Unboxer® Marine Nationale

The Unboxer® knife was born from a simple idea. Create a closing, light, very flat knife so that it is discreet, truly efficient, mechanical and clever. It is a real tool whose use quickly becomes addictive and whose Design is in direct continuity with other TB Outdoor products. The manufacture of the Unboxer® is 100% French, carried out by a motivated team who are proud of their company's products.

The unique operation of the UNBOXER® lies in the innovative design of its blade. The complex cutting of the heel of the blade, associated with the precise positioning of a fixed pin ensures the function of the absent spring. In the closed position, the blade is held firmly in the handle to ensure maximum safety. In the open position, the blade is blocked by an integrated forced catch system. As the blade is not locked, it simply closes by applying pressure as when using a classic pocket knife. This mechanism eliminates the need for side plates and the spring. The substantial weight saving saves more than a third of the total weight of the same product in a conventional design. It required a large number of tests and validation to obtain optimal operation.

Mr. Yves NEVEUX, well known to pocket knife enthusiasts for the ingenuity of his mechanisms, is at the origin of this reflection. He actively participated in the development of the UNBOXER® and its development. The resistance of the mechanics has been tested in real conditions and in the laboratory. We have tested the blade opening and closing on a test bench over 100,000 times. At the end of this test and days of patience, we found that the knife worked just as well as when it was first opened. The Unboxer® is designed to last!

The choice of materials is one of the keys to the success of the Unboxer®. First of all, the blade is made of high performance stainless steel. Nitrox® is a so-called “nitrogen-doped” steel. The introduction of nitrogen during its formulation makes it possible to replace part of the carbon for better corrosion resistance while maintaining very high level cutting capabilities. The handle is made of polymer loaded with injected glass fibers. The very high resistance of this material allows the knife to maintain reassuring rigidity on all occasions. All the screw parts were manufactured in stainless steel by TB OUTDOOR specifically for this knife.

Discover Unboxer®, the lightweight, mechanical and flat closing knife, manufactured with expertise in our workshops in Thiers. Designed to be worn with extreme discretion, Unboxer® stands out for its unique operation based on an astonishing blade design. This ingenious mechanism frees itself from traditional springs and plates to achieve minimal weight. The blade is held securely in the open and closed position.
The mechanics of Unboxer® were subjected to rigorous tests on our test benches, where it passed the test of 100,000 opening and closing cycles without problem.

Another innovation of Unboxer® is its removable clip, which can be installed or removed without the use of tools. A simple pressure between your thumb and index finger allows you to position it on the right or left of the handle, depending on your preferences.

In addition, Unboxer® is equipped with a clamping system at the blade axis. The blade axle screw allows you to adjust the force required for opening and closing. Thanks to the anti-rotation screw housed in the notches of the axis, your adjustment will remain constant over time.

With a weight of only 54g, a blade length of 72mm and a total length of 110mm in the closed position, Unboxer® offers excellent portability and fits easily into your pocket or bag.

Whether you're an outdoor adventure enthusiast, a DIYer, or an everyday user, Unboxer® is designed to meet your expectations for practicality, reliability, and discretion. Experience versatility and innovation with Unboxer®, the closing knife that pushes the limits of lightness and functionality without the slightest concession on mechanical qualities or finishes.
