If you're volunteering for the local rescue squad, your house is located along "Dead Man's Curve" and you keep fining rollover wrecks in your front yard, or for some other reason you want or need to carry some more serious rescue tools, the combination of a Halligan Tool, fire axe, and the hands-on training to use them safely and correctly, allows you force open a surprisingly large variety of vehicles, buildings, doors, padlocks and other things.

They'll cost you a couple of hundred bucks, but they don't take up a huge amount of space in your trunk, and they're serious, versatile tools meant for serious work.
