One of my custom pearl inlay damascus 3 1/2 folders. I just toss it at the antagonist and while he is admiring the workmanship, I run like hell the other way.
HEH HEH!
What do I carry for self defense knife-wise? First of all, I have inadequate training in self defense with a knife, so I don't take my skills in the area very seriously, if I use the blade it's going to be as an entirely last ditch kinda thing. Ok now...
1: Microtech LCC, Emerson CQC7 /w wave, or a BM AFCK, sometimes all three if I feel insecure, or just want alot of toys to play with while I have nothing else to do.
2: I carry them clipped to the pocket, usually if I carry the LCC/AFCK and CQC7 I carry the LCC or AFCK in the right front, and the CQC7 in the left front at the front of the pocket. It's a neat trick to wave the CQC7 out in a reverse grip. Some people use that method for getting at attackers behind them, but I think it's also useful for normal cutting chores if your right hand happens to be tied up. Just wave it out, switch to a forward grip, and you're set. I don't use sheaths because I haven't seen a sheath that's not uncomfortable to wear.
3: As I said, I don't take my skills using a knife as a weapon seriously. If I could get good training I would. But it's much too expensive considering my current income. That being said, I carry a knife because I haven't yet acquired a handgun of my own(the income problems), or a concealed carry permit for that matter. Even then I would still carry a knife, because I would rather have a knife, which is easier to manipulate, should an attacker be right on top of me. Again, that's only my admittedly half-informed opinions on the subject.
