I think one of the problems with trying to fit all razors into one definition of the various grinds is that though a particular type of grind has a textbook profile in reality each master grinder (or whatever thay were called) had his own idea of what constituted the best grind for a particular type and imparted that person's own ideas in each razor he produced. I'll bet if you at random took 20 razors of each type and looked at them under high magnification you'll see plenty of variation in each razor that departs from the textbook profile for each type.

Also as an aside here I have two framback razors and if you look at the profile of the entire razor once the blade extends past the frame both have no real contour to them. They are like a razor blade, just straight metal kind of like a feather I guess. So what kind of grind is that? I haven't a clue.
