What is purpose of fullers on blades?

I've heard it posited that a well shaped fuller or groove can increase shock absorption of a blade. On the surface of it, mechanically this does make sense. A semi circular dish is basically a vault. And vaults are good at redistributing pressure through deflection. The idea of this would be that when you hit something, that you are less likely to feel the shock of an impact through the handle as severely. However I've never seen any experiments that test this. And so I must treat this as speculation.

Blood letting and air pocketing have the same issue to my mind. They are simply theory craft that have not been tested to satisfaction that I have seen. Anything that can be submitted without evidence can be dismissed without evidence. In other words if you don't see proof you are seeing an opinion. That is not to mitigate the value of the informed or trusted opinion. As those can lead to tangential learning.
