I also noticed that if rope end is worned out it makes it harder to untie as well... But would need more experiments to prove that ;) Aaaand let's see how many comments I get that bowline is better :D yea... it's easier to untie, but not the point of my video ;)
@@AW-po7jr no, not going to... Because it doesn't result into actionable conclusion ;) It's obvious that you shouldn't climb on worned out out ends anyway... I have better content coming
Easily one of the most useful climbing/gear videos I've ever seen! I'd been taught how to correctly tie the knot, but not to tighten it one strand at a time. Amazing.
After 17 years of climbing this is surprising, but most appreciated information. It makes perfectly sense, and thank you for showing it. Hardest part when watching this however was, that we had to wait almost to the end before the curtain was lifted and the secret was unveiled. So glad I learned this now.
Thank you! Most edifying! I have never paid attention to whether the load line is on the top or bottom and, consequently, have always been baffled by why *some* of my figure-8s are easy to untie after a load and others are an incredible pain.
This explains so much about my experience with fig-8s! I had so much trouble with hard-to-untie knots that I switched to a bowline. It also explains why other people I know had no problem untying their knots. Now I will experiment again with well-tied fig-8s 😊
Tip: If you do use a Yosemite backup and it's stuck after some hard falls, clip in a biner to the backup loop as shown BUT don't pull, twist it like you're wringing out a wet towel. Keep twisting and you'll get way more leverage to pull out the tail, then you can untie the rest as normal. Or, y'know, just ditch the backup and do what he says in the video :)
I have started to pay more attention to how I've been tying the figure 8 and by keeping the load loop inside the end loop it certainly makes a huge difference. Thank you so much.
Brilliant video! The most common is the people who do an overlap when tie the not... Usually it is for lack of info... Good job and great effort you did... Videos like this is what the community needs! 😄😄
You just proved me right in a friendly argument I had last year about better ways of tieing a figure 8. I noticed the positioning of the load on top and middle differences a few years back. Great video.
Loved the video. I think being a beginner, I fell into the trap of thinking "if I tie loosely, the knot will remain loosely and will be easier to untie" which apparently was blatantly wrong. :o Thank you for the testing, this was really interesting!
@@HardIsEasy I feel like when I see the video, it's seems so obvious that the results are as shown (tight being easier to untie and the comparison at the end as well) but I still didn't really make the connection myself beforehand. So thank you for the light bulb moment :)
In my experience there is a sweet spot in the middle. If you pull the knot really really tight it gets harder to untie (especially if you didn’t take a fall).
When you discover things you didn't know you didn't know. Thought I knew how to tie a figure of 8. I think the difficulty comes in tying it in the follow through method as there's lots of ways to follow it wrong to setup for the fusing scenario. Interesting that I must be kind of inconsistent because sometimes I do it write and I have no problem, then sometimes I do it wrong and really have to struggle. Thanks for bring out the nuances of tying a figure of 8. Very interesting.
@@HardIsEasy definitely will pay attention to this. The next 25 years will answer this. Thank you for pointing this out. Found you today and I'm devouring your videos, and clicking the ads once in a while; You deserve it!
Thanks for that Video. I didn't realise, i usually tie up my Fig.8 with the loaded strand in the middle... That's why i never had any issues, untying my knot. Thanks for your work.
Even though I don’t use the figure 8 anymore, I still like how much effort you put into this video. I subbed and I am looking forward to watch all of your quality content
Thanks for these experiments! I switched to bowlines a long time ago, because I always had trouble opening the figure 8 after a fall - especially with the sticky ropes in our gym. I'll try it next time.
I just joined the channel because you really put effort on it ,and you finish with conclusions which make this sport better. Thanks for those great videos
Thank you for all that effort! Brilliantly presented. After more than 50 years of tying the load rope on the top because I was told it had a greater radius I’ve now to relearn to tie it correctly!!
This is brilliant, thanks! I never realised the difference between load line routing and how it could make a difference. Would be good to see if there's actually any difference in the breaking load of both, not that it would make any real world difference, clearly the load line in the middle is better for untying.
Im just starting with climbing and I feel yout videos save me years of experience to learn some deep concepts, amazing content, keep uploading strict and scientific videos :D
Although I am not a rock climber, I found this episode very interesting. Expanding my knowledge is a passion of mine. This information will be shared with my wife's grandson who is a firefighter. Hopefully his training has them using the correct way of tying the figure 8 knot. Thank you for sharing.
