Summary:A lock of the pin tumbler type having locking blades within a rotating cylinder. The locking blades extend on both sides of the cylinder and lock the cylinder against rotation when the key is withdrawn. Locking grooves in the frame receive the blades to prevent rotation. The locking edges of the blades, and the groove edges, are inclined slightly from the axis motion of the blades so that, in the locking position, the edges of the blades are wedged against the groove edges, preventing even the slightest rotation of the cylinder.
