Consistent-motion Ruler

There is always going to be a limit to the length of a ruler, unless something clever comes our

way. The Consistent-motion Ruler is clever and innovative. It has moving parts that require your

thumb and index finger for support. Simply adjust them along the length of the ruler and keep

extending the line. Fantastic!
