I recently purchased and older SwissChamp with glass magnifier. From what I could tell, the only signs of use were minor scratches on the scales. But the file was just slightly bent to the left, and would tend to catch the liner sometimes. I ended to bending the file at the tang, ever so slightly, and giving the tool a good oiling. Now it closes properly every time.
Fixing it could be dangerous. You never know which bend will be the the straw that breaks the camels back. Generally, unless it really impacts usability, I find it safer to just leave these imperfections in that try to correct and risk snapping the blade.
Hi, if you bought the Workchamp for using it as a tool, I would keep it. But if you bought it s a collectors item I would return it.
