i don't have anything to compare against but i got a pair of bahco scrapers from woodcraft and love them. properly sharpened and burnished they can really rip a ribbon of ipe off a bow. again, i have no scrapers to compare to. they're my first ones and i like them much better than scissors
ace hardware also sells a 5 pack of different shapes for a good price and i'd bet they would sharpen up just like mine do.
