"Micropitting" in Polishing
I just quit polishing up a nice Joesph Rodger and Sons 6/8 razor.
The original finish was a the factory grind that someone had scratched up somehow. There was never any black rusting or pitting to start off with.
I ground off all of the ?honing? scratches using 120 - 400 - 600 - chromium oxide - maas method that I've been pimping recently. I'm starting to have second thoughts about it.

By the time I finished the blade had taken a nice shine in most angles in the light, but at a shallow angle you could see little (for lack of a better term) "micropits". No reasonable amount of dremel work would get rid of them.
- Has anyone else seen these before?
- Is it a result of my skipping a bunch of steps (i.e. sanding with grits past 600)?
- Did the coarser 120 grit do something that you can only see after all the other scratches has been polished out?
- Is it just my razor (probably not)?
The picture I posted shows the 'micro pits' as a halo around the white reflections but they are everywhere (and a few other small scratches I will work on later). Do these look familiar to anyone?
Thanks,
Mark

Most finished blades have those "freckles"...LOLOL
Some just leave them alone to give the blade some "character", polish the blade to the best shine you can and enjoy it.
However if you really want to get rid of them so you have a smooth surface... you need low grit grinding compound mixed with your MASS.
Start with 220 grit (or lower) then 400 - 600 - 1000. Of course you will need a different felt pad for each grit.
Put that on the dremel felt pad and start grinding away the entire surface of the face till they are all gone.
Don’t even think about doing this with a thin hollow ground blade… you may grind the blade so thin that it would be useless… except for viewing in a display case… and that’s if you don’t grind a hole through the belly… OK for a wedge but still use caution.
It will take quite a few hours with the dremel... so long in fact that if you do, and polish to true mirror finish... you wont want to shave with it... ever... or do anything with it, for fear you will scratch it... and all that time polishing will be for nothing...
... however if you don't polish then there would be no FUN!!!
