Pitting on blade was quite deep and distributed evenly, blade had also frown. Very bad combination.
After cleaning and some hand polishing decided to fix frown and enforce patina. Mustard and vinegar in random order, by the way my first attempt and I am positively surprised by effect.
Buckeye burl finished with Hard Wax Oil.
I only set bevel before enforcing patina, so now need to refresh bevel and then full progression.
