What has happened is that there are too few parents who do things and have their kids helping.
I loved the line, "An extra large ratchet uses a 3/4” nub, but these are very rare, unless you work on airplanes or live on the planet Hoth." I'll have to go out back and check for the airplane; I hadn't noticed one, and it would be cool to have one. And it doesn't get cold enough here for this to be Hoth, so I must certainly have the airplane. Hope it's a good one, like a Sopwith Camel (gratuitous picture of Sopwith Camel here).

Granted, I don't use my 3/4" drive set* often, but it's one of those things that, when I need it, I
need it.
Also, a quick show of hands: how many of you have seen an adapter that will go from 1/2" to 1/4"? And, for bonus credit, if you had such a thing, how many small cap screws/bolts could you break off in one afternoon putting a socket suitable for a 1/4" drive set on a 1/2" drive ratchet?
*Thank you, Uncle Charlie - I got both my 1/2" and my 3/4" drive equipment from him.
