Inchworm

It's been a long time since keychains were used strictly for keys. The average man's Batman utility belt, they're good for holding keys (obviously), but so much more too. You've got bottle openers, knives, vacation souvenirs and now, a ruler. The Inchworm is a 3" measuring stick made of rock hard, corrosion resistant 6Al-4V titanium. With grooves cut every 1/8", you can use it for quick measurements, product comparisons, depth checks and in a pinch, drink stirring. Would Bruce Wayne ask for measurement help at Home Depot? Now you don't have to either.
