The Hook- Hand is Jaller's left hand. After Shaller cut off Jaller's hand, he was given a hook. It soon grew a Protodermis shard on it which was the same one Barraki used to free Shaller from the Toa Seal, after Jaller came back to life after dying, it broke off because Shaller was his own person. Jaller made a replica of it as he found it useful. He use to prefer the hook, but found the claw more useful. It will soon feature a Cup Shield.
