A Weapon-Based Axe Enchantment: Disarming

Viking war axes (I know Minecraft has nothing to do with vikings but still) seem to have a bit of a hook-like underside. You could probably use that little hook-like underside to catch somebody's weapon and pull it out of their hand, giving you an advantage.

Now, in Minecraft, although there isn't as much of a hook-like underside to the axe, it would still be interesting to have the ability to remove the target's currently equipped weapon from their hand.

The disarming enchantment is applied to axes, and gives the player a chance to pull the weapon out of any mob's hand (if it has a weapon). This enchantment would not work on players, for balancing purposes.

There could be multiple levels to it, with higher levels giving you a higher chance to disarm mobs.
