Who the heck is making Amsteel tethers and Amsteel prussic combos and selling them on FB???

I did have an interesting thought about dyneema and hard bends. Bowstrings are made of dyneema and have very severe angles sometimes around cam post and they seem to hold up fine

I suspect it's a rope/cord specific thing. Also bowstrings (at least on my bow) don't have severe angles relative to their diameter other thn maybe the nock point that's only taking say 35 pounds of load even at a 70 lb draw.

something to consider here.. every where it comes in contact with anything, it'll be served, protecting the fibers..
 
Awesome thread here. Thank you to the guys who contributed to this one. Just finished reading all 122 posts and it has definitely had an impact on my first ever tether and LB purchase. Being brand new to any climbing hobbies, this opened my eyes to hazards that I didn’t realize were out there. I still haven’t made decisions on what exactly I want to run, but I now know some of the questions to ask and research to do before buying. Man I’m grateful for this site.

Same here!

If that is a question you have, you should ask the saddle manufacturer and the rope manufacturer, and do your homework. Why aren't arborists and professionally certified AMGA and IMG's using Amsteel for these purposes and applications? Believe me, it's not cause they missed the boat...

I am going to start this with all things are at your own discretion. I am not pro amsteel for tethers but that’s because of opinion not because of facts….
Arborist aren’t using them because they constantly put forces beyond normal load capacities on their equipment. Arborist do not just sit in the harnesses like hunters do. They swing back and forth to fell branches, hang nearly upside down in their harnesses to crawl out and rig branches. They lift and drop heavy branches. They hang chainsaws and other tools from their saddle. They wear helmets safety glasses long sleeves and chaps while working. And they do all these activities for 8-12 hours a day for 5-6 days a week. That’s a lot more than the average 4 hour sits on the weekends most hunters partake in…. For the longest time arborist saddles didn’t even have adjustable length bridges. They were fixed.
You are correct in that amsteel has a low melting point. This is well documented. Studies have also been done showing that amsteel rarely reaches those temps when used in a hitch because of its coefficient factor and that it is also very slick. So it dissipates heat faster than nylon or polyester. ALL ropes are subject to the rules of bend radius (technora more than most) yet lots of people use oplux. Polyester is subject to bend radius degradation. This is why knots reduce a ropes strength. Amsteel is more abrasion resistant than nylon or polyester although they have outer cores for protection. I am not saying you are wrong. Personally I don’t use amsteel for a tether or linesman rope, nor do I use oplux. But I don’t think it’s totally unsafe because unless you are trying to rappel on amsteel, you aren’t sliding it around to create friction that will degrade the rope. I mean I’m not personally going to carry a chainsaw hunting. Nor will I wear a helmet, chaps and carry 200’ of 5/8” rigging rope with me. If you wanna use arborist standards for safety then none of us can use a tether smaller than 11mm or a prusik smaller than 8mm. Not arguing with your outlook on safety, just offering some facts that might have you look at it differently.

Yes, but Mountaineers and professional climbers are weight weenies...I mean I know people who weigh particular carabiners for climbs and build their rack to a certain weight in a very calculated manner. Amsteel is not anywhere in their kit...no would it be accepted as so.

A dyneema sling that is often used by most climbers for tie offs-dyneema is amsteel. Wait this thread popped up today and I just realized this post was from almost a year ago. Here I am beating a dead horse. Sorry man didn’t realize this was so old- why did it pop up today?

No worries :). Yes it is similar, but a different configuration and weave. Dyneema and spectra slings used in climbing are tubular configuration, TESTED. And SEWN. No knots, no splicing....

They are not using dyneema ROPE.

They're also designed for specific static applications...
 
So did every one agree on an answer? Or is it still a debate. I got the answer that amsteel is okay in a non moving situation as long as it's not over bent. Not meant to repell down. (Moving component). If inspected before use is good in a static load. But like everything should be inspected before use and ensured in good working order. Or did I miss the boat?

My suggestion is to read the Samson manual on it and make your own decision. They have never tested, or recommended it for life support....
 
i never thought of any part of my saddle as life support.not a fall arest system or fall restraint system eather.just a seat i cant fall out of.i think of it as somthing i sit on in a tree.when i climb trees and sit on the branches i dont think of them as life suport.just good enough to hold me up.my saddle is for siting on not for falling swinging or shockloading.i agrea with what you said and ive never even used amsteel.but the reality is its just a seat stitched with thread

I agree with everything you said. Key words being that amsteel is “good in a static load”. I personally do not consider my tether a static load ONLY. There is still the potential for a fall and shock loading… even though I do my very best to avoid slack in my tether.

My first line of safety is being disciplined in how I manage my tether. But I prefer having my equipment capable of withstanding my mistakes (because I am human and I certainly make some). It ultimately comes down to your personal risk tolerance.

Yup, just a seat with Specific thread, in a certain pattern, with certain number of stitches per inch per lb of strength....made of certain materials, tested to failure...

Anything supporting a life hanging somewhere that could kill or severely mame you is life support...

I found this interesting, not sure it’s not for life support but they have amsteel listed on their site advertised as safety lifeline ??? That’s kind of condescending

I suggest you read the Samson manual. All the information anyone needs to make an informed decision is there..including safety factor calculation and such...

That is an awfully casual attitude about some awfully serious consequences. I really hope nothing ever happens that changes your mind about safety too late... I don’t believe anyone here will be able to, so I just hope you stay lucky my friend.

i make my own gear .none store bought from the ground up.even my kids climb trees,in flip flops .no safety gear. do kids not climb trees in other states no tree forts or rope swings.ive been climbing trees since i could walk no linemens belt rated to what ever.perfectly responcible for my own life as a child.same life suport in a tree i use in a fight my hands and feet.my ladder stand doesnt say life suport on it.just 300 lbs.concerned sometimes but not scared about how high my kids will climb a tree but saddle hunting was invented by people who wernt scared to do what others think is so crazy.and yet here we are.some are fine where they are at .im not scared to push the bar until we go from light weight to ultra light.if i was scared id get a ground blind .only makes since.now im gunna buy amsteel.love you man but it just sounds like the panic police tryin to poo poo someones party.makes me want to party .whatcha scared about

Sorry man, I didn’t realize I was talking to a bonafied hillbilly bad@$$ who can climb trees without a fort AND fight with his bare hands. That changes everything. Obviously you’re right - if you can do those 2 things without being scared, then it makes sense you will never fall out of a tree and snap a piece of amsteel with your body weight. That is unless you wanted to, because I’m sure if needed you could break amsteel with your bare hands too.
