Handle was "heated" with a torch and bent over to use in a tiny space.
Adapt Improvise and Overcome at it's finest.
I personally would NOT do it, but I have seen this done many times in the past.
I suspect you are 100% correct and makes sense too. They must have used it on a fairly large nut with lots of brute force, too. Of course, they may have tighten 2,000 nuts with this wrench, too.
My first thought when I saw this wrench for sale, was somebody got back at a co-worker, dropped this in his tool box in place of his prized possession wrench that never got loaned to anyone.
Thanks for all of the kind comments,
