How's the handle chamfer on the 21s?

I'm looking for some input on how the 21s handle edges and overall ergonomics compare to the older large Classic and the new Umnamzaan. It seems that the Umnamzaan has more of a rounded edge and easier on the hands then the Classic. There are less hot spots. How does the 21 with the new machining?

Don't know about the Um but I can't tell that much difference on the Sebbies. Sort of feel the same to me even though I know they are not.
