Crank Brothers Multi-10 Tool
This Crank Brothers multi-tool has a design that's simple and functional. All the tools you will need out on the trail and that fits perfect in any hydration pack.
This is the perfect multi-tool. It's light, strong and compact. The only problem with this is it does not like water. There was a rain storm that got my pack wet and I forgot it was in there. Several days later when I got it out rust has started to set in. A minor inconvenience, as this doesn't affect the functionality in anyway but still not cool. Other than that I would give it a 5.
