So, using a grinder you grind a curve into the small end, not the tang end, of a three sided file, a 6"-8" file is about the right size.

The curve runs from one of the sides to the opposite edge.

Sorry, still trying to visualize this. Is the radius to blunt the point in order to widen the scraping surface to avoid gouging?

The radius is to create a scraper cutting edge.

It is such as is found on a mechanic's bearing scraper.

At the moment I'm not at home, & will not be until March, then I can post a photo or two.
