If you check Richard Binders's web site, you will see that modern MontBlanc pens have a "waverly cut" - the nib isn't bent, but the tip is ground to get some of the same effect:
After reading this, I examined ones I had (I have a few..) Sure enough, he's right - something I'd never noticed.
I recently purchased my first Noodlers Neponset. I would describe the tip to be ground the same way, though I think the Neponset nib is a little odd, and I think I will swap mine out.
Finally, I have had both Indy Pen Dance and Mike Masuyama custom grind and bend a nib to be a Waverly shape - I like both nibs quite a lot. They are somewhere between XF and XXF, but I find the Waverly shape makes them more usable than they would be with a regular bend.
