ATS-34. At this point rather than make it worse, probably inclined to leave it. I changed the process a bit back where I mark the knife when done. Prior the blades were marked before setting the knife up so if it got messed up, that wasn't difficult to fix. Old stencil that becomes a bit fuzzy or clogged, etc. Going over it with 600 grit was easy.
Had good runs so shifted that to the final process. Life lesson to keep one alert.
