Katana is designed as a slashing weapon because of poor quality of Japanese iron ore and process of manufacturing, where steel of different hardness is layered to give a hard but brittle edge on a softer bulkier back. When a sword cools down, the back contracts more than the blade, giving the sword curvature. This wasn't necessary in, say, Chinese swords, due to higher ore quality, and they are generally straight.
There are, however, other weapons that are much more obviously made for slashing and crowd control of unarmoured opponents (i.e. peasants); the southern Indian urumi, made of very soft steel and extremely long, basically a cross between a whip and a sword.https://youtube.com/watch?v=uZ0Nc2kHba4 [Embed]https://youtube.com/watch?v=eMAsCuDFSUI [Embed]
