I would DEFINITLY buy some if it was black titanium, or better yet black titanium with silver:

The only thing is the black part of the titanium is that it's a process or coating, it's just adding a non-value expense to the product. And it dilutes the value of the object itself. It wouldn't be .999 pure anymore.