I'm unfamiliar but unsure if big falls on the knot are a large enough concern in that line of work, and remember if it ties too hard you can always cut the rope. Otherwise both ways are correct safety wise. It still doesn't hurt to tie in this way. I think always tying the same way might be a good idea, if you are having an especially bad day it might help to spot something's not right.
As a climbing gym that uses indirect tying-in (with a safebiner), we actually use the harder-to-untie-version at 16:14 :), this is to prevent two things: 1. climbers untieing the knots and putting bad ones back in 2. the visually good looking one gets an extra loop after a while (because the top of the knot is not being loaded, it's being loaded half-way the top becomes looser), which climbers could unintentionally tie into, which would be disastrous. Super interesting video!
@@HardIsEasy Yes this is only for toproping. The figure eight is already made. The climber ties himself into the loop with a safebiner such as a belaymaster or Smart HMS (other biners are not allowed due to possible cross-loading)
@@devonrd in my gym for the top roping we have two semi-auto locking carabiners always fixed into figure 8 or bowline loop so nobody gets to untie the knot or unclip the carabiners off the rope which is fairly safe
Brilliant! (You may not be the first person to figure this out, but I'll give you credit because I've never seen it anywhere else.) Thanks for adding to the collective knowledge!
Thank you so much for all the work you do for the community. I come from a tree climber background but still find all of your content extremely relevant.
It's been interesting to see the practice change around this. In my Mountaineer's handbook from the early 90s, it shows the rope going around the outside, including around the top of the loop and at the end. Now we pull it through the inner loop - much easier to untie!
The crossed inner strands on a figure 8... That drives my OCD crazy to even see. But i was never worried about tightening them down tight. Now I think I will.
So, I am at 9:18 viewing this... but I cannot help but wonder if you also controlled whether a difference in untying times could also have something to do with which knot was closest to the floor vs ceiling. I know that intuitively it would seem not to be necessary to check that... but I don't think what is intuitive is necessarily true. (Sorry for bring this up... because checking that would be a lot more work. Great and very useful video. Thank you. I find all of your videos to be very well done, and very detailed. Also... if you always drop it from the same height, and do not throw it down, I would think that would be a more consistent set of forces and therefore reduce a margin of error that may be due to one more variable. That said, real life falls all will have variations in the resulting forces, right?
"Start hard, finish easy" is all you gotta do. Leads to the least time taken to dress the knot. That it happens to untie easier is just icing on the cake.
I agree you put out great videos, and I'm learning a ton. But what I really love about your videos is your sense of humor. Every video I'm laughing my ass off at something. Great content man! 👌
Ive only been climbing for 7 months. Ive never had an issue untying my double figure 8's. But ill thank the gym staff for correctly teaching me how to tie the double figure 8
Awesome video! I always have problems undoing my Figure 8, especially after a couple hard falls. Tried reversing my follow through as well as snugging up the 4 rope ends out of the knot during the last few climbing sessions since watching this video. It was so easy to untie!
Thank you Hard Is Easy!! Love your videos. This Climbing Human will definitely make sure to have dress my knot, have load line thru the middle of knot, and not have any crossed strands.
In the Toyota Lean production system the main goal is to keep the ropes tight. Stay organized, stay clean...to see the problem, the missing things, or any defect. But here is the real meaning of this sentence. Keep the rope tight to save your life and make easier your life to untie a knot after a fall. Just a tiny differences, but at the end the difference is reeeeealy huge. Thanks man!
Would like to add that few people know or bother to tie a "dressed up" figure of 8. This should also reduce time of untying. You do so, but it will be beneficial to the community to show how to do it. Thank you for the videos.
Something to note: you untie knots correctly. You push the loops of the knot apart. Most people I teach (I'm an instructor) try to pull the tag end or load strand out of the knot, rather than pushing the loops up, over the the two strands of rope where they exit the knot. Great video! I hope people watching notice that you push the knot apart, rather than trying to pull strands out. It makes a huge difference in untying.
Yosemite is actually easy to screw up if you tighten in the wrong order. Best thing about f8 is that it's essentially foolproof AND incredibly easy to inspect.
