Your work is truly important. Ashley wrote his famous book of knots in the late 1930s. He used mostly 3 strand hemp cord since nylon was still in the laboratory until it got its start in women's hosiery and parachute cord during the war. Needless to say, twisted organic fibers behave differently than braided synthetic fibers. So certain properties like a tendency to jam with organics may not be as severe with synthetics, and other knots than seemed to be secure with organic rope will loosen or creep with synthetics if the load is cyclic. The old adage about tied, dressed and set is always good advise, but you now have the ability to inspect knots under increasing strain to see how they change shape under load. Some of these knots seem to get lumpy rather than simply smaller under load. It would be interesting to see how loose knots can be upset and change their form under load. Some well tied knots may also have this property. Then, there is the difference between kernmantle and double braided rope as well as nylon versus polyester in typical climbing ropes. HMWPE or Dynema behaves differently then we are used to.Yes, I left out the aramids, but this is post getting too long.

The difference between a knot and a bend is kinda vague and often misused, but basically a knot holds its shape on its own. A knot used to tie two rope ends together (or the opposite ends of the same rope) is called a bend. A figure-8 is a knot. But if you tie two ropes together using a figure-8 so that the ropes exit on opposite sides of the knot, then that is called a flemish bend. An overhand knot is a knot, but when used to tie rope ends together its called an overhand bend. A hitch is a knot that falls apart if you remove the thing it's tied around, like a clove hitch.

Here are a few thoughts: First establish a baseline rope strength by breaking some unknotted rope attached to largish diameter anchorages, e.g. a "bollard" or "capstan" type anchorage, using a several round turns and a high strength tie off. Then test knots in a way that simulates normal use cases (i.e., bends to join tails, loop knot to form loops), but avoids tight radius attachments ( use smooth but large shackles instead of carabiners). Now that you've got a estimate of rope strength and knot efficiency, apply the knowledge to more "real life" configurations and loads: use carabiners where appropriate, use drops to simulate climbing falls, and some sort of "slackline simulation" by dropping a load normal (perpendicular) to a tensioned line anchored with the knot in question.

@trollmcclure1884 2 жыл бұрын

Yes, a bollard is a must. They should divide the failure points of bends not by 2 but rather 1 and something because there's clearly two ropes and when the bend slips, the other side gets shorter and pulls the rope over the edge of a carabiner. It would be better to call the test unvalid and do it properly

@brettknoss486 Жыл бұрын

I'd look at securing the rope with clamps to ensure the rope fails at the knot or at a random point in the rope. I would also like to see the Ashley bend tested.

@trollmcclure1884 11 ай бұрын

@@Jayizzy433 you'd still benefit from unbiased result using a bollard. Unless you make slings between two carabiners using these knots just like them. Otherwise it's a bogus claim. Alpine butterfly should be tested using the loop, not the sides. If they break in the knot then the test is valid. If it breaks over the edge of a carabiner then using a bollard would be better to test the strength of the knot. Still interesting to get an answer just when I'm doing rope access after a year or so. We use only figure 8 and Alpine butterfly so that everyone is familiar with it and can check the anchor and trust it.

As a lifelong knot nerd, I love the ideas you're proposing. The classic knot bible, Ashley Book of Knots (ABOK), makes lots of prescriptions on how knots should be set up and modified for different circumstances. Since it predated 1) synthetic materials and 2) the modern climbing/slacklining movements, I would love to see its dictums tested in a contemporary context. The possibilities are endless. For example, the sheet bend in this video broke easily. What about a slipped (quick release) sheet bend? Is is so weak that its convenience is almost irrelevant? Or a doubled sheet bend, which I've seen mariners use to tow vessels. Does that extra wrap make up for all the slippage? Or stopper knots. Do the fancy ones actually perform better than a simple overhand in practice? The possibilities are endless. ABOK is also just a delight to read about the different ways professions used knots, which kinda keeps with your vision to expand the channel beyond straight slackline content. I could see content based around "does XX historical set-up actually test well, and what could we learn from it?" Super excited for any of your future knot vids!

@solandri69 2 жыл бұрын

@@1-t254 I'm a fisherman. I looked up the double fisherman knot and it looks like a simplified uni-to-uni knot, which is widely regarded as the best quick way to join two fishing lines (near 100% break strength). It works because as you pull it tight, the wraps cinch up and clamp down on the other line. And you get a double finger-puzzle effect spreading the load over a length of line, instead of concentrating it at a pressure point which can cut the line. In the uni knot, the wraps go around both lines. In the double fisherman the wraps only go around the opposite line.

Thanks again, great video. Here's an idea: Put the rope through a pulley on each side instead of directly through a carabiner. This way the load on each side of the carabiner would be equivalent in this configuration. (Rather than the knot side of the rope stretching more than the other, which puts differential stress on each side of the carabiner). This would also achieve a higher bending radius which might be more useful when testing knots, rather than having the carabiner impact the results. Essentially it easily takes a variable out of the equation.. Just an idea! Thanks again for sharing! Useful for everyone that literally puts their life on the (a) line every day especially!

@DavidRichfield 2 жыл бұрын

As others have pointed out, the sheet bends here were all tied the wrong way, with the working ends on opposite sides of the knot, but that shows that it's a knot that should be approached with lots of caution. A zeppelin bend doesn't seem to have a "wrong way", and it's easy to undo. A carrick bend even more so. If you urgently need to connect two ropes and you don't mind having to cut the rope later, do an EDK or a double fisherman's. The EDK is the easiest bend to tie, and it doesn't deserve its bad reputation, as long as you leave enough of a tail for it to capsize once.

