This fabled "Fin" again

Has anyone actually got a magnified image of this oh so delicate and prehensile thing?
I can only base my opinion on what happens with my sharpening routine and this has never been affected by before and after stropping. If I could see this "fin" it may help me understand what Dovo and other rest period advocates are on about. Pictures of it deformed after a shave and after 24 hours would go some way to alleviating my doubt on the whole theory.
If this "Fin" is nothing more than a very fine bur left by slight over honing...well you can guess what I would recommend
