I read somewhere that Kevlar breaks down after a awhile. That's why bullet- proof vests are replaced every few years. Not sure if same principle would apply to cordage, though. Just a thought.
Thanks for the shout out. I think the main advantage of the Kevlar cord is that you can store 3x the cordage in the same space without sacrificing cord strength. Personally, I carry paracord, small reels of kevlar and technora and some 250lb tar bank line in my Get Home Bag and in my vehicle.
Which is better in high heat situations? Like if I had to use 50 feet of 2.5mm cordage (para or kevlar) to rappel out of a burning building in an absolute emergency, what would be the best choice that will hold up against heat?🤔
Kevlar was used in bow strings and didn't last very long, it had the bad habit of sudden failure. Kevlar degrades with age... degrades in contact with human oils and sweat. Its now only used in high end bowstrings and a 50/50 mix with other polymers so when the Kevlar fails the string doesn't break and destroy the bow. Military grade paracord IS UV resistant... I have paracord thats been outside in full Australian sun for 2 years and is still fine.

I guess everyone has their favorites, use the one that YOU like best. I've used para cord and it worked well for my purposes. I like Dyneema also, it's a lot stronger and floats, but much more expensive and I've only been able to buy it on-line.
In my hammock camping gear, we like to use hollow braid dyneema cords. Samson is a major maker of it. Their 1.75mm and 2.2mm cords (LashIt/ZingIt) with ratings of 450# and 650# are used for many applications. It is easy to splice loops into. IT has a slippery coating so it doesn't hold knots as well. It waterproof, floats and is quite abrasion resistant and doesn't tangle easily. It is also quite light. Many arborists use this line as a throw line. There is also another dyneema cord know as Dynaglide which is 1.8mm with a breaking strength of 1000# and has all the same properties of the other cords above

I found some of this cord in the edges of an expensive tarp that my husband had for his hay stack. The tarp was falling apart so I took the cord out and saved it. I'n pretty sure it is the same stuff
Also, 550 paracord has seven paired strand in it's core. Each strand is a twisted pair. You can break the core down to fishing line, stitching material, floss, netting, etc. Much more versatile than the Kevlar.
an good trick is to wrap nylon thread (with a needle) around the tip- sinew and dental flosswork too and run the needle in and out of the wrap to fuse the thread keeping it from slipping prevents fraying father, then trim the rest of the fibers as close to the edge as you can without disturbing the fuse I leave about a centimeter left. our you can dip the ends in plastic, wax glue. for added protection you can do both warping then dipping the tip, or just melting the nylon thread after you wrapped around the rope/cord. But the simple knot with a Buzz cut works in a pinch.
I feel like this would be good to use for boot laces on a motorcycle boot due to its abrasion resistance. That way your laces don't disintegrate as you're sliding and your boot will be less likely to go flying off which would leave your foot exposed to the pavement for the rest of the slide.
Regarding the fraying ends and maybe how to stop that(I haven't tested it myself yet) is to pull a little extra nylon past the sheath before it frays too much, melt the nylon and then kinda mold the melted part over the sheath. Again, never tested this out, getting Kevlar cord soon though and will then
Thank you sir, please remember that if you are in an urban area fires will occur on large scale vs rural areas in a crisis, angry people will start fires to increase confusion. Which has happened in Detroit and will continue to happen in Detroit. Water mains will break on a larger scale than now, which in urban northeast USA almost a weekly event. Purchase items of highest quality to assist in a crisis priceless. Excellent video, please teach your bloggers the bowline knot essential for surveil wether urban, suburban or rural. The clove hitch good for individuals for basic tying. God Bless
jonathan bosco There are loads of visual knot tutorials on youtube at peoples disposal. I agree that fire will be a major issue, good to have a couple of extinguishers on hand at the very least.
Braided, coated kevlar is available as speargun line at about 400 lbs rated strength. The low-stretch is really one of the key features of that cord. Kevlar will dull a blade more than many other types of cordage. But, unless you are cutting a LOT of it, it shouldn't be an issue. Kevlar is a cousin to nomex that is used in the flame resistant suits As for the ends. tape or glue tend to work to protect the ends of kevlar from fraying. Overall, I think that your conclusions is generally correct. Aramid fibers are better used in climbing or lifting situations where the stretch isn't as critical. If you want really crazy strength in a relatively small rope look at synthetic cord for towing. 7000 lbs in a 1/4" cord.

