A scraper for erasing writings and drawings on paper, characterized in that its useful and effective element is represented by a bundle of long and equal fibers of plastic material held at its rear end by an elastic clamp; this clamp is only axially connected with a long pitch screw, threaded to a fixed element of the enclosing handle, and the screw is radially integral with the upper and rotating cap, but not axially displaceable, of the same handle; the lower part of the envelope affects the shape of a flattened nozzle that guides the fiber bundle; and depending on the axial position of the assembly formed by the screw, the clamp and the bundle, the lower end thereof is hidden inside the nozzle or protrudes more or less out of the same.
