While ubiquitous office binder clips are finding new legs as iPhone stands, they're simply not very convenient for those who need to carry bundles of documents around, as you can see below left.

Not to mention those are some good-looking triangle clips.
The same company that makes the ubiquitous black binder clips, Acco, has been making Ideal Clamps and other similar steel wire clips for years. I'm guessing the black clips have superior clamping force for large documents.