I use tons and tons of paracord I'll have around 20,000 feet constantly. I'm the product developer of NavyHammocks.. Creator and patent holder of the Toggle Rope. 550 commercial grade and military grade paracord is uv resistant, rot resistant, mildew resistant. It has. 15% stretch and will not stretch further than that. I've used as a bow string and have had it on a recurve for over a year now. I was thinking about making new gear with Kevlar as an option to add our paracord gear, specifically for the less stretch and better abrasion resistance
+Trevor McCurdy I think that would be VERY cool, let me know if you wanted me to test out some gear on the channel BTW. Kevlar is fairly expensive so that would likely be a major barrier.
But gutting also removes most of the strength of the cord. The whole idea of the kernmantle rope is that the interior cords carry the load while the woven outer protects against abrasion etc. Gutting it reduces the strength to basically nothing (ok, somewhere around 200 lb of static load if you're being pedantic).
Haven't seen the kevlar cord yet, but as thread for sewing the kevlar thread seems real superior. I get leather work gloves sewn with kevlar and they are darn near indestructible. The very same gloves sewn with cotton last no time at all before they are falling apart at the seams. Well worth the extra $10/dozen pairs for the kevlar sewn variety.
Check out Amsteel, at 1/8" you have 2,500lbs. This stuff is used for marine applications, which makes it particularly brilliant for survival situations. (UV, abrasion, water/salt] www.reddenmarine.com/index.php/amsteel-blue
true mil-spec paracord IS UV and Abrasion resistant. (there are videos of it being used to saw through wood) this stuff is maybe a substitute for tarred bank line (other than cost...you can get almost 500 feet / 150m of #36 (which is around 350-400lb test I believe) for $15 USD. For most survival applications, that is more than enough strength.
Thank you for this. I was Amazoning paracord vs. kevlar cord and found your great video. 100' of black paracord on the way. What is the braid pattern used in your lanyard? It's really nice.
nice produc t but too expensive for me in Australia, $114 (including post) for 250' for Technora 950 Kevlar cord, where as 550 paracord costs me around $10.28 for 300'
+Orion The price will be coming down soon, I am going to be doing another video on synthetic cordage options soon. That price seems way too high even for kevlar cord so you may want to research other sellers.
the problem for me is postage, Ebay has 1 seller (from the UK) and cost of the cord is $37.16 but the postage is $67.61. If this cordage becomes available retail here in Australia I will definitely buy it, as I said it seems like a fantastic product.
+Canadian Prepper have you tried the various Bank Lines? Paracord tends to be a little too thick sometimes for some applications, where as bankline (I have the #36) seems to suit these applications. The only thing I have found as a negative of bankline is the tar coating is sticky and smelly.
I bought some of this technora 950 cord some years ago, seduced by the super strength thing. It's next to useless in the outdoors. It taught me one very important thing, if you want your cordage to keep tension on something (which you almost always do), then it needs to have at least _some_ stretch. This technora cord has none. Zip, nada, nothing. It's completely dead. You can put 200lbs of tension into it trying to get a taught ridge and as soon as you back off even a millionth of an inch (like trying to lock the tension off with a hitch or knot), the line goes slack. You cannot put tension in this stuff - _at all_ - even with a truckers hitch. Paracord is like a rubber band by comparison. An improvised bow string is the only useful thing I can think of doing with it - or maybe a hammock suspension line. Unless you have a specific need for cordage with zero stretch, this stuff should be avoided.
Nice comparison. You should also check out the other synthetic fibers, which can be even stronger than aramids like Kevlar(TM): Dyneema(TM)/Spectra(TM) which are UHMWPE (polyethylene) Vectran(TM) which is a liquid-crystal polymer Zylon(TM) which is polyoxazole They all have their pros/cons. I also wanted to say that it might be great to find a fiber even stronger than venerable 550# paracord, but sometimes I question the true real-world usefulness of a 900#+ fiber that's so thin in diameter. Sure it's great that they have these ridiculously strong synth fibers, but when would I ever need a 1/16'' diameter cordage to hold 900#? The 550 stuff still has many great advantages, due to the sheathed inner core construction, and the O.D. of it seems to be right in the sweet-spot for many uses.
Paracord all the way for me. Its easier to work with, more convenient, and is much more multi functional. Imo, 550 lbs break strength is more than enough for any wilderness scenario and most urban uses. If you need the strength, it can easily be doubled or braided. I think the only other cordage thats a competitor to paracord is bankline, especially for the price, and the size, with the amount of length you get. Again, I see paracord more multi functional than any other cordage on the market.
Josh Myers I believe it! I have even used paracord to hold my bumper, my hood down, and to kept my headlight assembly from falling out after I nailed a deer with my jeep. I would rather have paracord than rope or bungees I keep in my Jeep.
