The DoohicKey QuicKey and SkullKey Tools are simple, key-shaped tools that attach to your key ring, so they're always at hand when you need them. This product's clever design incorporates each of the following functions: a file, a #2 flat-head screwdriver, a scoring point (great as a box cutter and for easily opening clamshell packages), a serrated edge (to saw through twine and clothing tags) and, finally, of course, a bottle opener (because you always want a bottle opener). Made of durable stainless steel, the DoohicKey QuicKey and SkullKey Tools are travel and airport friendly and, because of their endless uses, endlessly useful.
