Some sharpening confusion

DD
>I'm hoping someone here can clear up some confusion I am having with sharpening scrapers. When sharpening scrapers, particularly round nose scrapers, I have always been told (and read) that one is to put a curl on the edge by burnishing it. This will produce a small hook that provides all of the cutting power for the scraper.

I have watched a couple of videos from tool manufacturers (Sorby in particular) that describe how to sharpen their scraper tips (like a teardrop shape for instance) that can be used with their hollowing tools. There they use a diamond file across the top flat of the scraper tip. That, to me, would eliminate the burnished edge entirely. Why the different treatment between two tools that are used to provide exactly the same cut? What am I missing? Any help appreciated.
