I don't think there is a tutorial yet!  However, I can give you a few pointers if you like! 

Glass cutters score glass, or generally create the break mark where you are hoping the glass will come apart.  For most projects, you will need glass cutter oil, which is an oil that you will use in order to help the cutter move smoothly.  (The cutter in your picture can be filled with oil.  Other cutters require having the tip dipped in oil prior to making cuts.) 

When you have your cutter, go to the edge of your glass and cut in a little ridge where you will want your break to start from.  Then, score the line that you want to make.  You will then use running plyers to break the glass.  Voila, your glass is cut!

Thank you for all that info it covered most everything. If you don't mind I have a question or two?

- How thick can the glass be before you use a more heavy duty cutter?
- How often do the blades need to be replaced?

That should do it for now.

Hmm.  What are you trying to cut?  I use my glass cutter for stained glass and those pieces are generally all around the same thickness, though some may vary due to texture.  I also use them on microscope slides, which are much thinner.  Most glass is around the same thickness as stained glass, so I would imagine that this cutter would be fine for most projects.

As for replacing the blade-- I honestly have never replaced one before.  (And I've had it a few years--seems to be fine!)  If you are purchasing one, I'd recommend asking the place you are buying it from if they have any recommendations.

The one I posted is the one I have already. The glass is about the same as microscope slides, but I wanted to check if there is a limit.

Thank you again for all your help, and maybe you should do the tutorial

You're welcome!     I hope you post what you come up with sometime!
