  • Patent number: 4268963
    Abstract: The hand tool comprises two members, for example male and female blade members in the case of a garden pruner, each formed with a tang portion which extends within a handle. For locking the members in a closed position, a catch pin is slidable in a slot of one member to engage a recess in the other member. The catch pin has enlarged head and foot portions which enable the pin to be inserted into an enlarged end portion of the slot before fitting the members together, and the overlap of the assembled members prevents movement of the pin into the enlarged slot portion after assembly, and so retains the pin in the slot.Mutually opposite recesses in the tang portions of the members assist in retaining the handles on such tang portions and form seatings for a barrel spring by which the handles are urged apart.
