A multipurpose drawing tool is provided. One embodiment of the tool that is advantageous for drawing circles one-handedly includes a protractor portion and an elongated radius arm portion. The protractor portion includes an aperture, and a securing member is rotatably mounted in the aperture. The securing member may be a transparent or translucent suction cup for releasably attaching the tool to a drawing surface such as a vertically-oriented dry-erase or chalk board. Alternatively, the securing member may be a transparent or translucent magnet or a conventional magnet configured with a generally annular or toroidal shape. In another embodiment, an improved protractor is provided that includes a straightedge portion, a semicircular portion, a pivot arm and a suction cup or magnet securing member that pivotally secures an end of the arm to a central portion of the straightedge portion.

A case for multiple stamp pads is provided. One embodiment of the case includes a first housing portion for retaining a first stamp pad, a second housing portion for retaining a second stamp pad, a hinge connecting the first and second housing portions for movement between a closed configuration where the first and second stamp pads are facing each other and sealed within the first and second housing portions and an open configuration where the first and second stamp pads are exposed for use, and a divider separating the first and second stamp pads in the closed configuration and swingably covering one of the first and second stamp pads in the open configuration.

A folding ruler is provided. One embodiment of the folding ruler includes a first panel, a second panel, a hinge and a stiffening member. The first and second panels are interconnected end to end by the hinge so that the ruler can move between a folded state wherein the first and second panels are generally parallel and overlapping, and an unfolded state wherein the first and second panels are coplanar and oriented end to end. The stiffening member couples with the first and second panels to lock the first and second panels in the unfolded state. In some embodiments the stiffening member provides a grip for holding the ruler.

A flat triangular piece, usually of shatter resistant plastic, is formed with straight edges and is used in connection with a T-square for drawing perpendicular lines and geometric shapes. The outside peripheral corners are rounded for safety purposes and the intermediate portions of the legs are slotted or recessed to permit the utilitarian reproduction of triangular lines and shapes with sharp points.
