sweet. I saw Alan Longmire (in a video talk about) one of those scrapers for putting the fullers in Bell-type dirks. Of course, the Bell Dirks had little blades, and therefore little fullers. I made a scraper a lot like that, only a little bigger scraping tooth, a few years ago. I used it and meant to keep it but lost it in the move to the new shop.
Still, they are not too hard to make. I always use old files for that sort of stuff. I use files to shape heat treated swords pretty often, and therefore I have a lot of worn out files. So, I use them to make all of my personal tools that I can.
great idea, the scraper, the knife series, all of it.
