For something so small, the Gerber Artifact has quite a few uses. The tiny pocket tool (1 1/2 ounces) contains a replaceable razor blade, a mini pry bar, and a bottle opener. There is also a Phillips screwdriver and two sizes of slot-head drivers. The tool has a lanyard for attaching to a keychain. It might not be a primary tool, but it could certainly help out in a crawl space. Price: $12 / COO: China /
