yeah this doesn“t look that nasty! I hope you already started restoring the baby?
I had a bad case of pitting into the steel of the edge myself.
It was way worse than what I see here.
Parts/dots of the colmplete bevel where gone.
I just did some light strokes on my DMT 600 and after 5 minutes, they were gone.
I did a normal sharpening routine through to 30k and voilį, s'good as new
Go ahead and try, maybe even a 1k will do the trick
