The HammeRuler is built on the notion of Short-Measure Acceleration (SMA). By cutting down on tool switching time (from hammer to ruler and back) when doing short measures, the HammeRuler makes you more efficient. You probably don't realize how much time you spend putting down your hammer to pick up your ruler, and hammering back again huh? Well, here's a simple solution! =)
