The Emerson designs from Zero Tolerance are the best production versions. If you want something truly exceptional, and like the designs, I'd say skip the headache and get one of those. I haven't bought a Kershaw in a while, but I think you got a lemon.
Have you tried pressing the domed side of the pivot onto a piece of leather then adjusting the pivot screw? I suppose something sticky or tacky could be used as well (like those lid loosener mats we all have in our kitchens.) Adjusting the pivot screw can help centering on folders.
Then just sharpen it up and the knife should be how it should have been out of the box.
