I do agree with unbreakable's reasoning of "gun over knife", as I carry a firearm on me everyday as well... BUT..there can be times when your in tight spots and you do need a close-quarters type of weapon..In heavy, shoulder to shoulder crowds deploying something like a delica wave could possibly be alittle faster than trying to yank your CCW from under your shirt, jacket, on your ankle or where ever you carry it.. every second counts... even something like a kubaton would work wonders in these situations...If you draw your CCW in the midst of a thick crowd, you had better be very sure this situation will justify you yanking it out....or you will wish you hadn't... Of course the knife should be considered your "last resort"..But you should realize that it can very much be a weapon and a tool, and carry it as such...
