[Demloth of Dol Amroth]

the "swords are on no more use" might have merely referred to ordinary weapons-like a standard long sword, nothing outstanding. on the magical weapons question, perhaps depending on the wielder's power, it waxed and waned appropriately-but i recall the one case when turin wielded gurthang, and when he took his life, the sword spoke to him. considering that turin was a run-of-the-mill human, albeit one with skill in battle and such, he wielded no special powers that "people" like gandalf wielded, so we can only assume the power was in gurthang. i'd say a discussion of magical weapons needs it's own topic, though!
