ABSTRACT:
Disclosed is a multistage pocket-knife being characterized in a pair of spring-supported balls rotatably received in ball holes formed on two side members of a knife handle and through holes formed on two lining members positioned adjacent to the side members. A blade of the knife is formed with several round holes near a rear edge thereof. Whereby, when the blade is in a folded position in the handle, the pair of balls extend a part thereof into one of the round holes on the blade and thereby firmly hold the blade in place without easily turning out of the handle even when the knife collides with something or falls accidentally. And, when the blade is in a process of extending or folding, the pair of balls engage into other round holes sequentially, permitting the blade to be safely extended or folded in more than one stage.
