Probably the most important tool decision you make is your glass cutter. There are a lot to choose from. There are two things to consider. What the wheel is made of and which shape is most comfortable for you.
The heads will be either steel or carbide. Carbide is more expensive but far outlasts steel.
Most of the steel cutters are what people call “ throw aways”. That is because they do not have replacement wheels. When they get dull you just throw them away. The steel wheels come in different sizes and different angles. Some are better for soft glass and others for hard glass. The size and angle determine this. You can purchase a steel wheel cutter (at this writing) for less than $10.
The carbide cutters are way more expensive. Some can be in the $40 range. Many are self-lubricating which is very convenient. The most common shapes are pencil and pistol. There is also the saddle and then some more unique ones.
There are also specialty cutters. There is the Score 1 Cutter that looks like a sewing machine and scores by running the glass through it. There are circle cutters that cut score with either a single head cutter or with a wheel turret. There are circle cutters specifically for small circles. Some circle cutters double as a strip cutter. There is even one that doubles as an oval cutter.
There are also a series of cutter aides put out by Morton and Cutters Mate. These are things like jig systems and tools to help break after you have scored.
