This one belongs to a new Aussie member , Mcduck. I have him to thank for the before pics as I always neglect that part. :p
I was 50/50 on going ahead with it but an initial bevel set looked promising. It was carefully un pinned & started at 400 grit.
Such a thin grind I couldn't start coarser but enough rust was removed & good steel was eventually found at the edge.
Scales got a light buff with the Novus 1,2,3 system & re- pinned.
Viola !
