One of the blogs we occasionally follow is The Mountain World. A recent post of theirs told the story of some rope testing results.

The story should serve as a reminder to all of us who use ropes for climbing (I have an old one I use only for winching down trees, so it doesn’t count!).
The message is: ropes wear out and need to be retired, probably more often than is actual practice.
It’s a short story and interesting reading. See if your ropes qualify to be withdrawn from active duty.
