When I was wiring up cnc's years ago I made up a tool for the same style of pin (probably should make another and show some photos).Start with a nail with the OD a tad undersize of the plug hole and then measure the shaft of the male and female pins OD and add 0.1 - 0.2 to that diameter and get a mate to machine (metal lathe) a hole up the guts of the perfect fit nail 0.1 - 0.2 larger than the pins OD. Then get a a bit of your wifes broom stick and cut 100mm off the end and then drill a hole a fraction undersize in the centre of the end of the new handle for the nail and press the nail in the handle.
One prefect long lasting pin remover for $0.00.
