A scraper tool particularly useful for hand deburring various surfaces at different cutting angles, includes a scraper blade of rectangular section defining four continuous sharp edges extending axially of the scraper blade. The thickness of the rectangular section is preferably larger along one transverse dimension than along the other transverse dimension of the section, with the larger dimension decreasing from one end of the scraper blade to the opposite end. The front face of the front end of the scraper blade is of rectangular configuration and forms an oblique angle to the plane passing perpendicularly through the scraper blade, thereby forming four additional sharp edges extending peripherally around the scraper blade.
