The khopesh idea came only out of the suggestion of utilizing the "plowshares into swords" imagery, and since Melkor is looking over Fingolfin's shoulder while it is being made, I don't have a problem using a curved blade for the elves here. As to the subjective idea of how "bizarre" a sword is... I'm not sure what to do with that. It certainly seems, to me, to be a beautiful, elegant, and deadly weapon. I have no logical argument that can defeat a subjective opinion of aesthetics. As to the idea of assuming that Tolkien meant "large" when he said "mighty".... I don't think that we necessarily have to do that. The sword will be visually striking, and it is clearly a more versatile blade than the ones of Fingolfin's design. As to the idea of the Noldor basing their early weapons on the designs of the Valar, I remind you that the Valar are not bound by physics in the same way the elves are, nor by materials. Keep in mind also that in Season 2, the hosts expressed the desire for the Ainur to not be wielding physical, manufactured weapons. This is why we discussed all of this then.
