The Surge is one of Leatherman's two largest multi-tools; a real powerhouse, built with their two largest pliers, longest multi-tool blades, and easy-to-use locks. A unique blade exchanger, replaceable premium wire cutters, and four outside-opening blades give you quick access to the tools you use most. The 21-in-1 Surge multi-tool is built for tough jobs and the hands that do them.
