Treat it like any knife. Just sharpen it lightly. You don't want to wear the edge out too fast.
My brother in law visited Belgium recently and his friend over there gave him a small titanium pocket knife. The knife was very sharp initially but dulled quite quickly. Is ther any particular method to sharpen titanium knives? or do we just treat it like any ordinary knife. I'm pretty sure we just treat it like any knife.
Stay away from diamond stones or honing steels. Ceramic sticks and stones are best. Don't use anything magnetic.

like esav said. sharpen it lightly. i sharpened a knife zaph1 made from titanium and it was freaky sharp when i got done with it. i worked up a burr with a 400 grit belt before going to the slotted paper wheel to buff the edge. you might try stropping it instead of using any abrasive on it and like mossyhorn said, stay away from diamond stones. if you dont have any luck you can send it to me and i'll fix you up .
Diamond hones are actually the most recommended for titanium because its softness tends to cause rapid clogging of standard stones. If you have the need for it to be non-magnetic you will need a dedicated diamond hone that has never been used for a steel blade, but unless you are a EOD tech its not really a concern.
Remember when sharpening to use a light touch, Ti is easy to deformed and excessive pressure in sharpening will roll the edge causing difficulties getting a sharp edge.
bill, if you get some 3m wetordry sandpaper and a piece of glass that will work the best and be the cheapest route. titanium is not bothered by magnets either.

Stick with Richard or Esav's suggestions for sharpening and you will be fine.
BTW: Have you checked that the blade is actually titanium? If a magnet sticks to it, then it's not titanium. Titanium produces massive amounts of bright white sparks if you barely touch it to a grinder belt. If you sharpen on a belt, you will know instantly at almost any grit whether it's steel or titanium.
I have a small handheld conical diamond sharpener from Mission Knives to use on their Ti blades.
From Mission knives web site:
Titanium is magnetically inert, and is used by the Navy SEALs and Explosive Ordinance Disposal units (EOD) to defuse magnetically triggered mines. Knives must be sharpened with nonmagnetic sharpeners to remain inert.
i doubt that bill will have to worry about his knife around any mines
Sharpen it once to get the profile you want/need, then have the edge carbidized. It will be extremely low-maintenance from there.
As far as preserving the nonmagnetic attributes of a titanium knife, if it is really that big of a concern to keep it from being 'contaminated' (this all largely depends on what you would most use it for), use a dedicated sharpening stone for it. Doesn't have to be anything too expensive either. As others have said, sharpen it like you would any other normal knife.
Why would diamonds not be recommended?
