Revolution Parabolic Blades

[idanceonice]

Can anyone tell me if these blades are labeled with the word parabolic on them anywhere?  I don't see it anywhere? They don't look parabolic to me but the rink says they are.

They are labeled with the word parabolic  

Similar to these in the sense that the parabolic "word" should be in the middle of the blade as well.  Also the blades are somewhat noticeable that they are parabolic.

According to the website, it looks like a parabolic option is available for the Revolution. http://www.mkblades.com/products/professional-revolution
