Initially, paper was ruled by hand, sometimes using templates. [1] Scribes could rule their paper using a "hard point," a sharp implement which left embossed lines on the paper without any ink or color, [2] or could use "metal point," an implement which left colored marks on the paper, much like a graphite pencil, though various other metals were used.
A paper-ruling machine is a device for ruling paper. In 1770, John Tetlow was awarded a patent for a "machine for ruling paper for music and other purposes." [1] William Orville Hickok invented an "improved ruling machine" in the mid-19th century. [2] As the device is designed for drawing lines on paper, it can produce tables and ruled paper.
The C-Thru Ruler Company is an American maker of measuring devices and specialized products for drafting, designing and drawing. The company was formed in 1939 in Bloomfield, Connecticut, [1] by Jennie R. Zachs, a schoolteacher, who saw the need for transparent measuring tools such as rulers, triangles, curves and protractors.
A rolling ruler is a ruler that contains a cylinder much like a rolling pin inside, thereby enabling it to "roll" along a sheet of paper or other surface where it is being used. A rolling ruler can draw straight, parallel lines, and also has other instruments included, enabling it to do the jobs of a protractor and compass .
A variety of chisels that can be used to craft designs into a variety of materials, such as tissue paper. Traditionally, papel picados are crafted entirely by hand. When crafting a papel picado, the first step is to draw out the selected design onto the paper and then cover the paper with transparent plastic; this will protect the original drawing.

When stencils are used in this way they are often called "pochoir". In the pochoir process, a print with the outlines of the design was produced, and a series of stencils were used through which areas of color were applied by hand to the page. To produce detail, a collotype could be produced which the colors were then stenciled over. [6]
For example, using a compass, straightedge, and a piece of paper on which we have the parabola y=x 2 together with the points (0,0) and (1,0), one can construct any complex number that has a solid construction. Likewise, a tool that can draw any ellipse with already constructed foci and major axis (think two pins and a piece of string) is just ...
