Do you own any? I always carry a small knife with me but I've been thinking about buy some other stuff. I think of them as armor upgrades

It does not say how small they end up being when they are fully collapsed, and I have to think about concealment.
They sell really big bolts at your local hardware store. They're like $2.25 and with a quality power grip made of duct tape, you'll let any attacker know that you're completely crazy and mean business.
Support your local merchants!
I don't feel the need to protect myself. Also, I'd rather not be charged for assault or some crap for defending myself with a knife etc. If someone breaks into my house I have a golf club and a few iron bars in my locker. But out on the street, nope.
hahahaha, bombs
