Since they all cause cancer, can't you just use a different brand?

Is there such a thing as a socket with a round base, or is this another "custom" tool that my grandfather made?

[crays]

What are the markings on it? Maybe he used it to seat bearings.

[Irving]

It's a 1/2" marked S&K Wayne 40416

[Irving]

Where do you find those?

Walmart, brand is Alexia.

More than likely used for bearing installs. Or he needed that size to press a sleeve in to a race, or pipe. With those old mc projects he had. Possibly used for pressing bushing in to shifter, cam and chain covers.

[crays]

Must be a custom job. I'll stick with my original guess of seating bearings, but that's a WAG.

ETA: 40416 is standard S-K part ID for 3/8" drive deep well 6 point socket.

I knew you smart fellas would know. I'm deciding if I should toss it or not. I'll ask my neighbor first.

custom tool, as others have said, probably used for pressing and not removal of bolts.

I had a brand new 13mm Snap-On wrench that the box end was just a round hole. Wanted to keep it for a conversation piece but the dealer took it from me to warranty it out.
