My point was not to prove that the Nazgul could harm people. It was that it was mostly in the fear of them hurting you that did the damage. The same can be said with the dead men.

I would have to say The Silmarils, Grond and Angainor. But if it came to what weapon was worth the most I'd have to say Ringil, Fingolfin's sword. I say that because he did wound Morgoth with it.

Thats true as well. It's hard to put worth on these objects because they almost all played a part in the overthrow of Morgoth.
