Most all-in-one tools are handy around the house, but not so much when you're out in the wild. The Leatherman Signal Multi-Tool excels in both scenarios. It has a cadre of survival-focused tools — including a 2.7" combination knife, saw, awl, safety whistle, a diamond-coated sharpener, and fire-starting Ferro rod — that can help you out on the trail should the need arise. Meanwhile, it has needlenose and regular pliers, wire cutters and stripper, a flat end for hammering, can and bottle openers, 1/4" and 3/16" box wrenches, and 1/4" hex and regular bit drivers for more common uses, finished off with a carabiner for clipping onto a belt or bag.
