The present invention relates to cutting instruments, and more particularly folding knives which have a blade which travels between a first extended position coextensive with the knife handle and a second closed position with the knife blade at least partially recessed within a portion of the knife handle. More specifically, the present invention relates to secondary locking mechanisms to substantially prevent the knife blade from closing if the primary locking mechanism fails.
