Hey there, adventurers of creativity and precision! 

I’m excited to introduce you to the Prule – a truly revolutionary titanium folding ruler that brings together practicality, adaptability, and functionality in a way you’ve never seen before. It’s not just a ruler; it’s a game-changer.

Made from Gr5 titanium, Prule is a tough little ruler that’s built to last. It folds up magnetically, making it super easy to carry around with you. Despite its compact size, Prule is incredibly strong and durable, making it perfect for a wide range of tasks. Also, the Prule has made significant improvements in its ergonomic design. 

But here’s the real kicker: a built-in protractor for measuring angles and a tiny craft knife for quick cuts or trimming. Of course, the Prule packed with more features that make it even more versatile. Whether you’re working on a DIY project, doing some crafting, or just need a reliable ruler for everyday tasks, the Prule has everything you need in one sleek, ergonomic design.

So why settle for an ordinary ruler when you can have the Prule? It’s the perfect addition to your toolkit, ready to tackle any task you throw at it. It’s tailor-made for DIY enthusiasts, crafters, students, architects, engineers, and for anyone who values accuracy and comfort. 

The Prule is crafted with a 25° angled surface that naturally aligns with your line of sight. This means you can read the measurements without straining your neck or back, making reading measurements a joy, not a chore.

Comfort to read

With its unique thickened design, the Prule is not only easier to grip, but also ensures safer cutting by keeping hands away from the path of the blade, providing a more stable and safe measurement state.

Alright, let’s talk about the material now. The Prule is made from Gr5 titanium, which is super strong and lightweight, perfect for high-performance tasks. Its incredible strength ensures it won’t break easily, giving you peace of mind. Despite being tough, it’s so light you’ll barely feel it in your pocket, and it looks awesome too. The titanium body makes it durable and versatile, performing flawlessly in any environment. Built to last, the Prule withstands the toughest conditions without compromising performance, making it your perfect go-to tool.

Imagine a ruler where every mark is as crisp as a freshly pressed button. Our laser-etched scales provide unparalleled clarity, ensuring you never miss a millimeter or a sixteenth of an inch. Whether you’re working in imperial or metric, the scales are meticulously engraved to provide accurate and easy-to-read measurements.

Tired of guesswork when measuring from a non-zero starting point? Our ruler starts its scales at zero, providing an intuitive and straightforward measuring experience. No more subtracting or estimating – just clear, accurate measurements every time.

Meet the ruler that adapts to your needs. Its design allows for both deep and shallow measurements, making it perfect for a wide range of tasks. Whether you’re measuring the depth of a wide, deep container or the narrow confines of a tiny bottle, this ruler is your versatile, reliable companion.

The Prule cleverly turns its folding design into a super-versatile protractor that both pros and hobbyists will love. We’ve really put some thought into the ruler’s hinge, making it double as a protractor that smoothly opens up to 180 degrees. With this innovative design, you can measure any angle in a breeze, just by using the ruler’s natural motion.

Inside this range, we’ve thoughtfully added six different detent spots, each marked every 30 degrees. These spots give you a nice clicky feeling when you hit them, helping you set common angles quickly and accurately. Whether you’re sketching cool designs, planning out buildings, or doing detailed engineering work, the Prule is incredibly handy. You can easily lock into the angle you need, making your measurements and drawings both precise and quick.

But The Prule doesn’t just measure – it cuts too! Our ruler is equipped with a hidden blade that’s perfect for a wide range of cutting tasks.

• Safely Hidden in a Groove: The blade is cleverly concealed within a groove, keeping it out of harm’s way when not in use. This design ensures safety and prevents accidental injuries.

• Magnetic Connection for Security: Worried about the blade falling out? Don’t be! It’s magnetically secured, ensuring it stays put during transport and use.

• Thumb Groove for Easy Access: Say goodbye to fumbling around! The thumb groove is strategically placed to make retrieving the blade a breeze. 

• Compatibility with #11 Surgical Blades: These blades are renowned for their sharpness and versatility, capable of cutting through a wide range of materials including paper, leather, ropes, labels, and even pencils.

• Quick-Release Head for Blade Replacement: Need a fresh blade? Our quick-release head design allows for easy and hassle-free blade changes. Simply press the release button, slide out the old blade, and insert a new one. It’s as simple as that!

Attach a rope or lanyard to the convenient hole, making it easy to keep The Prule with you wherever you go.

A ceramic bead breaker is included for emergencies, and the tritium slot allows you to insert a tritium or glow tube, making Prule glow in the dark for easy location. In emergency situations, the ceramic bead can be used to break windows, providing a vital escape route.

Equipped with 2 tritium slots on each side, you can insert 1.5*6mm tritium tubes or glow-in-the-dark tubes for easy location in dim environments. This feature ensures that The Prule is always within reach when you need it most.

The journey of the Prule, from initial concept to prototype, and now to a final product, has taken us over half a year of hard work and dedication. If the product is well-received and supported by everyone, it will take a few more months from production to shipping before it reaches your hands. We are aiming to start shipping by the end of March, and while we will do our best to deliver earlier without compromising on quality, we will also keep you updated throughout the entire process.

Of course, the design process of The Prule was not without its challenges. Initially, our goal was simple: to create a folding ruler. But how could we make it more innovative and unique? We pondered over this question and came up with an idea – using the folding mechanism to create a simple yet precise protractor. By simply adding scales and gears to the ruler, when the concept became true, we thought, “Bang, it worked!”

Here is the initial sketch of the Prule:

With a clear vision in mind, we moved into the design phase. We sketched numerous concepts, refined them through CAD modeling, and focused on integrating the folding mechanism with the protractor function. Titanium alloy was chosen for its lightweight strength and corrosion resistance, ensuring that the ruler could withstand the rigors of professional use while maintaining a sleek and elegant appearance.

With the help of 3D printing technology, we created multiple prototypes for physical testing and functional verification. User feedback was invaluable, guiding us to make further improvements. We iterated on the design, optimizing ergonomics, aesthetics, and the overall user experience.

Eventually, after numerous rounds of testing and refinement, we successfully crafted a final prototype that embodied our vision. The Prule Titanium Multi-Functional Folding Ruler not only folded for easy storage but also featured a precision protractor with scales and gears, making it a versatile tool for professionals across various fields.
