Yes, yes the curvature of a sword can be altered some what after the hardening process. In my previous post I wasn't trying to explain the entire smithing process just point out that the Japanese weren't stuck with curved swords because of the process, as was stated in this post:

I could be entirely wrong, but if you were wondering why straight swords died out in Japan, that's why. Swords with sharper edges were curved because of the process used in making the sharper edges.

Is it possible to make folded, differentially hardened, straight blades? Well, I made one when I took this course: http://www.youtube.com/watch?v=4l2PbvBeGkE
