I have some valuables in my home but nothing worth risking my life over. Likewise if I was walking down the street and robbed at gunpoint or driving in my car.
What I can I, in the situation of being subject to an armed robbery, do to increase my chances of not getting killed?
Keep in mind that “rapid deploy” knives, AKA switchblades, may also be illegal. Check local laws.
I always carry a Leatherman wave. If I was attacked and needed a weapon to defend myself, I wouldn’t open a blade on it. I figure I’m as likely to be injured by that as I am to injure an attacker. If anything, I’d just hold it closed in my fist to do more damage with punches.
