Funny you should say that Bob. I am in the process of making a new circle cutter for rosettes. My plan was to have the cutter und be spear shaped with bevels on one side only. You would use the bevel side towards the waste side by turning the cutter around depending on if you are doing an inside or outside cut. The other end of the cutter is ground like a scraper so you can flip the cutter over and scrape out the material between the edge cuts.
Perhaps I should look into making an iron that is the same width of my purfling that I can sharpen as you describe. My worry is that it will get narrower as it is sharpened and flattened. After a while it would not match the width of the purfling anymore.
