The Leatherman Wave is a classic multi-tool.
Simple to use, loaded with 17 tools, and dependable, I carry my Leatherman around everywhere. I have one in my car, in my backpack, and one for the house.
The tools on the Leatherman are designed for efficiency. Every tool is strong enough to do the job intended and light enough to carry around. The Leatherman Wave is the definition of multipurpose. Designed to save weight, maybe even your life.
