When i'm tradding, I keep two of these in the zipper pouch on the side of my chalk bag with some rap rings and a blade. Makes a nice little "get out of trouble" kit. Use them with caution though, if you let it slide on your rope rather than pressing it in with your thumb, as the directions show, it'll shred it. And the hard steel is pretty rough on some biners. Had to use them once so far to get my second out of some trouble. Direct belay with a reverso + 1 tibloc = Z pulley reduction. If you're creative, you can ascend with just one and a reverso/ATC-G too. Good to have, but really hope to never use.