Have a look at scotts locked bowline. Super simple, fast, and one of the most secure bowline variants. It's kinda absurd that it wasn't discovered and used decades ago
@@johnliungman1333 Scotts is just super simple, and also very secure. www.paci.com.au/knots.php has a 77 page write up on loads of variations of bowlines, the very last page has the secure variants
I will still stick with my bowline with double stop knot, but this is really interesting, I never thought that there was 2 ways to tie a figure of 8 knot. Thanks for the video !
Yes, me too. Since I don't do competitions (where a figure 8 is required) I learned it. It convinced me that they use this knot to secure huge ships and are still able to easily open it :) Works like a charm - even with the sticky ropes in climbing gyms.
Absolutely great made and entertaining. I was not sure if I could learn something when I started the video and than boom - excellent and thank you for sharing :)
And here I was blaming the knot for being difficult to untie, when it was mostly my fault. But I think I'll still use double bowline, just because I think there is less room for stupid errors when doing it correctly. But I'll definetely try to check which variation of figure 8 I do when tying in. Probably both. Anyways, I think Your channel is evolving in the right direction, from being just another climbing vlog to seriously interesting and useful content. Keep it up! ;)
Thanks Buddy! Amazing coment! Bowline is great, but lots of bowline users neglect the fact that a lot of people don't know how to double check it ;) So if your partner does - amazing... keep in mind that there are 5 bowline variations and some random partner might just nod - yea yea good climb, but actually don't admit that he's confused looking at your knot ;)
Hello Ben - thanks for your time and effort in producing this video, it is appreciated. I would like to provide some critical feedback - which I am providing in good faith. The first point I would like to make is that there are in fact four (4) possible geometric orientations of the #1047 Figure 8 eye knot. I'll refer to it as an 'F8' from this point to keep it short and simple. You stated there are 2 different orientations - when in fact there are 4. I note that you have a natural tendency to tie your F8 knots in 'S' chirality. Hold your F8 knot adjacent to plane mirror and you will see a reflected image showing opposite ('Z') chirality. Chirality is found everywhere in nature - for example, humans all have a left hand and a right hand. You cant flip, turn or rotate your left hand to convert it into a right hand...its always a left hand. However, you can hold your left hand adjacent to a plane mirror, and the reflected image you see will appear as a right hand! You can perform this exercise with any hand tied knot. Tie a knot in your natural (preferred) way and then hold it adjacent to a plane mirror. You will see a reflected image with opposite chirality. Note that the reflected image is equally valid. I am of the view that you are unaware of the chiral nature of knots - and that the geometric orientation of your knots are influenced by your dominant hand (and also influenced by how you first learned how to tie an F8 knot from your instructor - or if self-taught from a book). Given that all of your F8 knots have 'S' chirality - it leads me to think that you are left-handed? That is, left-hand dominant people tend to tie their F8 and 'Bowline' knots with 'S' chirality. Right hand dominant people tend to tie these knots with 'Z' chirality. The second point is that you should not mix two different knot geometries in one test. There is a rule in testing which basically states that you should only test for one variable at a time - and you also need a 'control' (ie the 'scientific method'). Now - I am fully aware that you are not an accredited test lab and therefore are not obligated to follow the 'scientific method'. However, I urge you to only test one variable at a time - don't mix two different knot geometries in a single test. Example: In in test, tie two (2) identical F8 knots - in other words, both knots have exactly the same geometric orientation. Don't have one geometric orientation at one end and a different geometric orientation at the other end. Perform your dynamic drop tests as you have been doing (although standing on a table isn't exactly a 'safe' technique!). Note that you ideally should attach a load cell to measure the peak load reached - otherwise we have no idea of what force you are achieving (without a load cell - its not possible to know with precision what peak load you are reaching). This makes it harder for others to try to repeat your test results... If you tie two identical F8 knots - you will be able to compare one against the other - which will provide you with opportunities for further insight. Note that you may find one knot harder/easier to untie than the other. This is due to the fact that you have a stationary anchor at one end, and a moving load at the opposite end (there will be a short time delay in transmission of force along the line...it won't be instantaneous - force doesn't propagate at the speed of light). You should take careful note of which knot is easier to untie relative to the other - and report this. Perform the same test (ie repeat) with an F8 knot tied with different geometric orientation (ie both ends of the rope tied with identical F8 knots). After the test, take note (again) of any differences between the two F8 knots. For example, do you note any difference between