This is a tool I modeled to fit in the back pocket of a "large" Moleskine hardcover notebook/planner. It has several functions:
Ruler: 7" in length with 1/16" increments
Protractor: 270 degrees of measurement in 5 degree increments
Compass: Two lines of circles, one every 1/8" and one every 2.5mm. Stick a pin in one end and a marking tool in the other and draw your circle
