We're used to multi-tools that fit in your pocket, so seeing the Crovel ($85) for the first time was a bit of a shock. Named for its mashup of a shovel and crowbar, the Crovel also serves as a saw, axe, hammer, bottle opener, and more, letting you pack lighter while preserving maximum utility. Just don't let it fall into the wrong hands — if an axe murderer is deadly with his namesake weapon, imagine the damage he could inflict with this thing.
