I only use quintuplet fisherman’s. It’s how I join 2 60m ropes to make a single 70m rope

[@snigwithasword1284]

[@ryenschimerman2127]

Knot funny.

[@Mesenteric]

I’m a firefighter who uses rope a lot, I’d love to see a video about rope rescue and the like. The testing is very interesting. Great stuff.

[@Netbug]

If there's one thing this channel has taught me, it's if I ever go climbing I'm making a climbing chain out of steel shackles.

[@orc_gunslinger]

So when you fall, your body absorbs all of the energy, and you can pass the steel on to your children

[@Netbug]

@@orc_gunslinger Yes. And I want it to be so heavy that it exceeds its own rating and snaps.

[@johngo6283]

Great way to address the long-standing concern that with so-called tech cord you always have to use a triple 🐠🐠🐠

[@zecuse]

For those that don't realize it, a fisherman knot is just an overhand knot tied around another end, be it's own opposite end or another line's, followed by tying the same thing again with said other end.

[@NPC-fl3gq]

Truly you are doing gods work Ryan 🙏

[@dawntreader7079]

Ryan, it would be interesting to use a laser thermometer during the stress test, hold the beam on the knot area as you pull. You'd get a pretty accurate reading on how hot each material gets when stressed. The comparisons would be interesting data. Just an idea.

[@goldensunrayspone]

the issue is that the knot moves along the rope, and it's not safe to have your hands anywhere near the rig while it's break testing (they stand behind a metal plate while running the tests) it might be better to use a thermal camera

[@marknorton3951]

The laser bit of contactless thermometer is just for rough aiming. The measurement is still done through infra-red, across an area projecting as a cone from the device sensor. It’s not easy to get a reading on a small target. Then you have to worry about any bits of metal in the field of view reflecting IR from other hot things in the room (like a lightbulb). An inexpensive thermal camera doesn’t have a lot of resolution either. Fun idea, but I’d skip it from a practicality POV

[@harlanstockman5703]

IR cameras for smartphones are pretty inexpensive now-- like $200 (the pixel 8 has one built in?). You get a movie with pretty accurate temperatures (I checked with objects floating in ice water and boiling water)You just have to make sure it has the right usb adapter for your phone. The Seek is pretty good-- I've mapped the temperatures of a supermunter going over a carabiner, for example.

[@dawntreader7079]

the unit i use on my boats engine is extremely precise and accurate. @@marknorton3951

[@marknorton3951]

Yeah, they are good. I have two SEEK Thermal cameras for my iPhone. Also a few standalone thermal camera’s and contactless thermometers at work. I lead an organization of food scientists and process developers. The challenge is going to be resolution and focal range. It’d be a curiosity for a try or two but unlikely to give useful information in this case.

[@SethSchneiderw]

I have a 6mm cord that has a nylon sheath and dyneema core. They recommend a triple fisherman's when joining it together, which surprised me because in my head the grippy nylon is on the outside, so it shouldn't matter. Now I see that a core can just slip right through under the right circumstances. Although it still seems like a double fisherman's would still fail by breaking and not slipping.

[@harlanstockman5703]

I am astounded by how well the dyneema did.

[@SethSchneiderw]

Me too actually. I would like to see more tests to solidify my confidence in double fisherman's in dyneema.

[@harlanstockman5703]

@@SethSchneiderw I was assuming Ryan's Dyneema was 1/4". I just tried 1/8" Amsteel, 2500 lbs average, triple fishermans. No joy, broke at 840 lbs (640 Hz), about 1/3 of the strength

[@richardf9137]

Even though I’m an arborist, I love watching these test!

[@AssafLevyIL]

Same!

[@seanlarson8968]

This is actually super interesting for tying fishing leaders. Braided line is incredibly slippery so joining it to mono line is always a weak point.

[@spud_67]

good to see i can keep using a double and not die.

[@LoveAndClimbing]

I get a slightly larger joy from your videos when you test stuff that is exactly what use (in this case, the double fisherman's in Sterling PowerCord) than your other videos.

[@hummerchine]

That slipping out of the sheath! How interesting!

[@adamfrombefore]

Can you use a Flemish Bend for Sterling PowerCord to make a loop?

[@undaware]

I'd love for you to test a knot we often used for setting up a rappel. It was a double fishermans with a pigtail between them. We used them to make breaking the knot down easier. One line was tied as normal and the other had a single tucked wrap before tieing the other double fishermans. Please, please test.

[@prestonakin6618]

People don't see it bc of the usual camera angle , bit you've got some of the biggest balls in the industry for some of the testing you do to bring us the most legit and up-to-date information . Hats off to ya mate

[@heighRick]

Thanks for all the info, helps a lot!

[@jonathanandrade176]

It was interesting to see that dynema has a use with knots tied in it. Just to see if the knot slips.

[@mowgliadventuresnet303]

Awesome video thank you

[@RickJames-h9n]

I'd love to see this with the bluewater titan chord (dyneema core nylon sheath)

[@ryenschimerman2127]

Agreed, I would also like to see a Triple Fisherman's vs. a Flemish Bend.

[@RickJames-h9n]

@@ryenschimerman2127 The only knot that bluewater says you can tie in it is the triple fishermans. It'd be really cool to see what it does in an 8 on a bight and a bowline.

[@Govanification]

I imagine it would fail similarly to the powercord shown in this video, where the core essentially slipped inside the sheath and into / through the knot. Dyneema is even more slippery than aramid so it might be even worse. You can melt dyneema, however, so I'm not sure if fusing the sheath and core together for like the last 1/2" at the end of the cord would give any strength benefit / resistance to sheath slippage.

