It doesn't matter what outlandish weapon a PC carries, the player will always want to use it to disarm an opponent at some point.
You haven't seen anything until you've seen someone try to disarm a dagger-wielding attacker with a pole arm.
GM: Obi-Wan, you sense the assassin behind you, pointing a blaster.
Obi-Wan: I spin around and disarm her with my laser sword.
GM: O-kaaay... Roll.
GM: Right, you cut off her hand.
Obi-Wan: Oops. Sorry.
Zam Wessel: Another operation to pay for! Nooooooo....
Anakin: Jedi business. Nothing to see.
Bar Patron: Yeesh! Remind me never to do business with the Jedi.
