The swords you will see in Chinese Kung Fu forms are variants of two basic patterns: a curved, single-edged, saber-like broadsword (dao, often sold simply as "Wushu sword" or "Kung Fu sword"), and a straight, two-edged sword (Jian or Gim, often sold simply as "Tai Chi sword"). Some are bigger or smaller than average (the da dao is huge), but all that I have ever seen used in traditional Chinese arts conform to the basic typology of dao or jian.
If there are other major types of sword used in Chinese Kung Fu forms, I am not aware of them, and I have never seen one that uses anything like a katana, and it seems to me that Chinese and Japanese sword forms are quite distinct from one another. Of course, any practitioner of any art may pick up any weapon anytime. I'm just not aware that katana-like swords play any role in Kung Fu.
