a loop, and another single overhand to finish), which he claimed *was* an Alpine, was faster to tie, and was easier to fine-tune knot-anchor lengths with than other ways of tying it, and which he'd been taught by some supposed instructor(*) he seemed to have some kind of hero worship thing going on with. Politely demonstrating to him that he was wrong on all three of his claims didn't seem to affect his misplaced hero worship in the least. To be fair, his knot might have not been meaningfully worse in terms of absolute strength, but it just *looked* really wrong under the not uncommon meaningful 3-way loading, and hanging your entire weight off knots that look wrong isn't many people's idea of fun. (*Note: this isn't instructor-bashing - some of my friends are great caving instructors, but whoever *that* guy was, I have to wonder what his history was.)

​@@davewilson4493 That's an interesting statement Dave, that you haven't seen it in all those years. I was shown it by several CIC's and a British Mountain Guide when I was in the industry full time. Shame you only saw fit to take the person once for rigging practice, rather than choosing to put in some development time. Though I understand there could be other factors involved, some people you just have feelings about and those aren't the ones you want to rely on when people lives are at stake. As for your opinion of his three claims, you're right it is not an Alpine Butterfly. However, I would argue that it is super adjustable especially if the anchor is a metre plus away from the equalisation point. That said, rigging a traverse line why wouldn't you use and Alpine. I was just pleased to know that the 'Cavers Knot' as I know it was Super Good Enough 😊

You're knot gonna believe it, but that is Prusik Peak!

I have had the butterfly loop spontaneously show up in different ways in my life. Several times when reeling in old line to my fishing rod the memory of the line formed a coil that twisted and trapped a bight. Another time my kid was playing with some cord and asked if a loop was a knot. Mind you that they aren't able to tie their shoes, so this was a luck discovery. With this in mind, I am sure this knot has been around and used long before it was recorded in print.

Great video. Looks like watersprite lake in the background

Great analysis of this iconic knot. I don't see that anyone answered you opening question ..... what's on the green screen behind you? You are in the Enchantments Permit area, likely at Gnome Tarn. Over your left shoulder is Prusik Peak, to the right, the knob is the High Priest, the jagged ridge is The Temple group. We packed into the plateau twice in the early 70',s, long before permits were required. Wish that I still had the knees to get up there again!

always very educating and brought in a very accessible way , any chance you might want to show how knots infuence the strenght of "standard rigging slings "

Prusik Peak! I love living so close to that range.

This is a great video but, for the love of God, why not show a pull test on the double butterfly? That is one of the most used knots for retrievable anchors and load share systems in Rope access. These are considered two independent knots in one and used in a two rope system. It is widely used throughout the industry, yet I have never seen conclusive testing on it. Help us HowNOT2! You're our only hope!!

Gnome Tarn. I have that same shot from climbing Prusik Peak, beautiful.

I think the main benefit to some knots is being easy to check. As i see it, the only reason we use the figure 8 for tying in is that you can dress it nice and it's easy even for beginners to check (and easy to untie if i can remember which side for the loaded strand). Tons of other knots are super good enough. Personally, I found it really hard to tell the difference between the butterfly mistakes. But seeing how the "wrong" butterflies are still strong makes me less scared (though I'll definitely do an overhand backup on a core shot now) I need to look through and see if you've tested the wrong ways of tying a bowline as that's the one knot i've actually argued with someone about which was the "right" knot.

Thanks for this extremely nice video! Do you have any idea what made the knot slip in some of the tests and not in others? Is there anything one can do to prevent slipping, other than putting something in the bight?

I like knots that are: a) easy to tie b) easy to inspect I never use the butterfly because it is neither. Here is a wee test to show if the butterfly is easy to inspect. Take a piece of paper and from memory draw a figure eight knot. Now from memory draw a butterfly knot. A rule of thumb could therefore be - if you can't easily draw it you can't easily inspect it.

I have no idea why I'm fascinated with just a handfull of knots.. I feel like I have the secret to the universe when I make a bowline or hitch..

