The new titanium Tiroler ring fixes that by adding the ability to take measurements to your EDC kit, with a smart portable design.

You know the issue. Even if your EDC multitool has a ruler built into it, it's usually not very long, so you wind up measuring things in three- or four-inch increments, no matter how long they are. Enter the Tiroler, a titanium ring which is currently on Kickstarter.

The ring is designed so that as you hold the outside of it, the inside wheel is free to spin. As you roll it along a surface, that central wheel, which is marked with either an imperial or metric scale, turns.

The numbers are displayed through a small window in the outer ring and each time you complete one revolution, you get what the makers call "a satisfying click" that helps you keep track of how far you've rolled.

For the metric version, that click is delivered every 10 cm. The imperial version clicks after every five inches rolled.

So for example, let's say you were using the imperial version and measuring the edge of a piece of furniture. If you heard six clicks and saw the number three in the window, it would mean that the edge was 33 inches long because 6 x 5 equals 30, plus the extra three inches shown on the device. It's a clever way to pack pretty much limitless measuring ability into a very small form factor, as long as you can keep track of the clicks in your head.
