This weapon very much suits the design of that of a black knight, rather than a silver knight. think about it. The engravings and designs on it are very similar to the style of black knight weapons seen through out the game. The size would be appropriate for something of a black knight and yet again another thing. Havel was a close compatriot to that of lord Gwyn, and his black knights accompanied to the first flame. So the lore would have been better suited if there was this one knight called black knight Ledo, who was the strongest and gained the respect of Havel the rock. He did not wish to become ash, so he ventured the land and eventually became friends with the giants. That to me at least is a much better lore.