[@ryenschimerman2127]

@@RickJames-h9n 100% agree and it's what I do. However, I love the flem in my cordelettes because I can pull them in a pinch if I need the full length. I mean Petzl doesn't recommend the GriGri for rope assent or ledge safety, but it's an accepted usease.

[@Keldor314]

Are well dressed fisherman's knots easier to untie aften having been tensioned? I know it made a difference with figure-8s...

[@moshikom9492]

I have a 25 kn kong frogg leash for my dog which i love and feels very secure. Would love to see kn testing on a genuine kong frogg vs knockoff ones from amozon!

[@TimothyShaw]

What about other bends like the Carrick bend, Zeppelin bend, or Figure 8 bend?

[@bqoutdoors2334]

[@spartin215]

Can you please do double sheet bend with power cord?? Its what I use the most

[@roberthildebrand1780]

Please add a link to the video you recommend watching. Thanks!

[@tjb8841]

If you are supposed to use a triple fisherman’s knot to tie the thin tech cord into a loop, are you actually saving any weight/size compared to thicker nylon cord tied with a double?

[@tylerjbellows]

What about double fisherman's with both ends pointing the same way? I use that knot for rappelling.

[@maxspeed8322]

Isn't climbing equipment designed more for 'shock' loading - as apposed to 'dynamic' loading - that you're testing here? Also what effect on the performance of cordage does the heat generated during your tests have on the strength of said cordage. How do the manufacturers perform these tests (surely they must) and do they publish the data?

[@NatetheAceOfficial]

Some caving gear would be sweet to have in the shop. I don't know what it would take to carry Swaygo or Dirty Dan's but it'd be cool if you did.

[@bandana_girl6507]

I know I've seen different numbers of fisherman's on each end be suggested when tying two different types of line together (usually specifically with fishing line where it allows for a taper for fly fishing, but also I've seen if you're pulling a rope with a smaller line that was easier to get somewhere)

[@johnfrancismacaluso]

i would like to see this type of scrutiny on the Flemish bend

[@bsears693]

Can you show an example of a bad doibel fosherman where the knot coils up then back down instead of down then back up

[@andrewhunter6536]

Dyneema core with nylon sheath rope would be interesting. That’s what I have on some old hexes

[@smau990]

How about hunters bend or using alpine butterfly to join two ends?

[@MarcDonahu]

Always back up with a overhand?

[@oneilljames1]

I am a crab fisherman, heres my two cents on fosherman knots. We only join lines with single fishermans with one hand witdth of tail. If i plan on untying it then I use a tripple. Crab pots weigh 140 lbs empty and I pull them at a little less than 2m per second thru the water column producing quite a lot of drag. The lines also are subjected to cyclic loading from currents and wave action on the bouy. Line is 5/16 polysteel tripple twist with a mbs of around 12kn. I have never seen a single, double, or tripple slip or work itself loose from cyclic loading or from hauling, the knots have to be cut out as they are almost impossible to untie once set. I will continue to use doubles for joing climbing ropes, but habe always suspected singles are super good enough.

[@juper0]

so much like the fig 8, it seems the "backup" or "safety" knot (an overhand on both ends after the fisherman is tied) is completely unnecessary/useless. can't be 100% sure of that from this, but it looks like it would not make a big difference it any at all. if and when you do drop tests with this knot, could you include stopper/backup knots? in the rescue industry, people argue about this and I would like enough backyard science to justify some engineer and steril lab time to convince people that the backup knots are not adding to the equation. super happy about your work and your new store. thank you for the great content!

[@snigwithasword1284]

Im not a climber (yet) and im wondering if there are knots i could screw up and then be saved by stopper knots.

[@becominghumanpodcast]

​@@snigwithasword1284 the chosen knots are redundant and easy to check. You will remember your knots by heart in time.

[@Mike-oz4cv]

In the alps we’ve been using figure 8s without additional knots and European Death Knots (instead of fishermen’s) for decades and I’m not aware of any knot failure.

[@zacharylaschober]

@@snigwithasword1284while I have never seen a climber, once taught, improperly tie a rewoven eight and leave the ground, I have seen a mass of climbers tie not a half of a double fisherman as a "backup" even though this itself would not hold. Worse is this gets used to join cord such as with third hands or to rap off two lines and even as a stopper, and folks have the same tendency to tie the wrong one there as I have seen on quad anchors and prusiks they have had.

[@sikaaaa]

Why not use a butterfly or zeppelin bend? It takes about half as long to tie, and can be much more easily undressed after being put under load.

[@johnhmstr]

I honestly have never used anything less than a triple or quad fisherman's knot... given my upbringing and who i learned knot tying from i am a little bit flabbergasted that there is such thing as a double fisherman's... ha!

[@tomdchi12]

Anyone who doesn’t back up their triple fisherman with a double fisherman’s on both sides is a reckless lunatic, obviously!

[@jaspersonnyoner]

All of these knots are worse and harder to tie than simply tying an alpine butterfly in any of these situations. Change my mind.

[@dunklezwiebel]

If you can't untie the knot, chances are pretty low that it unties itself.

[@Frostbiker]

There is a long video in this very channel that shows how the double fisherman's and the figure 8 are slightly stronger than the Alpine butterfly. Either of those knots is super good enough, but claiming that the Alpine butterfly is stronger is simply incorrect.
