Abstract: A folding knife assembly includes a blade system which is disposable between an open configuration and a closed configuration using a single hand. The blade system includes a fixed blade member and a movable blade member, wherein the fixed blade member and moveable blade member are cooperatively structured to operatively engage one another when the blade system is disposed in an open configuration. The folding knife assembly also includes a positioning system structured to facilitate disposition of the blade system between an open configuration and a closed configuration. A locking system is provided and is structured to operatively engage at least a portion of the positioning system to releasably secure the blade system in the open configuration, and to operatively disengage the positioning system to permit disposition of the blade system into a closed configuration.

Abstract: A folding knife assembly includes a blade system which is disposable between an open configuration and a closed configuration using a single hand. The blade system includes a fixed blade portion and a movable blade portion, wherein the fixed blade portion and moveable blade portion are cooperatively structured to engage one another in an interlocked configuration when the blade system is disposed in an open configuration. The folding knife assembly also includes a positioning assembly structured to facilitate disposition of the blade system between an open configuration and a closed configuration. A locking assembly is provided and is structured to operatively engage at least a portion of the positioning assembly to releasably secure the blade system in the open configuration, and to operatively disengage the positioning assembly to permit disposition of the blade system into a closed configuration.

Abstract: One embodiment of folding knife using a mechanical linear slide action blade deployment system housed in a predetermined shaped cavity (28). Said slide action blade deployment system is comprised of a sliding member (1) made of a heat treated steel alloy and coated for low friction and high wear. Sliding member (1) is actuated by short linear thumb pressure on a sloped tab (5) located on top handle (2), thus transmitting sliding force from sliding member leading edge to blade opening pin (13) made of heat treated and coated for low friction and high wear attached to blade (3) axle at a predetermined location. This action causes blade top rotate out of handle to the locked open position. Thumb actuated sloped tab on top handle returns to starting position via a sloped tab return spring (16) housed in a cavity between inside top handle and top liner (11).
