Mission Knives and Ocean Master each make titanium-blade folding knives. Other than expense, the tradeoff is in edge-holding. They're pretty much for applications where corrosion resistance is more important.. diving, sailing, or living on or next to salt water.

Mission knives are pretty darned expensive, but they get good reviews. I haven't tried one, but I don't think even their fans claim that they hold an edge like steel.

I have one of the Ocean Master folders- they're much less expensive (I think I paid a little over $50), and the handle is Zytel. I used to carry it when running, since it is very lightweight, I didn't expect to use it at all so edge holding wasn't a big factor, and anything I carried got covered in sweat- I managed to rust some stainless blades.

Ocean Master's site seems to be down right now, but here's a dealer:
