The concept of having all your essential tools right there in your pocket is nice. The idea of being able to actually survive in the wild with them is even nicer.
Sure, amongst the 19 tools on the new Leatherman Signal ($100) are the generally handy knives, wrenches, screwdrivers, bit drivers, pliers, can and bottle openers you'd expect.
But it also offers the kind that can save your can in a pinch, such as an awl, saw, combination fire starter and whistle, and removable diamond-coated blade sharpener.
Featuring a locking mechanism and some one-handed operation, it's made from high-carbon stainless steel and coated with a carbon-based substance—you can never have too much carbon—to make for one super-tough, scratch- and corrosion-resistant tool.
