From what I understand, there are three rules regarding holding the striking surface of a weapon:
3.12.7. Combatants may grab their weapons any way they wish, including the blade/striking surface. This is an exemption to the anvilling rule (3.5.9).
3.12.8. Gripping the striking surface of a combatant’s weapon results in the disabling of that limb.
3.12.9. Contested weapons, e.g., weapons being held by two or more combatants vying for control, may not be held by the striking surfaces. A combatant who grabs the striking surface of a contested weapon must lose that limb.
My questions revolve around scenarios in which Combatant A is holding their weapon by the striking surface and Combatant B attempts to vy for control of the weapon by grabbing it.
• B grabbed the weapon by its non-striking surface.
• A was holding the weapon's non-striking surface in their other hand, then B grabbed the weapon by its non-striking surface.
• B grabbed the weapon by its striking surface.
• A was holding the weapon's non-striking surface in their other hand, then B grabbed the weapon by its striking surface.
For each case:
1) Does the weapon become contested?
2) Is the limb that A has on the weapon's striking surface immediately disabled?
3) Is B's limb immediately disabled?
