It is not only the hilt. The guard is also similar. And actually I don't remember any other sword with similar hilt. The common hilt design is the one the Wadou Ichimonji and ShuuShui have.

(If you have seen any other sword apart of Zoro's Kitetsu and the Bald Guys give me a reference... I'm interested to who has it.)

Also, since there are two more cursed swords and they are both of higher class I thought that Oda will show them in the hands of important people and not necessarily a pirate's.

Well, of course this is all just a hypothesis. But it would be interesting, don't you think? Also, if one of the top of world goverment has the Nidai Kitetsu (based on the guard design that I explained above) then who could have the Shodai which is the only known sword in the class of Yoru (Mihawk's sword)?
