For those who don't know: the head of the screw will literally accept a slotted, Phillips, or Robertson driver.

Milwaukee (popular among electricians) now makes a screwdriver that's the union of those shapes that they call an ECX screwdriver.

I bought a Klein version of that screwdriver and it’s a joy to use when wiring up receptacles.

I'm not sure if you mean the union or intersection?

I searched for ECX and it returns images of multi-bit kits. Could you link a photo of what you're referring to?

Several of the combo bit types are covered here: https://m.youtube.com/watch?v=4WsTfJ-YwbM (start around 2m59s, but there’s a lot of good content there)

Search "ECX screw" on Google images, it has some pictures of the bits and the screws

Thanks! That driver bit is crazy.

It’s actually quite nice if you do electrical. Recommended (also a “demo driver” whilst you’re at it).