I did the knot exactly as you describe at 3:42 in the video and compared it with the right/wrong version at 19:48 and it doesn't look like any of them! On checking, the image you have at 19:48 is a mirror image of reality - only when the image is mirrored back again does the knot look like the one with the tick. I'm surprised nobody has noticed this.

I see we agree on the name. now I know you are GOOD!

Amazeballs video. I use the butterfly all the time. Almost as much as the 8 and clove. Great to see its strengths and weaknesses. Also learned a new way to tie it. Ps. Your puffie is loud. 😅

I was taught the twist method and have never tied this by wrapping around my hand; though I’ve always been decent with knots and haven’t really had difficulty learning new knots.

Yee ol' prusik peak. Enchantments are gorgeous.

I give it a like because, for the first time I see the Ashley knot number on KZread.

Good info. One thing you haven't tested... The butterfly knot is not mirrored in itself. So pulling the loop to the left is different from pulling the loop to the right. The other standing part of the rope is tensioned. Care to try that sometime?

huh interesting! I just used a phallic knot as my stopper with an overhand for a tagline rappel on a reepschnur hitch. I will now only be tying the double phallic.

This knot makes a great bend or tied differently, an end loop.

Nice! And super nice video. Another use for the alpine butterfly: Isolated retrievable system. Isolate 1 strand for rapell for a retrievable system, on a grigri, be pilot or whatever. At the anchor with the rope through, tie a alpine butterfly on one side of the anchor, either clip a carabiner to that AND the other side of the anchor. (,Can also be done without the carabiner, thread the other side rope through) Now you can rapell of one strand safley, and pull the other from below to retrieve the system. Used in arborism, can even be set up from below, throwing the rope over a branch with a weight. But don't take my word for it. Strider tree gear kzread.info/dash/bejne/an1orqyFYsexk8o.html That also shows.the alpine butterfly is a trusted stoppern knot... This could be tested! :D

In climbing one of the uses for the alpine is to use it as a bend, to actually to separate a damaged section of rope, especially for rappelling, at which point you'd have to pass the knot. So it slipping is important- granted at +10kn, not a force likely to generate while rappelling

Awesome video. Love the idea ABK suggests this knot is only 100 plus years old. Backdrop: Sundial Peak (Big Cottonwood Canyon, Utah)?

I know this knot as a mobius butterfly. In this form it becomes more suited to an endline knot than midline, or to create two independently loadable strands. And unlike many other loop knots it can take pretty much any loading profile if you dress it well (in-line, perpendicular, circumferential).

Nice work. At about 20 min in would you call that an overhand loop with an half-hitch backup?

i had had a wrongly tied butterfly that had load on it, it didn't give, but it was pretty hard to undo afterwards

"Or when you're done wiping" 😂

Personally the way I find is easiest for students to learn is wrap one into crook of thumb, wrap two around base of fingers,third wrap between the two.pull the outside one out as long as required,take the bight and feed it under all the strands from wrist out towards the fingers.

I find it hard to describe in words how I tie knots. For rigging in caves, for most knots, I like to measure the loop length I want, add on appropriate extra for the knot, and then use my left hand to build the knot up from the known desired base point. It keeps things where I want them to be, and works well from muscle memory even when I'm not really in a position to look at what I'm doing For the Alpine, though I know people who do the hand wrap. I don't like it as it's hard to get the very short loops I often want, and not intuitive to me for meaningfully long loops (and sometimes I need *really* long loops). I go for the two-twist method which works for tiny and super-long loops exactly the same way. I hold twist the base of the knot where I want it and hold it between the base of my thumb and the bottom of my little finger with my thumb over it to hold the first twist firmly, twist again and hold that twist with my index finger, and then pull the loop behind and under my hand and push it through where my thumb is, sliding out my thumb at the same time but keeping hold of the base of the knot while I tighten so the base stays where I want it to be. If the desired loop is somewhat long, I may need to jiggle my left index finger, and/or spread my right hand holding the loop top to widen the top of the loop and move the second crossover point further down the knot to where the crossover is easier for my index finger to catch it.