@arzthaus Жыл бұрын

I like to tie an EDK and then use that knot to tie an alpine butterfly. That way it's much easier to untie under load

@Mike_Rogge 6 ай бұрын

The Carrick bend does have a wrong way, the method taught in the 13th edition scout handbook puts the loops in opposite directions instead of the same, which allows the knot to "unwind" in the same manner as a thief's knot. This was tested by me in 3/8" nylon sailing line, 1/2" decommissioned climbing rope (material unknown, looked like static), and assorted sizes of manila and sisal. Only the sisal didn't slip, which is irrelevant as sisal never slips and breaks easily.

I think the single knot video idea is genius, it really turns all of this time and energy y’all put in into a resource for everyone, like all of us nerds who would watch anyways and broader to people who are just trying to learn a knot while simultaneously exposing them to the deeper and more nuanced things to consider around rope and knot tying. Personally I can’t wait to watch some of you guys run individual knots through a battery of different tests.

Loving the end screen disclaimer! Re: rope strength differences. Yeah it might be differences in test setup, but it _is_ possible to have the exact same diameter of rope made of the same materials be stronger. Two ways: 1) the weaker rope may have a thicker sheath, but thinner core. 2) the stronger rope might have longer polymer chains with less defects in the core strands.

The proper use of a Sheet bend is to tie 2 ropes of different Diameters. Like a smaller line attached to a ships docking rope. It would be cool to see the knot tested in its correct function. the larger Diameter forms a bite while the smaller diameter rope / cord circles around it. It can also be used on Tarps and sand bags (where a bite is created from the tarp or sandbag material) Thanks for sharing another great video!

The 9.8 kN MBS value is exact what the technical standard EN564 requires: In Europe Edelweiss is more a budget brand, so I expect they produced a rope “good enough” and then simply save money by testing not more than required and selling it labelled with a probably too low but save MBS value. But it has to be tested according to the same EN564 test procedure like the Edelrid, which defines the way of attachment.

This was awesome! You're underestimating how valuable this info is. My takeaways? The good knots are pretty good, and all pretty consistent with each other. That the sheet bend is an old knot that might work great on high friction old rope, but looks like not so good with modern line. That the bowline is underrated. That the figure 8 is great, but maybe I should be looking at fishermans for slippery rope. And finally, that the "make a loop thing" of course really does work, and because there's two lines is going to be stronger than the max breaking strength of a single line...even with the losses of the knots and the hardware. See? I learned a LOT and I'm pretty slow!

I Have always been dubious of the sheet bend anyway which seems to be confirmed by the video. However, I was taught (rightly/wrongly?) that a sheet bend is used to tie dissimilar diameter ropes with the large rope folded over and the smaller rope forming the wrapped part of the knot (can go round twice for a double sheet bend). If the ropes are the same then a square/reef knot should be used, although this is another dubious knot for tail slippage! Good to see the easy-to-tie double fisherman do so well.

Great video! The sheet bend appeared to be tied differently than the way I was taught. Both bitter ends should be on the same side of the knot. Perhaps they would break rather than slip. Perhaps (k)not?

What prep was done to the knots prior to testing? Several seem like they're not completely dressed or pre-tensioned and may even spill. I'm no expert on knots so I'm not implying anything is wrong, just asking what the process was. Thanks.

I'd be really curious to see how the normal alpine butterfly holds up when the loop and both ends are pulled in different directions Also, super keen for the drop tower knot tests!

@hugbearsx4 2 жыл бұрын

I wonder whether a test scenario like this could be setup or not, in a manner that would make the results *relevant* for the real world. The results of such a test would depend greatly not only on what force is applied on the loop, but also on the angle of that force relative to the main line. But the most important variable is the length of the lines from the knot to the attachments. That length influences the angle of the main lines to the direction of the pull which, in turn, GREATLY affects the resulting force in the line - and that angle would also vary during every pull. So... which set of parameters would be relevant in terms of realism? There are literally an infinity of such sets of parameters.

@@hugbearsx4 I agree but I think that makes it all the more interesting for me, I'm really curious to see how the knot behaves in each of those scenarios and therefore get a better understanding of the potential use cases and limitations of it. As for how you'd test it, that's ultimately up to Ryan to decide but you could possibly test it in the following 3 orientations: 1. Loop and each of the ends pulled with equal force at 120° angles to each other (though I understand that that may not be super easy to set up). 2. Loop and one end pulled in one direction with the force distributed across them, and the other end pulled in the opposite direction. 3. Loop pulled in one direction and the ends pulled in the opposite direction And again, the point isn't necessarily to reproduce accurate results to what you might see in the real world, the point is to get an understanding of how the knot behaves under different scenarios.

That was NOT a sheet bend, a proper sheet bend is tied so both ends come out on the same side. It's such a common mistake that I think nobody should use it at all.

@liambennett9323 2 жыл бұрын

I feel that the sheet bend result might be because it was not being tested in the usual use case, which is to the best of my knowledge is specifically to join a thin rope to a thick rope, where the thick rope forms the basic loop. This might mean that the knot was not tightening properly under load in your test as the two ends of the rope were tightening at the same rate; whereas when set up correctly the thinner rope would tighten around the larger one as well as onto its own running end, preventing slipping.

He tied the sheet bend with the working ends on opposite sides of the knot, which is considered an error.

@Catcrumbs Жыл бұрын

@@moodywonka I can't find any empirical data on the subject. The sheet bend stands out in this video as having a very poor result, which does not seem likely to be a true reflection on the bend, considering its long-standing use. Just as a 'small' error makes an inferior granny knot of a reef knot, I think it's very possible that the sheet bend would do much better if tied conventionally.
