Any ropes with no sheath slip when damaged?

[James905]

I have a pal who had the sheath fail while ascending a static rope on a frogj setup (croll + hand jammer). As said he came to a slow and gentle stop as the sheath bunched up beneath him. Then had to go up the exposed core strands...
Obviously only works if there's a knot in the end though... personally I'd rather a rope with bonded core and sheath.

Shame there's not some rope makers in on this! Glad your friend was OK and had a knot in the end!

What caused the failure?

 

Glad he was ok, must have been scary to say the least!

As said, some static lines do have a bonded core and sheath. Courant certainly do one, as do some others (I believe someone mentioned Beal earlier)

 

As for my pal, he was caving, and a victim of poor rigging I believe. Rope had some slight rub on rock which caused the failure.
