I don't know if there is really any difference in sharpening a ti screw compared to sharpening a steel screw.
That being said, here's a vidio on how to do it.

One thing to add:
IMO it's a lot easier to fix the dremel (in vice or whatever you got) and hold the icescrew in your hand to do the actual grinding (with the cutting wheel).
The surface quality is way better with the grinder than with a file.

NEVER sharpen your screws with a dremel or any other power tool. The heat ruins the temper of the metal and your screws are now soft and will get dull/bent much more easily.
Use a hand file and proper technique! Ignore both previous links. They have advice that's either wrong, or incomplete at best. Both give advice which is directly contraindicated by Grivel, BD, etc.
Here is a video BD put out on the proper way to sharpen screws:

Well that can happen if you do it wrong.
When done right nothing gets overheated and the temper is not ruined.
As a toolmaker I pretty much know how to use a file as well as grinding tools (like a dremel).
When I use a grinder the surface quality and the cutting edge are far superior to what I can achieve with a file.

Not everyone is a tool maker and spends his days precision cutting high temper steel. The average weekend warrior on this site would be best served filing by hand, slowly and deliberately.