LEO1WOLF it's good shit. I have 200 feet in the room right now and all my long guns have paracord slings. it may well save someone's life. particularly around water
Canadian Prepper I have access to about 4,500ft of kevlar thread (reinforcement for fiber optic medis).. I'm gonna weave cordage and re-stuff 550 with it. should be good use for stuff I was going to throw out anyhow.
Nothing feels like good broken in paracord. It's overkill most of the time as far as strength goes, but I've tried lighter cords and they are too thin to manipulate knots. Para still wins even though I'd like a light version. The kevlar is interesting though.
NewHampshire Bound I agree with you in most respects, paracord is still the better option, especially this new firecord, that said I still like having some kevlar around for its abrasion and heat resistance qualities.
Burning a Teflon-coated cord is actually pretty sketchy. If the Teflon gets hot enough it will decompose into fluorine compounds. A typical lighter flame is plenty hot enough to decompose Teflon.
thinking back to my paradangling days; I seem to remember Kevlar becomes significantly weaker if knotted - I have a feeling it used to be sewn & bonded into rigging points if memory serves me right? just my 2 cents worth :o)
that Kevlar isn't a great material for bush craft / prepping. Great if you want to impress people with your state of the art cord; but not going to last too long as you start using it as cordage.
3000 lb paracord planet paramax 5/16" paracord is the strongest paracord made period.Nobody has ever made a video on it probably because almost every seller has listed it as 1200 lb paracord including Amazon, Walmart and even Paracord Planet has a page listing it as 1200.
Which is better in high heat situations? Like if I had to use 50 feet of 2.5mm cordage (paracord, paramax, dynaglide dyneema, amsteel or kevlar) to rappel out of a burning building in an absolute emergency, what would be the best choice that will hold up against heat?🤔
Good comparison, FYI although my experience is limited others have shown that on a 40lb or less traditional bow 550 paracord strings work just fine. Maybe dip the fresh cut ends of the kevlar cord in some sort of glue on pre cut lengths?
Yeah, I was thinking a similar thing for the kevlar ends. Due to the fact you can't melt it, but my head was more going to bee's wax. More because I have loads of it atm haha! I've got alot of it atm, because I'm making a great new homemade fire tinder. I believe that nobody has done the concoction that I'm putting together, not that I've seen anyway. May be starting my own channel soon, so I will post what I do in it 😉
Loved the video. Nice intro to me about the kevlar. I noticed the 550 cord you used is stripped. Is this intentional. I learned of paracord from my time in the army. Always we used the filled with all the fibers inside intact. Just curious
Billy Medlin Stripped? As in all the fibers removed? It may have been for this vid but if it wasnt intentional, probably just got in the way at the time or something!
*PARACORD IS BETTER* Paracord can be used like glue. Kevlar cannot. _(^Patching your ripped tarp. Covering small wounds. Repair water jug. Repair gas canister. Near endless...)_ Paracord makes better handle grip. Paracord holds it's knots better. Paracord can hold everything kevlar can, you just need to double it up on the ridiculously stupid heavy tasks...
i have a lot of 550, but do i need that? i am 5'10" and under 180lbs why do i need anything stronger? i use 550 on my neck keys and accessary lanyard. i bought micro cord from atwood rope and a little thick nano. micro is 100lb. test. i guess i just don't feel the need for stronger than 550. maybe there are applications i have not thought of, but for me this stuff is just rope or line.
There is many places selliing knock off so called real paracord. Not just on ebay. On Amazon too. It is also 7 strand and posted as 550. Do the RU-vid paracord fake vs real test. I would say pay the extra if you want piece of mind for parachuting. Though for anything else why waste the money.
why does UV matter? i say as long as it works who cares! really i don't see fire resistance necessary, since i don't live in a hot climate! anther plus to paracord you forgot was it wont rot or mildew.
Goddess1Princess Hi there, thanks for commenting. I don't think kevlar will rot or mildew either, indeed a lot of the benefits of kevlar over paracord are not really worth the price gap just yet. I do like the fact that paracord is easily seperated into its component strands. UV would only matter if you left something tied outside for a long period of time, the heat resistance would be an added bonus, apparently Kevlar can also be used as a saw due to its heat resistance. I agree overall though paracord may be more versatile for most peoples needs.
but that is not what he said i went with exactly what he said and offered simple math im not a mind reader so if he meant something then HE should have said so in a post i don't think your qualified to say what he thought are you a mind reader i thought not
