Do you recall the most impressive geometry set you ever encountered during your school years? Perhaps it was a treasured possession, an object of envy belonging to a classmate, or a fanciful item you longed for while browsing through a store. Now, envision all that nostalgic coolness consolidated into a single, extraordinary instrument. That's exactly the sensation I experienced when I first laid eyes on the Tiruler—a delightful fusion of awe, excitement, and an irresistible urge to possess it.

The Tiruler, developed by the innovative engineering team at MakerPi, marks a remarkable shift into the realm of tangible and practical everyday carry (EDC) tools. Unlike any other tool I have encountered, it boasts over ten distinct functions, each seamlessly integrated into its sleek design. This device not only serves as a measuring tool but does so with an exhilarating industrial-steampunk aesthetic that conveys both its serious utility and its design sophistication. The exposed mechanics and dual-material structure are not merely for show; they communicate the tool’s purpose while celebrating its functional essence.

As you explore the capabilities of the Tiruler, you’ll quickly appreciate how much it packs into its compact form factor. When fully closed, the device measures approximately 120mm (4.7 inches) and expands to a generous 200mm (7.8 inches) scale when opened, perfectly catering to various measuring needs. Crafted entirely from titanium and featuring etched numerals, the Tiruler is designed for durability, allowing it to withstand extensive use while maintaining accuracy. It incorporates both imperial and metric scales and features an innovative pivot that acts as a protractor, which is particularly useful for drawing or measuring angles.

One of the standout features is the brass enclosure on the pivot, which is engraved with degrees, allowing users to effortlessly create or measure angles. While I once owned a plastic scale/ruler that attempted to provide similar functionality in school, it succumbed to inaccuracies and wear over time. In contrast, the precision machining of the Tiruler ensures exceptional accuracy—even to the minutest detail. Also, embedded within the tool is a functional vernier caliper, a feature that sets the Tiruler apart from typical measuring devices.

Alongside the pivot is a rolling scale that enables users to measure non-linear surfaces easily. This feature is perfect for curves or for taking measurements in situations where a standard scale won’t suffice. The rolling scale clicks with each complete revolution, simplifying the process of tracking measurements. This innovative system allows users to continue measuring indefinitely—just count the clicks and read the final number on the roller to determine the overall measurement.

For more intricate measuring tasks, the integrated vernier caliper emerges from its slot in the Tiruler, extending up to 50mm and offering precision measurements to 0.1mm (or 0.003 inches). A conveniently placed button facilitates easy access to the caliper's jaw, allowing users to unlock it whenever necessary.

When it comes to drawing, the Tiruler features an innovative Eternal Pencil, which fits snugly in a magnetic slot. This allows for quick access whenever you need to sketch lines, annotate documents, or doodle. The pencil's unique tip requires no sharpening and can last for decades, while its metal body is designed with a sharp edge that can be used to open boxes without needing a traditional blade.

Moreover, the Tiruler includes a hex slot for attaching hex bits, transforming it into a high-torque screwdriver, along with a spirit level to ensure perfect alignment for tasks like hanging artwork. Additionally, a bottle opener is discreetly integrated into its design, adding to the tool’s versatility and appeal for various everyday scenarios. While the bottle opener may not be the quintessential feature you’d want to pass down to your children, it exemplifies the Tiruler’s EDC-first mentality.

The choice of titanium as the primary material for the Tiruler is noteworthy as well. This lightweight yet incredibly strong metal renders the tool resistant to bending and corrosion, ensuring that it can withstand years of rigorous use, whether it’s in a workshop or carried in your pocket. Weighing in at just 60 grams (2.1 ounces), the Tiruler is also TSA-friendly, making it easy to take with you on flights or to work. While I may not regularly require a ruler or protractor when traveling by air, the convenience of having such a compact tool at my disposal is certainly a plus.

What truly impresses me about the Tiruler is not just the multitude of functions it offers but how seamlessly they come together. Each feature occupies its designated space without interfering with others, resulting in a tool that performs each task with unexpected competence. Starting at a modest price of $89—especially reasonable for a titanium multitool—the Tiruler comes complete with the measuring tool itself, the Eternal Pencil, and a premium cowhide leather holder, elevating it to a truly luxurious level. I can’t help but think that if I had this tool as a child, I would have undoubtedly been the envy of my math class.
