I'm moving to Philadelphia soon. It's in a nice neighborhood, but obviously I'll wander into bad territory eventually. I have a passing interest in martial arts and self-defense techniques, so I know enough moves to get me out of some situations, but I'm a skinny nerd with mediocre strength. Whether I'll use it or not, I want to keep a weapon with me.
PA law forbids blackjacks, sandbags, and tasers, and Philadelphia law forbids knives of any kind. I heard somewhere that extendable batons are also considered blackjacks, and are police-only, which is a shame. I am personally opposed to carrying a handgun or other firearm, as not only would I need a permit, but attempting NOT to kill someone with a lethal weapon is difficult. This limits my options.
I possess a suburito: a kind of bokken (wooden sword) that is heaver and has no guard. I bought it from a novelty shop, and the craftsmanship shows with very small imperfections in the handle. That means it might break or shatter if struck with a pipe or well-made baseball bat. However, I know good soft-parries, so this piece of wood is better than nothing.
What problems do you foresee with me carrying this on my belt at all times?
