There is a lot of information out there about improvised weapons. Some good some bad. Whirli hit on a really good one with the belt. I live in Texas and big belt buckles are normal. They might stick out a little in New York though lol. I have seen several bar fights where they were used….not pretty. I actually used one to detour a big dog that came after me. It helped me keep him at a distance. Learning improvised weapons is a great advantage. You don’t necessarily have to be carrying something to defend yourself or you can carry something that no one will see as a weapon. When skillfully used a rolled up magazine can inflict enough damage to at least let you get away from someone. Michael Janich has some good info on this.
