Taurus 3 Ringsaw

Literally cut any shape using the Taurus 3 Ringsaw (by Gemini Saw). 

It's an awesome tool for difficult-to-cut glass, or if you just can't cut glass with a regular glass cutter! 

You can change blades and cut just about any material as well. There's several specialty blades available. Check the Taurus Ringsaw Replacement Parts page for details.
