Blades vs Cavity Back irons - some questions...

Is it really easier to "manipulate ball flight" with blades than with cavity back irons? If so, why?

If a manufacturer made a cavity back iron with the same dimensions/offset/sole design etc as a typical blade, would the blade version still be better for those looking to manipulate balls flight? If so, why?

I am trying to understand if there is truly an intrinsic advantage to bladed clubs for better ball strikers, or whether any such differences are - in truth - largely explained by characteristics unrelated to construction eg face size, offset, sole design etc.

Thank you in advance!
