Samson AmSteel-Blue is a 12-strand single braid rope woven from SK78 Dyneema. The addition of a Samthane urethane coating adds up to 30 per cent to the abrasion resistance of the rope.
It is ideally suited for canyon environments as it floats on water, is naturally resistant to degradation caused by water or UV exposure, has exceptional abrasion and cut resistance, and is lightweight and compact.
We stock it in high-visibility yellow, making it easier to deploy and manage in dark canyon environments.
The combination of a tighter weave than many cheaper Dyneema braided ropes, along with the Samthene coating, means it is much stronger and longer-lasting than the competition.

Larger diametres of Samson AmSteel-Blue rope are used extensively in maritime, mining, and defence industries, where the exceptional strength and abrasion resistance have made it an ideal replacement for traditional steel cables.
Samson manufactures the rope using Dyneema SK78 (an Ultra High Molecular Weight Polyethylene, UHMWPE). Dyneema is one of a number of advanced fibres now available for rope manufacture, however it retains the best strength to weight ratio.
Be aware that Dyneema comes in six grades, with differing strength, stretch, and abrasion resistance. The use of SK78, combined with a tighter weave and Samthane coating, means Amsteel-Blue has up to 30 per cent higher breaking strength, and much better abrasion resistance, than many similar products.
Dyneema is produced by drawing fibres from a gel, producing extremely long molecular chains. It is up to 15 times stronger than steel on a weight for weight basis. Because this exceptional strength is achieved with much less material than other rope products, Dyneema also delivers the lowest carbon footprint per unit of strength.
Note: Thin 3mm cord can bite into your hand during a hard pull, so consider wearing gloves or attaching a carabiner to the pull cord with an appropriate hitch when undertaking challenging pull downs. The exceptionally low friction of Dyneema fibres can cause some types of knots to slip. The low melting point of Dyneema makes it unsuitable to abseil on directly, even in an emergency.
