What are good self-defense tools for women in Chicago?

Hi everyone, I’m looking for advice on self-defense tools for day-to-day use in Chicago. I have an FOID card but no CCL, and I’m not interested in carrying a firearm. I know stun guns and tasers are legal options, but I’m curious what others, especially women, are doing to feel safer while out and about.

Also, I don’t need comments like “stay alert” or “don’t go into bad areas.” I know this city well and am always alert, but even that can’t prevent some things. I’ve been held at gunpoint in Lincoln Park in the middle of a Sunday afternoon, so I’m looking for practical suggestions.

TIA!
