We don’t need to explain to any of you how functionally awesome each and every Leatherman multi-tool is, but their new Signal multi-tool is still worth talking about because of all the new additions Leatherman has made. The traditional features that make other Leathermans great—pliers, blades, saw, pocket clip, screwdrivers, can opener, etc.—are all here, but Signal also has a ferrocerium fire starter, emergency whistle, hammer and replaceable wire cutters. If you’re look for a new tool you can carry into the wilderness—as opposed to upgrading your existing Leatherman by carrying a fire starter and whistle—check out the Leatherman Signal.
