Why did Godric Gryffindor have a sword made for himself in the first place?
In the series, the only example of a wizard using muggle weaponry I can think of is Bellatrix Lestrange and her knife - being an evil sadist, she would probably enjoy using one against helpless victims because it's more gruesome than the relatively clean (if more painful) crucio curse. I can see why she'd use a knife.
The valiant Gryffindor wouldn't want to cut someone up, so why did he ever acquire a sword (and an expensive goblin-made one, too) instead of relying on magic for self-defense? Did he predict its usefulness to the future generations, or was it just meant to be an accessory, or what?
