A decade ago I found this nifty little kit shovel. The metal handle was pretty solid and as ergonomic as you could expect, with a rubber grip and all, but the working end had a yoke that allowed you to change out the shovel for a pick, or a saw, or a hatchet. It all packed into a cordura bag, and snuggled nicely into a BOB. Considering the multi-task nature of the package, I found it quite functional for it's scale. Things such as these are always a compromise from having a tool dedicated to a specific task, but this was perhaps one of the more functional compromises I've seen in a while. Even a Leatherman Wave is a compromise, if you think about it.
