ABSTRACT:
This invention relates to a mechanism in a folding knife that urges the blade to move to an open and alternatively to a closed position. The knife generally cnsists of a blade member having a tang extending outwardly from the blade; a handle having at least one recessed portion; a bar pivotally connecting the tang and the handle; and a bias element engaging the blade wherein the bias element is housed within the recessed portion of the handle. Generally, in the present invention, the blade must be moved manually a certain distance whereupon the mechanism serves to complete the movement of the blade without the application of further outside force by the user.
