Remember the coolest geometry set you ever lay eyes on as a school-going kid? It could be something you owned, saw someone else own, or just glanced wishfully at while at a store. Now imagine all that coolness packed not into a set, but into one singular instrument. When I saw the Tiruler for the first time, that’s pretty much the feeling I got – that of awe, euphoria, and sheer desire. We’ve all seen folding rulers before, but imagine one that has a caliper, a pencil, a screw-driver, or a spirit level too. Sounds wild, doesn’t it? Now imagine the entire thing made out of titanium, so even though you buy it out of being an excited EDC enthusiast, you can pass it down like a family heirloom to your kids when they need a cool geometry set of their own.
Born from the engineering minds at MakerPi, the Tiruler represents a fascinating pivot into the tangible, analog world of everyday carry. With more than 10 functions built into its unique form, the Tiruler is like nothing I’ve personally ever seen. Every single inch of the gizmo hides a feature that gives the Tiruler incredible meaning and value… all blended into an industrial-steampunk aesthetic that isn’t merely a visual flourish – the exposed mechanics and dual-material construction telegraph the tool’s serious intentions while celebrating its utilitarian soul.

The best way to appreciate the Tiruler is to really look at all that it packs into its compact form. The device measures roughly 120mm or 4.7 inches when closed, opening up into a 200mm or 7.8-inch scale, depending on your need. The entire thing’s made from titanium with etched numbers, so you could use it to measure, draw, cut, or do anything without worrying about any wear or tear. The pivoting scale expands based on need, but here’s the kicker, it also packs both imperial and metric measurements, and that pivot? It works as a protractor.
The pivot features a brass enclosure with engraved angles that let you use the Tiruler to draw or measure angles. In all fairness, I had a scale/ruler that did this in school – but it was made out of plastic, had its fair share of errors, and wasn’t as immaculately produced as this. Here, titanium-machined precision makes the Tiruler fantastically accurate. Want me to elaborate? The thing has a literal vernier caliper built into it too! But we’ll get to that later on.
Along the pivoting mechanism is also a rolling scale that lets you measure non-linear surfaces. Perfect for curves, or just measuring something you can’t hold a scale to, the rolling scale lets you roll along the line you want to measure. Every time it completes a revolution, it clicks, making keeping track of measurements easy. This effectively means you can go on measuring indefinitely – just count the clicks and then look at the final number on the roller to get your overall calculation.
For more complex measurements, an integrated vernier caliper gives you the ability to do stuff your regular ruler can’t. The caliper’s jaw sits inside a perfectly machined slot on the Tiruler, sliding out as much as 50mm, while giving you measurements of 0.1mm of accuracy, or 0.003 inches. A button on the end makes sliding easy, unlocking the caliper’s jaw just when you need it and not otherwise.
When you’re not measuring, you’re probably drawing – which is why the Tiruler packs its own Eternal Pencil into its design. Sitting snugly in a slot thanks to magnets, the pencil can be undocked whenever needed, and used to draw lines, make doodles, annotate documents with measurements, etc. The eternal pencil tip never needs sharpening and can work for decades, while the pencil’s metal body also packs a sharp-ish end that’s perfect for running along the edge of boxes to open them without really being a traditional ‘blade’.
Other rather clever details include the presence of a hex slot for mounting hex bits that turn the Tiruler into a high-torque screwdriver, a spirit level that lets you use the Tiruler to align objects like, say, paintings on a wall, and the mark of a good EDC – a bottle opener that lets you hang loose between serious measuring jobs. Maybe not the best feature for a ruler you’d pass down to your kid, but hey, the Tiruler is versatile EDC first and heirloom-material later. Finally, tritium slots really cement the EDC status of the Tiruler, making it the perfect collector-item for anyone who loves gear and multitools.
The choice of titanium for the Tiruler’s construction gives it the power of true longevity. Beyond its obvious resistance to bending (the death knell for lesser rulers), titanium offers corrosion resistance that ensures this tool will age gracefully through years of workshop abuse and pocket carry. The overall device weighs a paltry 60 grams or 2.1 ounces, and the lack of a blade makes the Tiruler TSA-friendly, so you can easily carry it with you wherever you go – whether it’s to work or even on a flight. Now I don’t normally need a ruler or protractor on flights, but hey, you do you?
What impresses most isn’t just the number of functions MakerPi has packed into the Tiruler, but how harmoniously they coexist. Each capability occupies its dedicated space without encroaching on the others, resulting in a tool that performs each task with surprising competence. The Tiruler starts at $89 (surprisingly affordable for a titanium-based multitool), which includes the ruler itself, the eternal pencil, and also a cowhide leather holder for your tool, giving you something that’s truly upper-echelon. I swear, if I had this as a child I’d be the coolest kid in math class.
