Bout the same story. I used to carry a 2 and half inch folding knife back in high school because of street gangs. Now i have a baseball bat in my car (to tenderize any abnoxious bastard who thinks he can "road rage" at me :|\ ) and a tear-gas spray, which btw i think its been long expired
Ive never gotten into a fight though i punched a dude back in school. Ive been threatned with a knive once though but managed to escape.
