Nerd talk: (putting aside the ethics of the article), would that be a good or bad screw design compared to screws we currently have available?

Manufacturing the screwdriver/bit would be super easy, one pass with a flat bottom cutter to remove each quarter from the end.

The two remaining quarters of the bit being separated could maybe be more of a problem than if they were joined together.

You would get the same contact area as a flathead screw, but with only half the material behind it. But the bit would set so much better than a flathead and would not slide around.

I'm curious how something like this would compare to a hex or star screw. I would imagine a little bit worse, but the potentially easier manufacturing might make up for it.
