Find out if tapering splices is important in our last dyneema video kzfaq.info/get/bejne/os55g8h7s73YqHk.html and don't forget the blog has more information than I can fit in a 16min video www.hownot2.com/post/soft-shackle-comparison Check out our new store! hownot2.store/

For those interested, the "disks" on the stopper shackles are made from 6061-T6 aluminum, and were then coated with Cerakote , which is a ceramic based bake on paint that is very slippery to try and reduce any friction that might be generated by the disk itself.

The numbers were absolutely organised enough 🙏

Enjoyed creating the test pieces and learning a lot more in the process working with you on this video. Hopefully we can do another Dyneema rope project , i have ideas 😁

The well laid out tables were super good enough for dealing with so many numbers even on a phone screen.

Perfect about data, well organised and understandable

Worked as a yacht rigger for many years and its funny, the load bearing capacity of dyneema whether chinese or brand name is almost never the cause of failure. What it comes down to is the chafe and uv resistance of the covers allowing for individual fiber breakage. The only concerns when it comes to dyneema tend to be exposure of the core and breakage of fibers due to wear rather than the overall load handling capacity of the fibers because its extremely rare for a dyneema line designed for a certain application to even approach its failure point without degredation of the cover whether from uv or chafe, its just so strong. Creep is a relative nonissue due to the stretch characteristics so you can avoid point loading in the individual strands given your sheave diameter is correct for the size line you are using. Dyneema is a wonderful line that if used properly can be applied to most loading conditions in all environments.

Living near DSM where dynema is made. Gheh feels a bit special to see this stuff all over the world 😄

A small correction for the samson amsteel blue. Amsteel blue is made with sk78 not sk75. I know because i work for Samson. Sk75 was phased out of amsteel blue a few years ago before we even made the soft shackles. And specifically for amsteel-blue we only use sk78. It may seem like a minor difference but there is a difference between sk75 and sk78. Sk75 is slightly weaker and lower quality then sk78. Felt i needed to point this out.

This was super interesting! I make soft shackles all the time professionally (I'm a marine rigger). Curiously I honestly can't remember seeing any of these styles in the field where the two strands are not spliced through each other, and rather two eye splices. Especially not one with an aluminum plate! Great to learn about. In any case, if you have any interest in a follow up vid testing a completely different design that we use in the sailing world, I would be happy to send samples and I can reach out via email. I would also be very curious to see how our style shackles hold up, and I've never seen one break, but we aren't even coming close to swl of just just the raw amsteel in our sailboat applications. Anyways, another great vid! Drop me a reply if you'd like me to send an email!

I think the way you presented all the numbers made it easy to keep track of. Super good enough

Love the raw data along with the commentary. Keep doing exactly what you're doing. Awesome job.

Very well organized, excellent information. My biggest takeaway from this video is that home made soft shackles, if done properly, are stronger than the rope from which they are made, which gives me peace of mind that the shackle is not the weak link in a rigging system.

these charts are faaaantastic. i remember watching a few of your videos a few years back that were big colourful messes and I was very confused. these are super easy to read and grasp the information that they're trying to portray

Thanks to you I've started using my own form of soft shackles. Not in a life-supporting scenario, but to attach the stirrup to my paraglider. It only needs to be strong enough to let me push back into the seat of my harness so I just tied loops out of Harbor Freight Paracord using double-fisherman's bends. Again, its just for leverage, and if it fails (or I forget to setup my stirrup) I can still shimmy back into the seat so... Super Good Enough. Thanks!

The amount of data is good for one Video. It was easy to follow and understand!

Nice thorough test. For me, as long as the soft shackle is stronger than equivalent eye-to-eye I'm happy because that will reliably be the weak link.

Super good enough display of the numbers. Everything was straight forward and easy to understand.

Many numbers is super good enough :) Apart from your stellar personality and hot bod, we're here to see the results of all the amazing tests we would otherwise never get to see.

The max sk99 6mm with a button knot, this video, and the data presented in this video were all… super good enough!

SK's lower than double performance seems like it's related to the weave. The large weave is making larger bend differences, more tension on individual fibers. Would be interesting to have the MSRPs in the data table. The SK seems super good enough if it holds up over time; might be a good value even if it doesn't last forever.

Mass numbers are super good enough and the organisation style was also super good enough.

I definitely appreciate the numbers, I like the context as you go.

I am a fan of numbers and spreadsheets and formulas, so I love all the numbers. Especially in the context of break tests, which is so inherently about numbers.

"chineema" I have a new word in my vocabulary. Thanks for that. (& the really useful tests)

liked this video a lot, the numbers are very clear and show the diferences in qualities very good. I love this dyneema videos

The air quotes are strong with this one.

I liked the charts shown side by side made for easy comparison keep up the good work

Great to see all the numbers!

The organization was great! Crazy to see the unbreakable sample

Data is readable and clear

I admit to buying the cheap stuff for soft shackles, aiders, other general work duties.

Liked the way the data was presented well done

I had no idea how good soft shackles were before watching your videos. I personally like the number data.

Great amount of data. Easy to understand!

3:58 "This one especially (knot)" ... I see you

Numbers were well organized and easy to understand. 2 refuse to be broken samples lol. They are TO Good Enough 🤣

loved it understood it all. great info well delivered keep it up!!!!

Numbers in the video were great!

