So let me think about this...

...I go to someone's house, and they have a sword hanging on the wall.

"That's interesting", says I. "What is it?"

"Ah, that's a replica of Aragorn's sword from Lord of the Rings"

"So it's a replica of an imaginary sword owned by an imaginary hero from an imaginary place, right?"

"Er - yes. But it's really cool."

Riiiight. I'm with the original poster. Never mind the legality or the safety. Massively, massively uncool works for me.
