I forget the name of the weapon, but there is a sword that is fastened to a mail glove that I remember from another game. It cannot be dropped without losing the glove (which presumably goes up the forearm some length for stability), but can be broken like a normal sword.
I thought it was called a Manopole, but I couldn't find the word anywhere so I don't know if it's accurate, or whether the weapon really existed. It's not common and is not of massive utility, but I was thinking of using it as a villain's signature weapon and want to know how to rate it.
