Anyone know a good webpage with information about tactics with folding knives and such?
Not too sure about info exclusive to folders, but IMO if you get quick at bringing your folder into action, you incorporate the same techniques as a fixed blade with a folder. At least those techniques that aren't limited by the folder's ergonomics.
Kill or Be Killed
is an interesting read. 17 megs, kinda big, but IMO worth it. Can't really beat free.
