Actually, I think the question refers to a weapon that looks like one of
those cheap paper fans you make in grade-school; pleated paper gathered at
one end so the other spreads out in a fan-type shape. Only it's about as
long as an arm. Sailor Mars uses it for a while in the Sailor Moon Final
Fight clone, and Akane used it on the copied Ranma-chan in one of the later
manga volumes. I could probably dig up the page (translation courtesy of the
Ranma 1/2 Project) and point it out, but based only on context, it's
probably got some demon-warding capability, in addition to being made of an
inordinately thick brand of paper.

Then again, what do I know?

Umm.. I may be wrong, but didn't the Koreans and Chinese use something
simmilar?  Fans with metal blades attached at the end to be used as
slashing weapons?  I know some parasols(sp?) were made into weapons that
way...
