Ooh, I’ve never seen one of those previously.
And here’s me making do with a tommy-bar!
One of the most useful “special tools” I had was a plastic claw that would grip a screw-driver up to perhaps 3/16″ diameter, and the neck of the screw. The latter function was by three claws with an internal taper so it would unclip itself as you tightened the screw.
I bought it from a filling-station shop, but lost it long ago and have never seen an equivalent.
