So, a situation came up last night where a Villain disarmed a Hero. At the time, I simply had the Villain spend a raise to knock the Hero's rapier out of their hand (they were using a broadsword), and the Hero then spent a raise diving across the deck of the ship to recover it. 

While it resulted in a cinematic fight (the characters ended up swapping weapons and then the Hero spent a raise and a Hero Point to disarm the Villain and catch the sword in their empty hand), it seemed too "easy" to disarm an opponent simply by spending a raise.
