I always carry two knives, one to use for everyday cutting tasks and one that I will only use if I have to protect myself. the knife I currently carry for cutting stuff is a BM griptilian and the one that i carry for SD is the AFCK2. I also sometimes carry a spiderco matirarch for SD. I just think that its important to have a SD knife as sharp as posible. example; if your attacker is wearing thick clothing such as leather or many layers. I would want my slashes to go right through like butter. I am sure that a properly sharpend AFCK2 could do this with out a problem. As far as a stabbing attack most knives should be able to handle this edge or no edge. I just wouldn't want to be limited to stabbing in a life or death situation. Leave nothing to chance I guess. What do you guys think?
