I did not know CNF is already available for industrial applications let alone commercialised ....as long filaments and not juszt as paper / filtration medium.

Well, it is. And Butterfly is not only manufacturer that is using it in making blades. I saw a photo of a CNF sheet Darker shared at the beginning of October 2019 and their CNF blade will be available during this Spring.

By the way, Butterfly has just announced these new products:
