Abstract
A liner for a folding knife includes a curved elongated spring to bias a blade of the knife to an open or closed position. The spring may extend in an arc from an origination point to a free end, within a cutout region of a body of the liner. The spring may be J-shaped in one approach. The spring may be integrally formed with the liner or formed as a separate piece which is attached to the liner. The free end may include a shoe to contact a lock stud in a handle of the knife. The origination point may be below and frontward of the shoe. The spring biases the lock stud frontward to lock the blade in the open position. To close the blade, the user moves the lock stud rearward, against a spring force of the spring, allowing the blade to rotate to the closed position.
