ESC,
I use a standard bench grinder, you could use an angle grinder if that is all you have. No need to polish after grinding. To use it, hold the glass in one hand, mark where to score with your thumb, with the ground surface of the file against your thumb, pull the file, with a slight rotation of the glass - using the file edge between the ground part & un-ground surface to score the glass.

My torch has a metal 'V' mounted on top, balance hot glass on it & score with the file, then the weight of the file is brought down to snap the glass - this technique is great for opening a closed pull point.
