While fixing some ootb grinding issues, I ended up mucking up and needing to restore the damascus pattern on a Tanaka blue petty. I followed Davesí etching tutorial using a mixture of vinegar and muriatic acid (couldnít find the radio shack stuff) and after several tries, got the damascus pattern looking ok. I may do it again cause it came out a bit bolder than I had hoped for.
Q1. Is there a way to preserve the look of the damascus, while inhibitting the carbon natural desire to rust and reactive to acidic foods at the same time?
