The most basic one in my mind is the Chinese doa with all the similar variants from SEA meaning essentially the same thing. I cant think of any examples of a dha, daarb, man(dau) hwando or similar sounding weapons that are double edged. Most are primarily slashing or chopping weapons.
The two edged sword, jian or gim, does not seem to be quite so widespread with examples of the kiem in Vietnam, and I think it is a gum in Korea.
Then of coarse there is the keris/kris ranging from India to the Philippines.
Is this what you are looking for?
