The Knife Metal Detectors Can't SEE?!

This terrifying-looking knife isn’t made from steel — it’s made from carbon-fiber composite. Carbon-fiber shivs and spikes can be extremely lightweight, rigid, and largely non-metallic, which creates an obvious problem for security systems designed primarily around detecting metal. But being non-metallic doesn’t make a weapon invisible. Modern airports combine multiple layers of security, including X-ray systems and body scanners, specifically because dangerous objects aren’t always made from steel. And unlike an old Samsung phone, dropping this isn’t supposed to launch the battery across the room. 😭 The result is a strange battle between modern materials and modern detection technology. #carbonfiber #knife #weapons #technology #airportsecurity #science #facts #militaryfacts #shorts Disclaimer This video is intended for educational and informational purposes only.
