God hands can be made by doing the quest "Soul of a blacksmith" and finding him the mineral. Give him a sword and he will make you God Hands. (Strongest Knuckle weapon in the game that I know of)
You don't need a sword as DARKMATTER pointed out. You just give him the blue material and tell him if you want a sword, gun or cane. Sword gives you the God Hands. Gun gives you the Suppressed Gun and Cane gives you the Technical Crozier (as pointed out before).
Also: Skyly has a 1/46 Drop Rate for the God Hands when fighting the Gal Griffon on Ultimate.