the two F8 knots? The last point is that you are performing dynamic drop tests - where the knot specimen is subjected to a sudden (very rapid) increase in load. An alternative test procedure is to steadily increase load - using a winch or ram - attached to a load cell. The advantage of steadily increasing load is that you can try to pinpoint the load threshold where the F8 knot jams. It is currently theorized that the jamming threshold of an F8 knot is around 4.0kN (in EN1891 low stretch ropes). It would be interesting for you to also run some tests using steadily increasing force to zero-in on the load threshold where jamming occurs. This type of testing would be done with F8 knots tied in different geometric orientations. You would need to run tests in both EN1891 low stretch rope and compare to EN892 dynamic rope. Results should be compared... ... If you don't understand 'chirality' - I recommend that you visit my knot website at this link: www.paci.com.au/knots.php Download and read the PACI 'Knot Study Guide'. It is very detailed and explains everything you need to know... Mark Gommers May 2021
Thanks Mark for more comments, As I already mentioned in previous comment I'm aware that there are 4 variations of fig 8. But since two versions are just mirrored I did not expected that to have an effect on how the knots jam / load. The way I designed my experiment is that I always tied one control (good) knot on one end and a variation on the other end. I also did randomized the position where the good knot goes - sometimes on the anchor, sometimes at the bottom. As I expected I didn't found any significant effect of position swap - because the rope is so short and the impact indeed travels very fast. However as shown in the video I found huge correlation of how hard it is to untie the knot if the knot is: Tied incorrectly - having overlapping strands Is loose in the beginning And the most interesting - if the load strand goes on the top of the knot. What I also noticed that how easy to untie also depends on the thickness and hardness of the rope. If the rope is very worned out and soft the knot will jam much more. Later on I received a lot of comments from people saying that since they changed the way they tie fig 8 they no longer have trouble untying it. And I did some experiments where my friend 95kg made a super big hard fall and I untied the knot without any big trouble - he was always using bowline before because he was having trouble with his fig8 knots. And to finish I waned to say that yes, I'm not a certified testing lab and can not make repeatable consistent experiments. But the findings were enough for me to satisfy my curiosity and maybe spark an interest for someone with better equipment to research this even more. Thank you for sharing learning material - I think I'll find a lot of use for my future videos.
Very helpul and clear instructions, thank you. Just a small note: Never use screwdriver for opening stubborn knots, even climbers should have a marlinspike in their toolbag :)
Thanks for the great video! I generally tie clean figure 8s without any twists and tighten them and mostly don't have trouble untying them, but I'll need to check where the load line ends up. I had never paid attention to that. I'll comment on the Yosemite follow through. I use that and do find that it makes untying easier. I leave a somewhat bigger loop before the follow through, giving more rope to grab when pulling it out. Also, it would make a big difference if the knot is still tied to your harness. This gives something to pull against so you are not just pulling on it with your two hands. You would be able to generate much more force. That being said, I'll have to compare the follow through with a knot with the load line in the middle. Thanks!
One of the most interesting didactic climbing video ever! Thank you so much. I would like to see the difference in rope breaking with different knot variations...
That's super interesting how weird the figure of 8 ends up when it's not tightened properly 💡Not gonna lie, messy and not well dressed knot is def one of my pet hates. Equally interesting too how much of a difference it is to have your loaded strand in the middle instead of on top 👌
It is very interesting, in speleology, the reverse method of knitting the figure of eight is used, when the cargo end passes over the top of the node and is also quite strict, but there are completely different operating conditions
Some people are trying to solve Rubik's cube on time... climbers tries to untie figure 8 knot :D Thank you for video, really helpful content, as always :)
I also noticed that if rope end is worned out it makes it harder to untie as well... But would need more experiments to prove that ;)

Makes sense to tighten before loading, because at least you get to control the final shape of the knot before the load tries to change it.

@@HardIsEasy 🤣
Me too, on all counts.
Ive only been climbing for 7 months. Ive never had an issue untying my double figure 8's. But ill thank the gym staff for correctly teaching me how to tie the double figure 8
Awesome video! I always have problems undoing my Figure 8, especially after a couple hard falls. Tried reversing my follow through as well as snugging up the 4 rope ends out of the knot during the last few climbing sessions since watching this video. It was so easy to untie!
Amazing I love people coming back to say that it actually works for them as well! Thanks!
Man, this is a gold tip! Thanks for that!
I like these tests, I like the scientific approach!
