CrunchGear: Whether you just need a knife and screwdriver or a whole suite of doodads, there’s a multi-tool out there for you. But there are a lot to choose from, so we contacted some of the top manufacturers and had them send us their best gear. Gerber, Buck, SOG, Leatherman, and CRKT all sent us their top-of-the-line tools so we could give them a fair and honest comparison.
