Molly Ohm on Instagram: "When’s the last time you checked the sharpness of your rappel device? PSA for climbers out there that do a lot of rappelling, ATCs / tube devices can get really sharp from ropes running through them! If they’re sharp they can start to abrade your rope sheath (ever seen colorful fuzzies all over your device at the bottom?) and could use a replacement. Also might be time to replace my carabiner 😅"