Excellent video, again. There is always room for something new, even things as 'basic' as knot. Thank you
Thanks a lot Kuluar!
Thank you Hard Is Easy!! Love your videos. This Climbing Human will definitely make sure to have dress my knot, have load line thru the middle of knot, and not have any crossed strands.
Thanks ;) let me know if you see any actual difference
In the Toyota Lean production system the main goal is to keep the ropes tight. Stay organized, stay clean...to see the problem, the missing things, or any defect. But here is the real meaning of this sentence. Keep the rope tight to save your life and make easier your life to untie a knot after a fall.
Just a tiny differences, but at the end the difference is reeeeealy huge. Thanks man!
Thank you to for nice comment !
Would like to add that few people know or bother to tie a "dressed up" figure of 8. This should also reduce time of untying. You do so, but it will be beneficial to the community to show how to do it. Thank you for the videos.
Yea I made a follow up video on this ;)
Thank you I have been teaching this but not knowing why it worked. Well done on a fantastic video!!!!!
Those details make a climber pro! thanks for sharing
Something to note: you untie knots correctly. You push the loops of the knot apart.
Most people I teach (I'm an instructor) try to pull the tag end or load strand out of the knot, rather than pushing the loops up, over the the two strands of rope where they exit the knot.
Great video! I hope people watching notice that you push the knot apart, rather than trying to pull strands out. It makes a huge difference in untying.
yea that's a really fantastic comment! I need to plug this in one of my vids...
Nice Work, amazing how a very common thing can reveal some new stuff ! Thank you for your work !
Haha thanks as well ;)
Thank you for all the time you take making videos and testing gear
Mind blown! Very informative. I've been climbing for 20+ years. Turns out I'm still a gumbie 🙈
Great video! I would love to see a video on the figure 8 knot vs the old school sport bowline. My wife and I prefer the sport bowline.
If you are using one of the safe variations of bowline - it's a good knot, just keep in mind that most people don't know how to double check it ;)
You have a very “Alexander Supertramp” vibe. In other words a pretty chill, cool dude.
Great experiment. Shows that there is depth to even simple systems. Thanks.
Good job! Thanks for taking the time (and the ropes) to do the experiment. Language is so accessible (not a science nerd conversation)....sweet!
Thank you as well ;)
16:56 how to properly tie off the figure 8.
That is why i rather use a bowline ... yosemity or double
but thank you for the info how to make the figure 8 easier to untie
Yea, bowline is fine, just be aware if your partner actually knows how to check it ;)
Yosemite is actually easy to screw up if you tighten in the wrong order. Best thing about f8 is that it's essentially foolproof AND incredibly easy to inspect.
Have a look at scotts locked bowline. Super simple, fast, and one of the most secure bowline variants. It's kinda absurd that it wasn't discovered and used decades ago
Charlie Palmer This was new to me (have been using a regular yosemite finish). Do you see any advantages of ”scotts” compared to ”lee’s” ?
@@johnliungman1333 Scotts is just super simple, and also very secure.
www.paci.com.au/knots.php has a 77 page write up on loads of variations of bowlines, the very last page has the secure variants
Love you bro. Awesome channel, I really appreciate your such hard work on such quality videos, which can make us easily understand.
Excellent info, thank you for putting this much effort and quality into sharing this information! New subscriber!
I will still stick with my bowline with double stop knot, but this is really interesting, I never thought that there was 2 ways to tie a figure of 8 knot. Thanks for the video !
Haha your welcome ;)
Amazing. Thank you for doing this. I never thought about the load-line going on top or in the middle before.
Great work!
I just use a doubled bowline knot. Never hard to untie ;)
Yes, me too. Since I don't do competitions (where a figure 8 is required) I learned it. It convinced me that they use this knot to secure huge ships and are still able to easily open it :)
Works like a charm - even with the sticky ropes in climbing gyms.
Thanks a lot! So elegant way to explain what I couldn't understand!
Dude, this is awesome. Now I can explain to my friend why his neatly dressed figure eight still binds up!
Great video! Thanks for all your hard work!
Absolutely great made and entertaining. I was not sure if I could learn something when I started the video and than boom - excellent and thank you for sharing :)
Boom ;) glad I didn't wasted your time ;)
And here I was blaming the knot for being difficult to untie, when it was mostly my fault. But I think I'll still use double bowline, just because I think there is less room for stupid errors when doing it correctly. But I'll definetely try to check which variation of figure 8 I do when tying in. Probably both.
