Hand Scraped Finish?

    I stumbled across an old educational video, detailing a machining process called metal scraping. Using a surface plate, some Prussian Blue, and a series of tools resembling chisels, the machinist could achieve a completely flat surface. The process was also used aesthetically to create an effect called "frosting". It produces a really interesting surface patern.

    I was wondering if anyone knew of such a finish being used for a knife.

    I assume you mean on the blade ?
    The finish you mentioned is done on cast iron surfaces etc but I would think a decent knife blade would be nearly as hard as the tools used to cut the cast iron so probably not practical for a finish on a knife blade.
    It might look cool on a handle.
    I have never used these scrapers but have read about the process in my old machinist magazines.

    To me that finish would be used as a quick cover up so flaws could not be detected as easily as on a mirror finish. DM
