Flattened a Chinese sharpening stone 220#( very hard) first with Naniwa flattening stone and the wet/dry silicon carbide sanding paper 80#.
After the silicon carbide paper I noticed that the peaks on the surface got glanced and covered
with a metal glancing look. Need to look sidewise in low angle to see this.
It has not filled the "valleys".
Don't really see anything when looking with a usb-microscope straight above but with a loupe looking side vise or just direct visual looking in low angle.
Anyone recognize this?
