This BodyGard 7-in-1 Emergency Tool @Brookstone.com would be the greatest Father's Day gift idea for any guy! It's got many, many features that would be life saving in case of a road emergency!

From www.brookstone.com:
When you’re trapped, seatbelt cutters are lifesavers.
* Micro-design fits easily in your hand or on your keychain.
* Quick release feature saves valuable time.
* Includes belt cutter, window breaker for car, flashlight, sonic alarm, and flasher.
* Also features a thermometer and tire gauge.
* Uses button cell battery (included).

My Review: I didn't know I needed one of these, but we usually don't know in a time of emergency.

Super useful and sleek looking! A great tool with lots of functions and safety features! (via Brookstone)
