amsteel blue

I am not familiar with this product at all, but I see you guys talking about it alot. With the strenght of this stuff....could you not just make a tether out of it instead of the static line?

It's so slick that a prussic has trouble gripping it and I doubt it will work with a ropeman. Also it isn't very wear resistant so moving on the tree will show signs of wear. You would need a sheath on it like they use when they use amsteal for winch rope. That what got red looking at that Samson rope. It has a tough sheath.

Strength wise - yes.

However, it's not very abrasion resistant and, unlike climbing rope, it isn't made to absorb a big fall.

Samson Ultra-tech is probably a better tether option. It has the amsteel blue core, with a tougher exterior sheath.

So its flexible enough to make my own tether and still work in my ropeman 1?

Yes. @redsquirrel is using it for his tether.

Not to nit pick, but ultra-tech is not amsteel with a shealth. Amsteel 2 is amsteel with a sheath. ultra-tech has technora core, amsteel is dyneema. I tried to google the differences, this seemed like the easiest read.

There are multiple different types of synthetic winch lines available today, many of them are made from Dyneema fibers, while others are made from, Technora®, Vectran®, Spectra®, or Kevlar®. Each fiber has benefits and disadvantages and can be chosen depending on your unique application.


Technora® and Vectran® fibers are very heat resistant but are susceptible to bend fatigue. This is not ideal for off-road winching since winch lines are repeatedly bent around radiuses, such as a fairleads or snatch blocks.


Spectra is similar to Dyneema fiber, but is not as strong or as durable. Because of its strength and durability, Dyneema is the premier synthetic fiber for winching applications. There are multiple different types of Dyneema fiber, with the two most popular being Sk75 and Sk60, Sk75 being the stronger of the two.


Regardless of the fiber, all winch lines are braided in a 12 strand construction. Each strand is composed of many fibers and 12 strands are woven together to form the rope.


All Master Pull winch lines are made with Dyneema Sk75 fiber ropes for superior strength and quality. We offer three different versions of winch lines of varying performance.

I have an inquiry in with samson engineers on using amsteel as a tether. He felt chain would be a better option. I sent him another pic and explanation on my intended use, waiting to hear back from him.

Lucky I found someone who sells it locally...the chance is that if they have scrap laying around they will sell it...if not they sell it by the roll....:-(

So with amsteel 2 how small could I go in diameter and still be safe?

So with amsteel 2 how small could I go in diameter and still be safe?

Lots of info being thrown around in here so let's slow it down for a minute.

A quick recap:
Amsteel: strong and very light. No outer sheath and not very resistant to wear. Can not use with a mechanical ascender such as a ropeman. Some are using it for their bridge. A few of have looked into creating a tether with it, but since you can't use a ropeman and its not very resistant to wear, no one is using it.
Amsteel 2: this is amsteel with a sheath. Adding a sheath makes it more resistant to wear, but in order to use it with an ascender you need to go up to 11mm (for the ropeman per their specs). The weight of amsteel 2 is very similar to yale bandit and the higher strength rating is way, way overkill for our applications.
Samson ultra tech: High strength, low stretch with an outer sheath.

This is why I am using the samson ultra tech. I am using it in the 9mm version which is nice and light. I am using a kong duck with it, the duck is rated to 8mm rope Remember the ropeman1 is only rated to 10mm rope. @MCDM picked up some ultra tech in 11mm.

There is a price for safety. I paid around $3.50 per foot for 11mm. Would i have been fine with buying a different rope grab and going a cheaper route... probably!! But I knew what I wanted and instead of cancelling orders I bit the bullet. Things to consider i guess but im happy knowing I spent some money to be safe after doing the research and input from several saddlers.
