Multiple Uses for Ice Climbing
"I use these for all sorts of things in my personal climbing, film rigging work, and guiding. They make a great backup for rappelling, work well with a pulley for crevasse rescue or industrial tension applications that need to be high strength and non-damaging to the load lines, just great tools for all sorts of situations. I had one on my harness when I climbed Niagara, as I always do, it’s a sort of ‘get out of jail’ card for a lot of situations. Plus they weigh nothing and last a really long time."
