The kershaw is assisted-opening, which is about as close to being a legal switchblade as you can get - afaik. After a few weeks of working the action, it only takes a nudge with your thumb and the damn thing's available for use.

So, uh, yeah. I dont know how to fight with a knife, and don't want to learn. The knives aren't for the brown people. That's what the damn Glock is for. If I end up having to try to use the knives to defend myself, its probably over.
