Great post Arahoushi. Only thing I wanted to comment on is saying there's just one Ninpo school. We actually have three. However, most people won't even see pieces of that until they're in their dans.
I swear, if a bell rang every time someone said a version of that statement on this site, we'd all be deaf.

As for the curvature, if artwork from the manuals is to be relied on at all then it's safe to say curvature varied from not very curved at all to pretty damned curved
I've also seen photos of one historical two handed saber that was highly curved that dated from about the mid 1500's.
There was also the dussack which is always highly curved in the illustrations, although whether the dussack was a weapon in and of itself or a training tool for the messer is under debate.
In the overall view of the curved 'sword' - I think of the simatar of the early arabian cultures - now THAT was a seriously curved blade.
I regret that I could not easily find a pic to link to - kept finding frogs and some form of antelope pics.
Although my specialty was never the sword - and more intense of Japanese blades - in my later years, I became more cognizant of the weapon known as a sword in different cultures and times. A few of you above are much more schooled than I in a certain understanding of specificis..and I thank you for you time spent posting - for I learned a few new things from you.
Respects tended and forwarded.
