He needs that hand for reasons. Mostly masturbation.
@BigJohnson86, But he had his sister for that...
@SimonPetrikov, yeah but not anymore thus the need for the hand.
@BigJohnson86, I didn't know he had that GI joe Kung fu grip
Luke just can't HANDle the fact that kids were killed by that lightsaber.
@LightningBlade311, a second lightsaber would have came in HANDy in his fight against Vader
@WickedStyx, it's just a shame he got his a$$ HANDed to him.
Green is definitely the best Saber color. Red is a close second.
@Scottles, I prefer black.
