Though to be fair, there's nothing saying his sword doesn't have any special properties either. It is considered a "Sword of Kusanagi" after all, just like Orochimaru's and the Totsuka Sword. There's a tendency to assume it's just an ordinary sword because we've never seen it levitate or turn into a snake, but it's possible Orochimaru just never taught him those specific techniques.
