The first law of knife-fighting is never to lose concentration: always keep the whole of your opponent in view. Your eyes should not simply watch the knife hand, but take in the face, eyes and feet all at the same time, for it is often a hand or foot movement, or a sudden shifting of the eyes which signals your adversary's next manoeuvre.
