I would say this is a clear C-claw: http://www.chiefdelphi.com/media/photos/36495
Debatable, but yes (has only one moving jaw, correct?): http://www.chiefdelphi.com/media/photos/36531
No (roller): http://www.chiefdelphi.com/media/photos/36542

I think from the original poster's comments, he was meaning the C-shaped roller claw (like the third link you posted), though I could be wrong.

Regardless, I think the two most common types will be the C-roller, and the clamp with two jaws like you described. I guess they could both be considered "C claws", so it really could be the Year of the C Claw.
