I am not much of a "knife guy". I carry one for everyday cutting tasks but have never really considered it a option for a weapon unless absolute last resort. Well, I recently purchased a leatherman charge which I LOVE and never leave home with out. Since it has a knife blade on it I was considering upgrading my EDC knife to something a bit more geared towards a defensive role. I'm carrying a kershaw skyline now. Any suggestions for a more defensive style knife with a blade length around 4 1/2 inches? I'd like to go as light as possible and stay under 100.00 as well.
