Breaking the Mold, Back to Basics — RU01 ZeroScrew Tech Minimalist Multi-Tool Caliper
Dear Backers,
Have you ever found yourself wondering why tools can’t be both highly functional and beautifully designed? Why can’t we have a product that seamlessly blends practicality with style? These questions have inspired us—the MecArmy team—to push boundaries and create something truly unique.
Today, we’re excited to introduce the RU01, a minimalist, screw-free, multifunctional caliper that redefines what a tool can be.
Sometimes, the simplest needs in life spark the most profound moments of innovation. The creation of the RU01 was inspired by exactly such a moment.
During our daily work, we noticed some undeniable flaws in traditional calipers—they are bulky, complicated, and require constant adjustments during use. We knew it was time for a change, and we set out to make it happen.
We asked ourselves: Could we design a simple yet powerful caliper that doesn’t rely on any screws? With that question in mind, we set out to create the world’s first screw-free caliper.
Through a series of design refinements and rigorous testing, we broke free from traditional constraints and brought the RU01 to life—a caliper that is lightweight yet durable, minimalist yet uncompromising in strength.
The core design philosophy of the RU01 revolves around being screw-free. We want you to feel its uniqueness every time you use it.
The seamless operation, achieved without the need for screws, is not just a design breakthrough—it’s an experience we want to bring to you. With every press, the RU01’s metallic elastic press mechanism delivers an exceptionally smooth and effortless operation.
Free from the clutter of unnecessary screws, the entire process creates a sense of harmony between your fingers and the tool, as if it was naturally meant to work this way. The silky-smooth extension and locking mechanism will leave you thinking, “This is a tool truly designed for me.”
The RU01 is designed to meet a wide range of needs. Whether you’re a professional technician, a DIY enthusiast, or someone who values multifunctionality and portability in tools, the RU01 is your ideal companion for getting the job done.
From daily studies and design work to outdoor activities and even emergency situations, this compact multifunctional tool performs exceptionally well in various settings. With its thoughtfully crafted features and minimalist, portable design, the RU01 becomes an indispensable helper in your everyday life.
Two In One
We designed the RU01 to be simple and efficient, combining a caliper and ruler into one tool. Equipped with dual-scale measurements, it is easy to use and offers versatile functionality.
Safe for Cutting
The RU01 is crafted from a single piece of titanium alloy through CNC cutting, achieving a seamless one-piece design with a thickness of 5mm. This enhances safety during use, especially in cutting applications.
Easy to Grab
Easier to pick up from any surface compared to traditional rulers.
Integrated push-pull design
With a simple press of your thumb and an upward push of the slider, you can easily operate it single-handedly—push with one hand, pull with the other.
We’ve packed all these features into a tool smaller than a credit card. Imagine the convenience of carrying an entire set of tools in your pocket or wallet. Whether you’re a DIY enthusiast, a professional, or someone who likes to be prepared for anything, the RU01 is your reliable everyday companion.
In the world of everyday carry (EDC), convenience and versatility are essential. The RU01 tool provides efficient support for your daily tasks, offering comprehensive solutions for a variety of needs—all through a minimalist design that adds no extra bulk.
From the very first prototype, I’ve carried the RU01 with me wherever I go. Not only does it meet my daily needs, but it also reveals the thoughtful design behind every detail. To me, it’s more than just a tool—it’s a reliable companion I can count on anytime.
The RU01 Tool is crafted from durable Ti-6Al-4V titanium alloy, designed to withstand both everyday use and extreme conditions. Whether submerged in mud or subjected to accidental crushing, its precise construction and strength ensure it remains as good as new, delivering outstanding performance every time.
