Is there data on RC hardness of DE blades?

This thought has been bugging me lately and numerous google searches are not turning up any information on the actual DE blades themselves. Just a lot of Hart Razor product descriptions.

Has anyone tested DE blades and published the data?

I have not seen anything myself. I guess coatings may confuse results, but worth looking into.
