An involute curve seems to describe that  curve better than a parabolic curve regarding Springbuck's post.

Anyone got a pic of a bow with such a curve?

I couldn't find a bow that has this specific curve, but here's an illustration that shows the shape of an involute curve:

Although, to my eye, that curve looks like a great shape for the reflex in the outer portion of a hybrid longbow.

 Talon bows were designed on this shape but on a less condensed scale. Google involute and you'll see it clearly in the way Springbuck describes.