Anyways, I think Your channel is evolving in the right direction, from being just another climbing vlog to seriously interesting and useful content. Keep it up! ;)
Thanks Buddy! Amazing coment!
Bowline is great, but lots of bowline users neglect the fact that a lot of people don't know how to double check it ;)
So if your partner does - amazing... keep in mind that there are 5 bowline variations and some random partner might just nod - yea yea good climb, but actually don't admit that he's confused looking at your knot ;)
Brilliant. This video should be sent to all climbing instructors ASAP. :-)
Haha, yea I'm curious why a lot of them say you need load strand on top... But I'm gonna check on this more ;)
Great experiments and nice conclusion . Thanks
Great video, thanks for all the work you put into it!
Hello Ben - thanks for your time and effort in producing this video, it is appreciated.
I would like to provide some critical feedback - which I am providing in good faith.
The first point I would like to make is that there are in fact four (4) possible geometric orientations of the #1047 Figure 8 eye knot.
I'll refer to it as an 'F8' from this point to keep it short and simple.
You stated there are 2 different orientations - when in fact there are 4.
I note that you have a natural tendency to tie your F8 knots in 'S' chirality.
Hold your F8 knot adjacent to plane mirror and you will see a reflected image showing opposite ('Z') chirality. Chirality is found everywhere in nature - for example, humans all have a left hand and a right hand. You cant flip, turn or rotate your left hand to convert it into a right hand...its always a left hand. However, you can hold your left hand adjacent to a plane mirror, and the reflected image you see will appear as a right hand!
You can perform this exercise with any hand tied knot. Tie a knot in your natural (preferred) way and then hold it adjacent to a plane mirror. You will see a reflected image with opposite chirality. Note that the reflected image is equally valid.
I am of the view that you are unaware of the chiral nature of knots - and that the geometric orientation of your knots are influenced by your dominant hand (and also influenced by how you first learned how to tie an F8 knot from your instructor - or if self-taught from a book).
Given that all of your F8 knots have 'S' chirality - it leads me to think that you are left-handed? That is, left-hand dominant people tend to tie their F8 and 'Bowline' knots with 'S' chirality.
Right hand dominant people tend to tie these knots with 'Z' chirality.
The second point is that you should not mix two different knot geometries in one test. There is a rule in testing which basically states that you should only test for one variable at a time - and you also need a 'control' (ie the 'scientific method'). Now - I am fully aware that you are not an accredited test lab and therefore are not obligated to follow the 'scientific method'. However, I urge you to only test one variable at a time - don't mix two different knot geometries in a single test.
Example: In in test, tie two (2) identical F8 knots - in other words, both knots have exactly the same geometric orientation.
Don't have one geometric orientation at one end and a different geometric orientation at the other end.
Perform your dynamic drop tests as you have been doing (although standing on a table isn't exactly a 'safe' technique!).
Note that you ideally should attach a load cell to measure the peak load reached - otherwise we have no idea of what force you are achieving (without a load cell - its not possible to know with precision what peak load you are reaching). This makes it harder for others to try to repeat your test results...
If you tie two identical F8 knots - you will be able to compare one against the other - which will provide you with opportunities for further insight.
Note that you may find one knot harder/easier to untie than the other.
This is due to the fact that you have a stationary anchor at one end, and a moving load at the opposite end (there will be a short time delay in transmission of force along the line...it won't be instantaneous - force doesn't propagate at the speed of light).
You should take careful note of which knot is easier to untie relative to the other - and report this.
Perform the same test (ie repeat) with an F8 knot tied with different geometric orientation (ie both ends of the rope tied with identical F8 knots).
After the test, take note (again) of any differences between the two F8 knots.
For example, do you note any difference between the two F8 knots?
The last point is that you are performing dynamic drop tests - where the knot specimen is subjected to a sudden (very rapid) increase in load.
An alternative test procedure is to steadily increase load - using a winch or ram - attached to a load cell.
The advantage of steadily increasing load is that you can try to pinpoint the load threshold where the F8 knot jams.
It is currently theorized that the jamming threshold of an F8 knot is around 4.0kN (in EN1891 low stretch ropes).
It would be interesting for you to also run some tests using steadily increasing force to zero-in on the load threshold where jamming occurs. This type of testing would be done with F8 knots tied in different geometric orientations.
