Ah, that is indeed an evil blade, every inch worthy of its wielder.
I still prefer the
Witch-King's sword to those of the rest of the Nazgul, especially for the cool designs on the crossguard and the middle of the grip, and the funky-shaped pommel.
Do we even see Sauron's sword in the movies? Or perhaps a better question would be, does he use it? All I remember was him swinging that big ol' mace around...
