my scraper is a brute that made from an industrial hacksaw blade. it's .090" thick, about 2.5" wide, and about 6" long. it's all hardened, which means that rolling an edge has to done with carbide, but this scraper will run a curlfor the entire length of the bow, if you can keep the pressure going! used in concert with my farriers rasp, i can hog off as much wood as i need, or i can remove very light slivers to do a final tiller!
