How fancy do you want to get?
How worried are you about a few scratches?


I'd probably simply look for the pair of pliers with the most worn jaws and use that.


Although I thing I've seen pliers made for the purpose.


Maybe bring the Dremel out, grind a shallow groove over one or both of the jaws for better clamping force.


Or use a strip of sheet aluminium between jaws and spoke to prevent surface nicks.
