The Grivel Spring Leash lets you take advantage of leashless tools without the risk of dropping one off a steep ice route or half way up an alpine climb. Available as a single leash for mountaineering or a double for the steep stuff, this leash contracts to keep from tangling an extends to your full reach. Just girth hitch this leash to your belay loop, clip the carabiners to the hold in your tools handle, and get after it.
