The Story of Impact 127®

"Impact": The result of its radical design.

"127": The weight in grams of the stainless steel version without its sheath.

Though it appears simple, Impact 127® is a masterpiece of ingenious ideas, just like other TB-Outdoor products. Rather than compromising the design for quicker and easier manufacturing, we took the time and made the necessary material investments to create a product without concessions—one that matched our vision.

Impact 127® finds its roots in the history of the first human tools when manufacturing meant removing material rather than transforming it. Early humans carved primitive tools from raw materials, and it is this same pioneering spirit that inspired Impact 127®. This backup knife embodies the core principles of TB-Outdoor’s future creations.

Perfect Center of Gravity

Impact 127® is designed for optimal balance. Its center of gravity is precisely located at the center of the TB logo, around which the knife was designed—like a shockwave spreading outward. This ensures a comfortable grip and uncompromising maneuverability.

More Than a Sheath—An Essential Companion

The Impact 127® sheath is injection-molded under pressure and partially made with glass fibers, making it extremely shock-resistant. Its dynamic, openwork design significantly reduces weight while allowing water to drain naturally. A powerful magnet securely holds the knife in place and guides the blade safely during insertion for maximum security.

The knife and sheath are one. We believe one cannot go without the other. That’s why every Impact 127® knife is sold with this innovative sheath. Secured in its protective case, the blade remains visible while being fully protected.

Premium Materials

Every component of Impact 127® is made from the highest-quality materials, ensuring durability, performance, and resilience. The MOX18Cr steel provides the best balance of cutting quality, edge retention, and corrosion resistance.

To work with cutting-edge materials, you need cutting-edge equipment. TB relies on its fleet of over 100 CNC machines, most of them equipped with 6-axis robots. The production of Impact 127® incorporates the most advanced techniques, including vacuum heat treatment, 5-axis machining, and precision robotics—ensuring that each knife meets the highest industry standards and delivers exceptional quality.
