@Don Kanaille:
I think we can already do that. It's all fencing, taking into account time, distance, flow, and structure.
I should have added that the maul can also hook. Any weapon where part of it sticks out a significant distance out of line with the handle can hook, thanks to physics and the bounding boxes of weapons following the shape of the weapon instead of being straight-sided boxes. The head of the maul meets this criterion.
But to make the hooking action happen, you have to combine weapon motion with body motion, either your own or the enemies. This because the swing animations have the weapon moving edge-first and then it goes straight back the way it came. So, to hook the foe, you must initiate the strike from inside your normal effective range, so you hit him with the handle, and just as that happens, you need to step back. This makes the handle slide on the foe until the shoulder of the weapon's head catches him, at which point physics determines what happens. But you can pull foes around this way if you're bigger/heavier, have enough backwards momentum, and the foe's feet are placed so that he's less able to resist the pulling force.
The problem with the maul is that it's go so much momentum from the swing that it's hard to move and swing it at the same time. Thus, hooking with it largely depends on the foe stepping back instead of you, which isn't so effective. More likely, you'll get more of a sideways push on him from the impact of the handle swinging into him than you'll get a pull back toward you.
The easiest things to hook are shields---in fact, it frequently happens whether you intend it or not. This is because when you launch an attack from the proper distance to hit the foe's body, his shield rim must necessarily be at the shorter distance needed for hooking. I find it best to do this with the 2H axe, however, because 2 arms vs. 1 means you generally win the tug-of-war and pull the foe off balance, and the 2H axe isn't bearded so comes right away and you can swing again to take advantage of the opening thus created. Using a 1H bearded axe against a shield is normally a bad idea because the axe will get hung on the shield for a long time, keeping you in close to the foe where he can punish you with his free weapon.
