The Leatherman Signal packs 19 tools into a 4.5-inch frame built for the outdoors. Its standout pieces are a ferro rod fire starter, a built-in hammer and an emergency whistle, which most compact multi-tools lack. The 420HC combo blade, bit driver and removable pocket clip cover everyday repair and camp chores. It suits hikers, campers and bushcrafters more than office or bike riders, who get lighter, cheaper tools without the fire starter. Owners rate it well overall, though some find it heavy and bulky for pocket carry and say the ferro rod is small for serious fire-making.

Buyers rate the Signal highly as an outdoor multi-tool, praising the fire starter, whistle and hammer as genuinely useful additions. Criticism centers on its weight and on the ferro rod's small size and limited life.
The Leatherman Signal is a compact multi-tool that combines 19 tools in a 4.5 inch body. It is the first compact multi-tool with a built-in ferro rod, hammer and emergency whistle.
The 420HC combo knife blade has a straight edge for slicing and a serrated edge for tough materials. The steel is easy to sharpen, and the tool has a built-in knife sharpener for touch-ups. A customizable bit driver tightens gear, and the built-in hammer can anchor tent stakes.
A locking mechanism and a removable pocket clip let you carry it in a pocket or pack. The stainless steel and black versions have a DLC coating. The coyote tan, aqua, crimson, grey and cobalt versions have a Cerakote finish.
