  • Method and apparatus for securing a tang to a formed handle
    Publication number: 20020066189
    Abstract: An implement having a handle, a tang, and a working portion is assembled by snapping the tang into the handle. The tang has prongs that snap into a locking structure within the handle. No attachment hardware such as rivets or adhesives are necessary to secure the tang to the handle. A method of securing the tang to the handle includes snapping the tang into the handle with no further installation steps required. In a preferred embodiment, the implement is a fixed blade knife having a blade with a tang and a sharpened end.
