Please Help Identify a Mystery Craftsman Wrench

[NHtoolguy]

Hi Garage Journal Community, I need help identifying a Craftsman wrench I found at an estate sale. It has a single end box opening that I think is 1-1/8" and no offset. No size or part number markings are present. What was this used for? Is it a blade wrench for a table saw? Thanks for any input!

table saw or tool wrench

Might be used to tighten a Ball for a Trailer Hitch

I should add that the wrench is thin, about 3/16". It doesn't seem to be intended for high torque. That's why I'm thinking that it's a blade wrench.

My 1980-90s? table saw outer wrench is a stamped steel, not cast, but otherwise a good guess.

Pointy A, so it is fairly early.

Thanks Ed! It looks like you solved the mystery. It is a wrench for changing circular saw blades.
