In 2001, I was climbing a big wall in Zion National Park with two of our
former guides. Prodigal
Son is an "easy" aid route that ascends the Northeast Face of Angels
Landing. As it was late in the Fall and it was getting dark early,
we elected to fix the first aid pitches and then complete the ascent to
the top on the following day.
On the second day of the climb we made our way to the base of the wall
in the dark. The approach was not pleasant. We had to forge the
freezing Virgin River at 5am. And then we each began to jug the fixed
lines with mechanical ascenders.
For some reason, I was the last person to climb the ropes. As I climbed
up the second rope, dawn was breaking and it was much easier to see.
And what I saw was terrifying...
Near the top of the second line, there was a hint of white peaking
through a seriously damaged rope sheath. The line was core shot. And I
was below the damage!
I quickly climbed through the damaged section of rope and clipped into
the anchor. Safe.
Three of us climbed up that rope on jumars. The bouncing motion of our
movement and the dynamic nature of the rope caused it to repeatedly rub
on the sandstone, allowing the coarse stone to saw through the sheath.
Ultimately, we finished the wall. But that particular incident has
stuck with me for years. Indeed, it has made me extremely cautious
while aid climbing and constantly concerned about sharp edges while free
climbing.
Recently the rope manufacturer Beal,
revealed a new technology that they are calling Uni Core. The concept
is that the core and the sheath are integrated and that it will be much
harder for rope damage to have a catastrophic effect.
The following video is pretty convincing:
Certainly the catastrophic effect of the knife on the rope would have
been mitigated by knots in the rope. Aid climbers on jumars are taught
to knot the rope as they climb for just such a possibility. And indeed,
in my situation back in Zion, had the sheath completely come apart, I
would have been shaken up, but okay. I had placed knots in the rope.
I haven't used one of these ropes yet and have no idea how well they
handle. But as this is a major jump in rope safety, I thought it
important to discuss it here.

The YMCA here in Bellingham has them on the rock wall I think they just updated them. They are awesome! They have a different more solid feel in your hands but not stiff at all, also they lower super quick, all around they just have a more dense feel.
