Anyone knows how to use these discs?

[Oustoura]

Hi everyone,

i had some caoutchouc discs to clean up some of my blades which are pitted too much with deep spots/stains.

here a picture of the discs;



first i tried them on a scissors and the result was a little too much abrasive. i tought to use them for remove the metal on my razor blades and get them a mirror polish. but now i have no idea which processus to follow for a fine result.
