Crank Brothers has a reputation for well thought-out, high-quality tools, and the Multi 19 demonstrates why.
It's a lesson in how to pack the maximum number of functions efficiently into one compact space, yet maintain ease of use for all of them. It's on the expensive side, but worth the extra stretch if you want the reassurance of carrying more than the minimum. It also comes in a smooth pack that slides easily into a pocket and means you won't get stuck with spiky bits when you crash. Style aficionados may want it for that alone - we just want it.
