Spudger

A spudger (or sometimes spludger) is a tool that has a wide flat-head screwdriver-like end that extends as a wedge, used to separate pressure-fit plastic components without causing damage during separation. This is commonly used to replace broken cell phone screens and integrated batteries. The other end is often a point or a hook depending on application. When applied to separate pressure-fit panels, there is often a point to create an initial gap before the wedge end is utilized.
