Graphing Tool

As an engineering student, I spend my days doing tons of math and physics. I constantly have to draw graphs, and I got tired of sloppy, ugly graphs. So I made the Graphing Tool, which is a straight edge on one side and a notched edge on the other. The notched edge is for making the ticks on a graph, which I spaced out to perfectly line up with college-lined papers. There are 11 ticks, so it is perfect for a 10*10 graph, although you can make any size graph you want by leap-frogging (for a lack of a better term) the tool to extend the length. Additionally, there is a peephole so you can line up the tool perpendicular to another line, and a 5mm hole to fit a binder ring.
