william If you read up thread, Or rather if you did not read up thread, be really careful if you're using heat because you'll mess up the screen.
Use a metrocard, that's something that you have in New York, Or a wedge bar any plastic piece to pull it up. Even a playing card should help.
If you ever fixed any phone or have any plastic prybars that's the best tool.
Just curious what are you looking to do?
I would not advise you to use any metal knives or sharp objects you'll end up scratching the plastic screen and the real screen.
