Title: Folding knife with spring and cam

Abstract: The folding knife includes an elongated handle forming a spacing therebetween. An elongated blade having a working end and a tang at the opposite end within a common plane, a pivot including a pivot axis connecting the tang to the handle to permit the blade to pivot selectively into an open position at which the blade extends outwardly from the handle and into a closed position in which the blade is nested into the spacing. The blade is provided with a cam, that may be a rolling cam, secured to the blade eccentric to the pivot axis and spaced from the plane that includes the blade. An operating spring is secured at one end to the handle and has abutting contact with the cam remote from the end in the handle thus forming force vectors that are arranged selectively to resist the pivoting of the blade to an open position and when in an open position resisting the pivoting of the blade to a closed position.
