    that's neat...it shouldn't be too hard to come up with a proper scraper blade for those oscillating multi-tools like this https://www.harborfreight.com/Oscill...ool-62866.html make scraping a lot less work!

    Great adaptation. I didn't catch source or material of cutter, I'll revisit. But that it works, best proof of all.
    And saved not less than $1000- $1500 US or more, on commercial [ie BIAX] power scrapers and flaking tools.

    There are steel and carbide tipped scraping and flake blades. The real trick is honing correct angle and fine leading edge. They must shear - not dig in or skid. Skids will pile up and produce false planes of contact.

    Having several blades honed to various curvature radius's and widths is an advantage when scraping or flaking different surfaces.
    gaining experience learning the angle to hold a given tool be it a blade a fixed to the end of a baton caressed in your arm pit or a power scraper is another key to achieving the desired surface finish
    Never try to tell me it can't be done
