What kind of multi tools do you guys carry. I carry a Leatherman Blast on my belt and use it pretty much daily. The only place I do not take it is into the classroom at my UNI.(I leave it in the car) I love it and don't remember life without it. My next question is, are these legal to carry within reason? I use mine at work and for my volunteer work and can have people vouch for this if needed. Just want to make sure I am not breaking the law, after all ignorance is not a reason to break the law. I could not really find much on the net that was helpful other then UK stuff. I am interested in US laws, but feel free to share your countries laws as well.
