    Default How would you proceed?

    This Hilger & Sons model 2250 has a nice, very deep etch on the blade; here's what it looked like before and after a light cleaning:

    I'd like to address the corrosion ("devil's spit"?) and pitting, while preserving as much of the etch as possible.

    What would you do?
    When you are dead, you don't know that you are dead. It's difficult only for the others.
    It's the same when you are stupid.

    I wouldn't get much more aggressive, I would probably try very fine synthetic steel wool pads and metal polish

    I would use lapping film and wash it often. I wrap the film tightly around a round object. That is because the film does not sink into a deep etch. It will hit only the high spots. And washing every few strokes will keep swarf from abrading the surface edges of the etching.
    I have done this and it is good for deeply etched blades. Sparingly it will work for a shallow etch. It will not remove pitting within the etching.
    I have used a dental pick to get some of the pitting clean.
    YMMV as always!

    fill the etch with nail polish then use a hard backed fine sanding grit
    then clean up with acetone to leave the etching

    Looks like the devils spit pitting is probably going to run as deep as the etch itself. Taking the staining off the pitting will make it less apparent under some lighting conditions, but the pitting will cast shadows into itself, so you will still see it even if it's totally cleaned.

    Personally, I use 000 synthetic steel wool with MAAS. I made a thread about it with before and after pics in the resto section some time ago.

    Murphy's Law . " Devil's spit is always as deep or deeper than the etch. "

    Soft disposable wooden chopsticks & metal polish can get inside shallow pitting but won't remove it