Ok great the testing regime you are committing to, to find the ultimate shackle but I would like to offer some input on this. The first information in regards to the shackle retaining twice the strength from tying a knot to prevent the noose coming off. Isn’t it fact that the knot regardless how well it’s tied is just that a knot. When your shackle is being loaded the noose will be forced down onto the back of the knot.. your break loading point.. during the application if you are under estimated in capacity of your shackle the load will continue apply on this knot until it either gives or friction is that great it will melt and fuse the throat of the shackle always failing in the knot. Essentially the knot is still your problem in a serious application.

Everything beautiful 😍

Thanks!

Great content as always, thanks! I’d love to see the results in a graphical format too, it would make it easier to compare I think.

You can buy really thick Amazon shackles that are way stronger than my winch line, so there is no point in buying them from a 4x4 brand for me.

If they splice at the noose, so there's double the strands at the weak point...would this help?

i like the numbers on the spreadsheet, but i wish it would stay on the screen a little longer, otherwise great video and i appreciate all the work that goes into all of your videos!

Try testing under water, it might keep it cooler so stronger, just a hunch

Well organized

The disk was interesting. Would like to see how long it takes to build. The logical extrapolation is that you could use anything as a stopper. The first thing that popped in my head was an old style lanyard ring although it would have to be a long soft shackle to get the loop over it. Or a d ring shackle, you could slide the rope through and then attach the shackle. Adding metal bits to a soft shackle is undesirable in most applications, but like the disk and sailing somebody might find a use for it.

It is very slippery, it slides out of cam cleats pretty easily. It has next to no stretch once tensioned, and is spectacularly strong though.

Hey Ryan another great video, The takeaway for me is that soft shackles do not introduce a weak point into the rigging even if you use chineema. I do have a question though and that is how polished are your shackles on the rig, shackles for uhmwpe ropes should be highly polished in order to minimize friction and I wonder if that friction is accountable for at least some of the failures.

all good , im seeing if i want to make/use these shackles close to max spec that ... i use the crown knot plus pull the knot tight mechanically to reduce any movement/ heat production in knot when is in use - loaded .. will give more reliable higher breaking shackle ... BTW why cant you go 3:1 and test to 150Kn ? etc. etc ps [hope everyone had good eye protection for the aluminium shrapnel from the discs] ; ]

Thanks, awesome information 👍🏼

I came for the numbers, but stayed for the "chineema"!

numbers are fine

How about the price comparison??? Anyway... The chinese seller tend to marking up the size or reducing the material for a specific size. I've tried comparing several different seller. The good way to compare them is to weight it on a specific length.

Good amount of numbers :)

My favorite rope is Amsteel Lite. Delicious

i was able to follow and appreciated it. but i am also a scientist.

I liked those numbers!

Organised enough!

As a sailor I would really be interested in the same test but with the dyneema brands being in the tropic sun for a year or two. And/or with normal use after some time. How do they stand up to degrading?

This was wonderful

Can you link to the circle things and/or the way to make a soft shackle with them?

I think colour coding in the tables would go a long way. Eg. Green for the strongest of the three, red for below MBS/prediction

One question would interest me here: What is the maximum tractive force for testing the system? Thank you

I watch your videos and they are a great help. Where do you get your Dyneema rope? Awesome Break down. 🤛👍👏👏👏👏

dont know much about climbing but would it be possible to pad the dyneema noose in order to protect it from being the weakest point, or is it even worth doing/trying given that the loads are already way above what is to be expected?

Love the numbers! Strange how the Amazon stuff is both stronger and weaker than the name brand. I purchased some softies off Amazon likely made from the cheap stuff so I'm now curious what it breaks at.

What if you take 3 minute or 5 minute “breaks” every 10KN so the rope has time to cool? Would that give you a higher break strength rather than pulling right to 40-60KN?

My gut instinct is getting a larger hydraulic but clearly if you need something to hold more than 40kN, thats something you need to engineer on your own

How about some graphs to show the data at the end?

Can you test the Behelfsseilklemme from Petzl on the rope and after them a rope test.

I'm very curious how this material would work in climbing devices? Wonder who could possibly test this 🤔 😁

I enjoy the numbers. I want all of them =) For me the format could be even more concise: more pulling and data - less talking.

Is the data from this and past videos in a public spreadsheet anywhere? I would love to do some analysis!

How much is 1 kn on a static load? I’m an arborist and really like the break test numbers you provide. They help me better understand the loads and limits of my rigging and climbing gear.

What was the first sample you refused to break?

Utrzymał by startujący myśliwiec, niesamowita wytrzymałość 90 kN 🤯 It would hold a fighter taking off, an incredible strength of 90 kN

So button soft shackles seem far superior.

I love all the numbers, but then I'm one of those damn engineers. So as my wife will attest I'm not normal.

What ever went on with the drop tower? Idk u did start new channels maybe im lost now

Not nearly enough numbers. I don't see any elapsed times, temperatures, humidity levels, or elevation figures. The original length and mass of the samples, along with weight retention, should also be given.

hot damn!

This soft shackle work load is Fun to watch Go to 6 min kzfaq.info/get/bejne/bNuCepdlyretYok.html He has a LOT of jerk and pulls with a Lot of heavy recoverys.

Bla bla bla

Deep down we're all Nerds, the numbers can sometimes be the best part. You guys got the data graphed out super good enough. love to see it Fun Fact 0.827369kN = My Fattass

All those numbers mean shit to us normal ppl. I can't be bother sitting down with calculator because of your ...
