N.U.M.B. Knifeworks N1 Conerstone

The N1 Cornerstone is more than a debut—it's a declaration. As the first knife from N.U.M.B. (Nick’s Unhinged Mechanical Brain) Knifeworks, the N1 marks a bold entry into the world of blade design. Known for his broad creative output and mechanical curiosity, Nick brings his distinctive design language to life in collaboration with the precision manufacturing of Reate Knives.

At the heart of the N1 Cornerstone lies the PinchLOK mechanism—a unique ambidextrous lock system built around two detent balls and dual locking arms. This configuration delivers secure, confident lockup while offering a satisfying and intuitive user experience, whether right- or left-handed.

Every detail of the N1 reflects Nick’s methodical approach to design: from the milled titanium handle with subtle geometric contouring, to the modified sheepsfoot blade that balances cutting power with control. A reversible titanium pocket clip rounds out the carry options, ensuring the N1 stays close and ready, no matter the setup.

The N1 Cornerstone sets the tone for what’s to come from N.U.M.B. Knifeworks. A fusion of engineering curiosity, tactile awareness, and design that invites engagement—it’s not just a starting point, it’s a signal of direction.
