Any ideas what may have caused this?
Heat treatment or grinding error?
I have a PM3 LW from the 2019 2nds sale that is similar to this. It's not that the presentation side of the blade didn't get polished... It's that they took it to a belt and very carefully ground off some engraving of some sort that was near the Spydie logo. My best guess is that it might have been collector club numbers that didn't get sold, as I have ghosting on mine that appear to be just that, and my :spyder: is still somewhat visible.
