you silly person, if you go into a knife fight, and the other person has a knife, you will be cut up even more if you pull a knife, cuz you know, knives are useless. if not, they will surely grab your hand and stab you with it a dozen times. yes, for your own safety, carry a double barrled coach gun, or nothing....there really is no inbetween. wildly slashing with a 4" folder will do NOTHING in a life or death situation. in fact, you are much more likey to survive a knife fight if you say, "darn it fellas, i dun forgot my m16 this mornin so i cant shoot ya. here, take my voyager i have clipped to my pant, so i dont further hurt my self, and THEN proceede with your slicin me to ribbons. see boys, i really dont want to get hurt, so by all means, cut away while i stand here and try not to hurt myself. what i really could use right now is a toothpick...or some shoe strings, yeah that would show you gang bangin scum. but alas, all i have is my JYD2".
id choose a police 3 g10. its large without being bulky, and is ambitextrous.
