I've always loved the way swords look. So far I have about 6 swords and a bunch of shorter blades. I have a rather small apartment so it looks a little on the creepy side. :P
There's definitely an art form to sword crafting that show a great and deadly beauty. And in there perhaps lays the form of beauty, the fact that this construction of metal is a dealer of death. As well as the mystic of "the warrior" riding in to battle with his blade and courage for some noble cause.
