Abstract: A marking tool has pigmented material integrally formed into a marker tool shape with various corners and edges that are usefully deployable. A planar body has spaced preferably parallel faces defining a thickness, and spaced peripheral sides oriented orthogonally to the faces. One or more sides can be curved. A number of straight or curved edges are formed between the faces and sides, with corners where three surfaces intersect and form a point. Some of the surfaces are segments that can be passed perpendicularly, at an incline or along the line of the edge to vary mark thickness. The marker is useful for drawing and shading when sketching, making lines in construction trades, arts, rubbing to trace bas-relief patterns, etc.
