thread6-270316: Blade twist

Hi everyone,
I am wondering what exactly is the blade twist?
1. Is it a twist given to the blade during its manufacturing process? For example a geometrical twist at zero unstressed state.
2. Or is it the twist a blade can sustain with only elastical deformations to its structure? For example it is manufactures having straight (untwisted geometry) and then it can be twisted to the given angle without plastic deformation?

I suppose it is the first point, but I am not sure.
Thank you all in advance!
