I picked up on this right away too. There's alot more going into a sharp edge than just material. How sharp you can make something is material dependent though. As a general rule of thumb with many exceptions the more brittle an edge is the sharper you can make it.
Imagine trying to make a knife out of a marshmellow vs a piece of glass. Even different steels can be sharpened different amounts. The more carbon in a steel the sharper you can make it. Whether Titanium and be made sharp I have no idea. It would make a really bad knife because it is so hard you wouldn't be able to sharpen it with most stones.
