"Abstract
A folding knife having a handle and a blade attached to the handle, the blade being connected for movement between a retracted position and an extended position with respect to the handle, and the blade a first locking profile, such as a notch. A locking member is provided having a second locking member, such as a projection, the projection being configured to be engageable with the notch when the blade is in the extended position. A pivotal connector is connected to the handle and to the locking member for allowing the locking member to pivot with respect to the handle. The locking member is movable between a locking position, wherein the second locking profile is in locking engagement with the first locking profile for locking the blade in the extended position, and an unlocking position, wherein the blade is movable with respect to the handle. A spring is connected to the handle and to the locking member, between the second locking profile and the pivotal connector, for pulling the projection into locking engagement with the notch when the blade is in the extended position.
