A straight edge is not needed to make a straight edge. A straight edge is but a convenient tool to make a straight edge. A simple understanding of mathametics will show you how to measure and make a perfect straight edge of your own, if you so desire. Or, you can buy one at the store and wonder about it's greatness.

A plumb line. Any heavy weight on a reasonably fine string will pull the string perfectly straight.