You would need to run tests in both EN1891 low stretch rope and compare to EN892 dynamic rope.
Results should be compared...

If you don't understand 'chirality' - I recommend that you visit my knot website at this link: www.paci.com.au/knots.php
Download and read the PACI 'Knot Study Guide'.
It is very detailed and explains everything you need to know...

Thanks Mark for more comments,
As I already mentioned in previous comment I'm aware that there are 4 variations of fig 8.
But since two versions are just mirrored I did not expected that to have an effect on how the knots jam / load.
The way I designed my experiment is that I always tied one control (good) knot on one end and a variation on the other end.
I also did randomized the position where the good knot goes - sometimes on the anchor, sometimes at the bottom.
As I expected I didn't found any significant effect of position swap - because the rope is so short and the impact indeed travels very fast.
However as shown in the video I found huge correlation of how hard it is to untie the knot if the knot is:
Tied incorrectly - having overlapping strands
Is loose in the beginning
And the most interesting - if the load strand goes on the top of the knot.
What I also noticed that how easy to untie also depends on the thickness and hardness of the rope.
If the rope is very worned out and soft the knot will jam much more.
Later on I received a lot of comments from people saying that since they changed the way they tie fig 8 they no longer have trouble untying it.
And I did some experiments where my friend 95kg made a super big hard fall and I untied the knot without any big trouble - he was always using bowline before because he was having trouble with his fig8 knots.
And to finish I waned to say that yes, I'm not a certified testing lab and can not make repeatable consistent experiments.
But the findings were enough for me to satisfy my curiosity and maybe spark an interest for someone with better equipment to research this even more.
Thank you for sharing learning material - I think I'll find a lot of use for my future videos.
Best answer! The study guide is very useful to understand the "topology" of the F8 knot. Thank you!
Thanks!
Thank You as well!
If you want to continue using the figure 8 knot use the "Wagner" variant.
My personal recommendation: the double bowline.
A greeting
Very helpul and clear instructions, thank you. Just a small note: Never use screwdriver for opening stubborn knots, even climbers should have a marlinspike in their toolbag :)
"Hi there, rock climbing humans..."
4 seconds in and love this video!
Thanks for the great video! I generally tie clean figure 8s without any twists and tighten them and mostly don't have trouble untying them, but I'll need to check where the load line ends up. I had never paid attention to that. I'll comment on the Yosemite follow through. I use that and do find that it makes untying easier. I leave a somewhat bigger loop before the follow through, giving more rope to grab when pulling it out. Also, it would make a big difference if the knot is still tied to your harness. This gives something to pull against so you are not just pulling on it with your two hands. You would be able to generate much more force. That being said, I'll have to compare the follow through with a knot with the load line in the middle. Thanks!
you should get in contact with The SlowMotion Guys to record the fall and clearly understand what happen to the knot ;)
Interesting idea :)
Thanks for the hard work !
One of the most interesting didactic climbing video ever! Thank you so much. I would like to see the difference in rope breaking with different knot variations...

Enjoy :D
Thanks for this very instructive video.
How you tied the figure 8 in the end is exactly how I was thought as a complete beginner for toprope course. Guess I'm a ninja 😂
That's super interesting how weird the figure of 8 ends up when it's not tightened properly 💡Not gonna lie, messy and not well dressed knot is def one of my pet hates.
Equally interesting too how much of a difference it is to have your loaded strand in the middle instead of on top 👌
Yeap I was surprised as well... But when I saw weird stuff in real life it just confirmed that the knot needs to be dressed well
Really good video, you did an awesome job and explained it really well!
It is very interesting, in speleology, the reverse method of knitting the figure of eight is used, when the cargo end passes over the top of the node and is also quite strict, but there are completely different operating conditions
I cannot wait seeing the second part, but incidentally I've discovered I use to do the figure of eight with the long line in the middle!
Trying to figure out some extras for the 2nd part ;) and big thanks for the support ;)
Some people are trying to solve Rubik's cube on time... climbers tries to untie figure 8 knot :D Thank you for video, really helpful content, as always :)
Well it was during lock down... so you know... :D
@@HardIsEasy for science!
Great job, nicely done, its often about tiny differences, not only in climbing.
Thanks Marcus!
Thanks for putting in all the work, I definitely learned a few things
Haha me too ;) and thank you as well ;)
Great, great work, my friend. Respect
