Crankbrothers' shop quality Y-tool uses a number of magnetic and snap-fit latches to keep the pointy bits protected from your body, and the contents of your pack or pockets. A magnetic socket and Allen tip allow the user to one-hand either tool, or lock in the chain tool or hex bits, wich are stowed in the triangular-shaped plastic case. Bits include all the Allens and Torx sizes popularly used, a valved Co2 inflation head, two tri-wrenches, and a chain breaker. Yeah, it's cool.
