No both demon claws (bladed thulian calws) and JoJo claws are primary hand only...jojo claws are basically demon claws (BTC) with 1 less dmg =\ good for pets or people who cant kill the AoF yet
Stats on claws are not that great and are 4dmg 19delay magical and follow the same rules of BT claws that they can only be held in primary hand. Also, his spawn seems about 20 min or so, and is easy to get
