Combat focuses on disabling

The thing about the hand to hand martial arts employed by the Knights of the Round Table — and probably knights of the era of plate armor in general, now that I thought of it — was that it focused way more on disabling strikes than on lethal ones. And that made sense, because cutting or punching through reinforced metal plates was really hard to do. Instead, the goal became striking at vulnerable points, at forcing your enemy into a disadvantageous position where you had easy access to stab into the gaps between plates with your sword.
