  • Patent number: 9573409
    Abstract: The present invention provides a drawing tool for an artist, draughtsman or hobbyist etc., the drawing tool comprising a handle and a retaining means disposed on the handle. The retaining means being adapted to releasably retain an elongate drawing material, such as a graphite lead, in an orientation substantially transverse to the axis of the handle. In use, manipulation of the handle and selective application of pressure to the elongate drawing material enables the drawing material to be applied to a drawing surface to thereby control the degree of shading on the drawing surface. The hand tool has particular application to reliably rendering gradients when shading with graphite and chalk etc. To be accompanied, when published, by FIG. 1 of the drawings, deposit varying thicknesses of graphite on the paper to modify the gradient of the shading.
