I do not use Solid Edge, but presume it has similar features as SolidWorks. I attached a Tutorial how I would create the blade in SolidWorks. Actually quite simple (so is everything else once you know how... right?).
In SolidWorks, you would use the "LOFT" Command. First create a series of parallel planes. On these planes you will create (sketch) a cross section (PROFILE) of segments along the length of your blade. Once you have the profiles created then you utilize the "LOFT" Command to create the blade.
For simple sake I just used 4 planes and 4 profiles for the example.
Hope this helps.
Create sketch profile on one plane
Finish all profiles on all planes
Create the "LOFT"
Thats it... enjoy
