Abstract

A T-handled scraping tool has a thin, razor-like scraping blade securely fastened to a blade holder so that a narrow margin of the scraping blade is exposed. A shaft is mounted to the blade holder and extends therefrom to a distal end. The scraper is provided with a handle fixed in swiveling relation to the distal end of the shaft. The handle is attached to the shaft at a center of the handle and has opposite arms extending from the center of the handle away from the shaft. The handle is free to swivel around the shaft when the handle of the scraping tool is grasped by one hand while the scraping tool is moved in reciprocating motion over a surface to be scraped.
