Although jcyrus may be correct on the Phillips, for the exact tools you will need we need to know the exact machine you plan to get. Some require a Pentalobe driver. None require pliers. Some require the torx, some don't. Please give a link to the machine you are looking at. Installing your own RAM will more than pay for the saving over Apple installed RAM. Remember that you may have to remove the existing RAM so install the largest stick you can. We can also tell you the maximum amount useable in your new machine if we know what it is.
