Is this rust or something else? (TI razor)

[CoffeeAddict24]

Hello,

I was wondering if this is rust or something else. It's a modern day TI Evidé Sonnant.

These marks appeared after honing on Naniwa 1K, BBW with slurry and yellow coti. I noticed the spots right after bevel setting on the Nani.










So, is this rust or something else?

Kind regards,
Mike
