Abstract
A scraper tool particularly useful for hand deburring holes as well as concave and straight surfaces includes a scraper blade being integrally formed with a front part, an intermediate part, and a back part joined to a shank at the back end of the scraper blade, which shank is fixed to the handle. The front, intermediate and back parts are all of triangular section and define three exposed, continuous sharp edges extending axially of the scraper blade. These sharp edges converge toward each other at the front part and coming to a point at the front tip of the scraper blade, are parallel to each other at the intermediate part, and converge toward each other at the back part to the juncture with the shank.
