ABSTRACT:
A tool for scraping coatings such as paint or paper from walls and similar surfaces comprises a housing with a flat guide face designed to come to rest against a surface to be scraped, two lateral housing walls extending beyond a transverse edge of that guide face and carrying a blade swingably mounted thereon with the aid of a pair of shanks having pivot pins received in slots perpendicular to the guide face to enable an adjustment of the blade position. The blade is externally concave between two working edges which are parallel to the transverse edge of the guide face and come alternately into contact with the surface to be scraped, depending upon the direction of movement of the tool thereover. An ancillary attachment, to be used in the scraping of curved surfaces, can be clipped onto the transverse guide-face edge and additionally supported by the convex side of the swingable blade.
