If theres ever a match made in heaven for everyday carry (EDC) enthusiasts, it is undoubtedly the combination of titanium and EDC tools. Titanium, known for its strength and lightweight properties, naturally lends itself to the creation of portable tools that are both durable and functional. Today, many EDC tools are either crafted from titanium or would significantly benefit from its use. Take the realm of stationery, for example. While wooden scales offer a classic touch, plastic scales are budget-friendly, and stainless steel scales are known for their sturdiness, the MecArmy RU01 emerges as a standout. This ruler not only boasts the lightweight and robust attributes of titanium but also cleverly doubles as a set of vernier calipers.

The MecArmy RU01 is a compact EDC ruler designed to fit comfortably on your keychain or seamlessly integrate into your EDC collection. With a length of less than 4 inches and weighing just 1.4 ounces (39 grams), its diminutive size is a key feature that enhances its appeal. Crafted from high-quality titanium, the RU01 is engineered with a two-part design that allows it to function effortlessly as a pair of calipers, providing measurements with an impressive accuracy of 0.2mm.

Designed by MecArmy, the RU01 represents perhaps the most portable form of caliper you can own. Its simplicity is matched by its sophistication; the moving jaw allows users to place objects in between the calipers for precise measurement, accommodating items up to 5cm or 2 inches in length. The etched markings on the scale facilitate measurements in both metric and imperial units, making it versatile. Moreover, when youre not busy measuring small objects, the calipers movement can serve as a delightful fidget toyperfect for keeping your hands occupied during idle moments. Additionally, the straight edge of the RU01 can be used for drawing or cutting straight lines, enhancing its utility.

The design and execution of the RU01 exemplify good craftsmanship. The titanium construction ensures that tolerances are phenomenally low, leading to accurate and durable measurements without any wobble or margin for error. This immaculate build quality means theres little to no risk of the tool falling apart during use. A convenient spring-lock mechanism keeps the jaw closed when not in use, preventing accidental openings and ensuring safe storage. The elegance of the RU01 lies in its hidden details, making it not just a tool but a work of art.

While the RU01s front jaw is not overly sharp, it can serve additional functions such as opening letters or boxes. However, it may not be robust enough for more strenuous tasks, and the absence of an integrated bottle opener could be seen as a missed opportunity. On the back, theres a slot designed for attaching a key ring or a carabiner, allowing you to carry this handy device as an essential part of your EDC collection.

Priced at $79.99, the MecArmy RU01 may seem expensive for a tool that primarily serves one function. Some users might yearn for additional features such as a hex driver or bottle opener to truly enhance its versatility. Nevertheless, when it comes to build quality, there are virtually no complaints. The RU01 stands out as a reliable, robust tool that is always ready for action. Typically, calipers are perceived as fragile instruments due to their sensitivity; however, the RU01 defies this stereotype. It is built to last, potentially suitable for being passed down to future generationsassuming we all have the good fortune to live long enough!
