Abstract
A folding knife has a slot disposed in the thickness of the tang with a roller cam extending outside of the perimeter of the tang and rotatably attached within the slot. A safety assembly disposed within the handle has a stud extending through a slot in the handle and moves the assembly between a safe and an unsafe position. In the safe position the safety assembly is forced against the tang thereby preventing opening. An adjustable bias element assists the blade in exiting the blade slot. The bias element is in spring communication with the roller cam. Applying pressure to the stud urges the blade from the closed position as the bias element is centered with the roller cam and the blade is forced to an open position by the spring force of the bias element on the roller cam.
