That's a change purse or wallet here, pretty much. A purse is a ladies handbag type thing. As for the knife in my boot, why not? FYI, I do know how to use it. I'm not always walking in the best part of town doing my thing. I do keep my head up and my ears open, but a little extra protection isn't a bad thing and a service utility boot knife is legal in most places I go to. Besides which having a couple of knives is handy sometimes. I also carry a Swiss Army pocket knife with a bunch of tools in my jeans pocket just in case I need it.
Oh and like Indy, no kidding, when I am really out there away from home, I'm talking nature hike time here, I usually do have a leather whip in my pocket. I actually got that as a joke a few years back, BMF, to match my hat, jacket and backpack. I barely know how to use it. I rarely take it out, but it has come in handy once or twice, grin. I've scared off a wanna be bad arsed pup or two with it.
I believe in being "armed" up and to a point when I am wandering around. I'm somewhat little, and I've found that life can be unpredictable no matter what you do to stay out of trouble. I don't particularly like guns, but I do like knives and other weapons. I also have a big walking stick that I carry a lot. It mostly serves as a cane when I need one, but I could also crack a skull if I had to with it.
Short of someone brandishing a gun at me, in which case they can have the darned wallet and my gear, I do want to be able to fight back. I'm no one's victim if I can help it. Wandering all over unprepared to defend yourself in this day and age isn't too bright, particularly if you are a woman and therefore seen as more vulnerable.
