Thanks, just slice a lot of acidic foods (which most are). Or just put some vinegar on a paper towel and wrap the blade and leave it a few hours. I just love the edge holding of 52-100 whether it's from BRKT, Swamp Rat, or now Scrap Yard. It's a great steel and I don't care if it rusts easily. Besides, as you say, the patina looks pretty good, too.
