Proto!
I still have a 1/2-9/16 box end, that is the only wrench I have remaining from my tool box that was stolen from me in 1961. It was full of SK 3/8 and 1/2 inch sockets and wrenches. (sniff )
The wrench has had a lot of use and is still in great condition. They don't build them like that any more.
