Hmm, there's an item called the saw in the Enforcer class. Do you think that might be it?
Ease up a little. Unless you read through the different skill trees you'd never know about a saw.
TC: After you level up a bit you will be able to use a saw as a(n enforcer) skill, then you can open up those ATMs. You'll also be able to use it on safe deposit boxes and a few other things in the game.
