HuFlung, I happened to have some pics of a file like you described on photobucket - it's a lot nicer than the commercial scraper and I 100% agree with your comments.
Remember though, he's using needle files so its easy to localize the removal of material. I assumed (yeah i know the joke) that they were doing it this way as it might be easier to start a beginner off with a needle file rather than a scraper, but admit were it me i'd for sure be using the scraper. sounds like with hold Hans on the job, they're lucky they're being allowed to use tools, much less take one of Han's files and smithy and grind it into a scraper
