'Lifetime' tool guarantees are often honored without any proof of purchase; Sears Craftsman tools are handled that way. Bring a busted Craftsman tool to a Sears store, get a no-questions-asked replacement. I'd be surprised if this wasn't Grover's way, too. Contact with Grover to learn how to invoke the guarantee ought to clear up the question.
