At one time I used to cut a lot of glass. There are at least two kinds of glass cutters commonly used.
There is the wheeled kind that has a hardened steel wheel to score the glass, then hopefully the glass will break along the score. And there the diamond tipped type of cutter that is dragged along the glass to score it. I've used both kinds but the diamond scoring cutter can more effectively score glass with less pressure. If you use the roller type of cutter dip the tip into kerosene some some other light oil to lube the roller. You can also cut glass with a carbide or diamond tip cutting wheel. I wonder what kind of laser they use to cut them since cutting shiny surface material can be tricky.
