A good spudger set will include some of each tool. You will want to look for a set that has metal spudgers, nylon spudgers and plastic spudgers. The larger set you get the better off you will be as having each of these tools available at your disposal will help you determine which tools you will use the most. In some cases you will have to replace spudgers if they get worn down or damaged in a repair. When this starts happening, rather than buying a brand new set of spudgers you can buy the tools you use the most in bulk.
