Working with titanium is not for the faint of heart. The metal is hard enough to snub many of your tools, but if you have the patience it can really be rewarding. Take a look at this project write up making a ring from a sheet of titanium.
I don't plan on making a ring from this metal in the near future, but I love to read about the process and methods it takes to make a great finished product. Here's a video of the project, and you can go here to see all of the steps in the process.
