The type of screw shown is NOT intended to be removed and I doubt there is a removal tool that will work well. Some types are intended to be removed for repair BUT NOT by Joe public and special tools are available BUT NOT THIS TYPE ! Good luck and devious means. Noel.
I normally use a Dremmel type tool with a small parallel bur to removed the anti-clockwise ramps, and then use a conventional screwdriver.
It’s a bit easier to see the screw head, now that I have a flexi drive and a dentists andge head drill.
