Where do they manufacture the tennis racquets used by the professionals? - custom tennis racquets

In other words, what the pros are using bats made in China?

Is it true that Federer used as a bat, or use U.S. / Europe (Special, Custom) made snow?

Is there anything that any company that still makes more racket racquet U.S. / Japan / Europe?

Thanks for your answer.
