Utili-Key 6-in-1 Tool
If your mini swiss army knife isn't cutting it for you anymore, here's a cool alternative. The Utili-Key looks like an ordinary key on your key ring, but contains six useful tools: a semi-serrated knife blade, slot, phillips and eyeglass screwdrivers, and most importantly a bottle opener. Stealthy yes, but don't try to bring onboard your next flight. (TSA no like.) Get one for $8.99 at Amazon.
