Standard keychains have one function: keeping your keys together. A-Tech's has eight. In addition to a metal rope-style ring with a screw lock closure, it has a circular chrome-vanadium steel attachment that holds six different bits, has an integrated driver, and on the other side, packs a flip-out box cutter blade. It's also TSA compliant for travel and has a handsome black finish.
