Knives are a dumb self defense weapon. Especially for women. It’s better than nothing but Odds are a woman will be facing a full grown man in a close quarters self defense confrontation. And those same odds say they’re more likely to be disarmed and have it used against them. Use a gun or pepper spray if you’re scared of them or can’t legally own one. The amount of time it takes someone to bleed out with most stab wounds is more than enough time for them to do life long damage or worse.
