What is the actual length of this item some websites are saying he is 29 inches is he are is he 21?

Does this come in a silver / steal colored ? Cant tell how f it’s black or silver based on mixed pictures

Can one actually use it to clean the fireplace, or is it only for decoration?

Will this rust if used with an outdoor fireplace?
