A spudger is used for cell phone repairs and the repair of other electronics. Each spudger has it's own purpose but in general they are for prying apart pieces that are secured with adhesive or glue as well as working with electro-static sensitive devices which could include a logic board, motherboard or any other type of circuit board. These tools allow you to push, pull, connect and disconnect components from a PCB. These can also be used around the house and can come in handy during DIY home repairs and other projects.
