There are other DF that reaquires outside object in order to use it. Although it does not specifically requires a certain tool like Leo's fruit, Kinemon needs to put something in the head of the target to make clothes for them. And Pica's fruit is useless in a place without a land made of rock (like the sea or a desert) and even a small piece of rock is not good.
