Park Tool CNW-2 Chainring Nut Wrench

not a question but a comment. The product description says the tool is 9 inches long. I received it yesterday. It is only 4 1/2 inches long..bad!!!

Will this work on Shimano sora? I can't seem to find a flat head screwdriver that's wide enough.

I ordered this and haven’t opened the box yet, but realized it’s the wrong tool for the job. How can I return it?

Will this fit Campagnolo chainrings from back in the 1970's both road & track ?
