Chinsese weapons : need some ID

[kisak]

The swords with knuckle bows might be hudiedao, possibly butterfly sword in English (I'm not sure what the exact definitions of those terms are, nor of they are exactly the same for the two words). The swords with the tips bent back into hooks are generally called just hook swords, I don't know hat the Chinese term would be. The remaining item looks a bit like something I've seen called a "claw spear" (attaching a picture of it), but I can't really see any claws in the same way on the one you posted.
