Abstract
Examples herein include systems and methods for severing a cable to retrieve the cable while leaving the head and downhole tool in a wellbore. A cable cutting device for severing a cable configured to provide support in a well includes a head, a rope socket assembly configured to engage an end of the cable and configured to be at least partially supported by the cable, the rope socket assembly positioned within the head, an actuator device that selectively secures or releases the rope socket assembly relative to the head, and a cutting blade configured to cut the cable. The cutting blade secured in an open position when the actuator device selectively secures the rope socket assembly relative to the head, and the cutting blade biased to a closed position by a tension force in the cable when the actuator device selectively releases the rope socket assembly relative to the head.
