A hand-held scraper tool having a handle and a blade clamp and having a blade whose cross-section is in the shape of an arrowhead on a shank. The arrowhead shape of the blade has a blunt rear end that is sufficiently thick to deflect scraped material away from contact with the region of the blade clamp gripping the shank, to provide improved scraping efficiency and to minimize damage to the underlying substrate. The method of using the scraper blade and scraper tool is also within the scope of the invention. The invention avoids the problem common to prior art scrapers which are susceptible to chips or pieces of the scraped material becoming jammed between the blade and the gripping jaws of the scraper tool, causing blade misalignment that results in incomplete scraping and/or damage to the underlying substrate.
