I've used scrapers of all kinds for over 55 years in woodworking, cabinetry,cast iron surfaces, paint surface prep, etc., and I have to say that the Bahco 625 scraper with solid carbide blades is the best I've ever used for paint surface preparation and scraping old paint from small and intricate surfaces. The blades hold their edge remarkably long, and the ergonomic handle design is a delight and restful for this old arthritic humanoid!
