Having just buying the first serious knife in my life, I checked out the videos from the local knife fighting school. Very disturbing. Not sword fighting but a cage match with sharp things. I have seen forensic photos of knife wounds and now I know how they happened. This not the stuff of the movies, and I have discovered that it is easy to find yourself, holding with both hands, keeping your intestines from hitting the floor. I have never understood knives and now I have much respect. Rather a sniper rife at 600 yards for me.
