Boxer® glass cutter with wooden handle

Before starting, you can dip the glass cutter in kerosene, then it runs best. Then hold it vertically and guide it along a ruler. You need to press evenly down against the glass, so it sounds like you're ripping a piece of fabric. Then tap the back of the glass with the glass cutter along your track. If the glass does not break, place it on a table edge and break it along the track you have cut.
