In addition to a carabiner clip that easily attaches the tool to your pack, belt loop, or key ring, there's also a built-in cord/seatbelt cutter, a bottle opener, three hex wrenches (1/8, 1/4, & 3/16 sizes), and a key ring hole. In addition to all its onboard tools, the carabiner features heavy jimping where it counts-so there's always solid traction when you're using the tools.
