If I wanted to win a streetfight at all costs, I would bring my fathers siamese scimitar to the fight. However, it is heavy to carry around with me, makes unsightly bulges in my pants and makes it possible for the police to pick me up for being a looney. What is good and legal to carry with you for self defense? I tried fooling around with a key ring, it seems to me to work in theory. yes/no? Pepper spray is by the way illegal to carry here.
