I got a set, three different scrapers. I used the curve (like a french curve) inside to scrape the edges. Worked good. One problem I am having is getting it really sharp. It is hit and miss so far. Though I have read several web pages on sharpening it I only get a small burl and have yet to pull any long, planelike ribbons of wood. Most pages I read said you need a special hardened burnisher to pull the burl. A screwdriver isn't hard enough to do a good job.
