Blew out my climbing line's core on a red oak in Tacoma, and the outer sheath looked fine until it didn't
Was chunking down a spar on Friday when my 3 year old 16 strand let go about 20 feet up, no warning, just a soft pop and a sudden drop that my flip line caught. Now I'm checking my ropes with a fingernail every single climb, so what's your go to way to spot core damage before it turns into a fall?
