Take a skinnie cheap flat screwdriver and cut a split in it and slide it to the curve part of hook and hold line with same hand and it will pop out. It is best to get a screwdriver that is about 6 inches ,more or less. I still use the screwdriver for quick light turning screws,too lazy to go to tool box and get another screwdriver that is already in boat. I cut slot with my handigrinder but can be done with hack saw.
