Your index finger has many purposes; just add plus one to it! Thanks to the Finger&Ruler concept, you can measure the dimensions of an object by simply rolling the ruler over it. The wheel concept makes it easy to measure using just one hand, in lieu of the traditional tape measure and two-hands! Simple and functional, I really think this concept rocks!
The Finger&Ruler is a 2013 iF Design Award concept design winner.
