KA-BAR TDI 2490 Flipper Folder: Tactical Precision Meets Everyday Utility

The KA-BAR TDI 2490 Flipper Folder isn’t just back—it’s been reengineered for those who demand reliability without compromise. Measuring 7.3 inches overall, this folding blade is purpose-built for everyday carry, but carries the DNA of a tactical tool. Whether clipped to your pocket, stashed in your pack, or riding backup on your belt, the 2490 is designed to be there when you need it—and invisible when you don’t.

Its 3-inch AUS 8A stainless steel blade offers a sharp balance of edge retention and corrosion resistance, making it ideal for both urban and field environments. The flipper mechanism delivers fast, fluid deployment, while the crossbar lock ensures secure blade retention under pressure. Ergonomics are dialed in with an ambidextrous design, a thumb notch for confident control, and a reversible tip-up pocket clip that adapts to your carry style.

This isn’t a showpiece—it’s a workhorse. Lightweight, responsive, and built to move with you, the TDI Flipper Folder is a modern evolution of KA-BAR’s tactical roots, ready for whatever your day throws at it.

John Benner

Only a 33-year veteran police Lieutenant could truly understand what makes a knife effective for close-quarters defense. While serving as President and Chief Instructor of Tactical Defense Institute, John Benner saw time and time again what he already believed to be true from first-hand experience: In a conflict, fine motor skills deteriorate and gross motor skills are most effective for fending off assailants.

Benner then set out to design a low-profile fixed blade knife for law enforcement, military and security personnel that could be drawn quickly and efficiently in times of duress.

After more than a year of prototype samples and in-field testing, the Benner-approved TDI knife was put into production. The same basic principles that founded that first knife were incorporated into all future TDI models, which now complete an expansive line of tactical knives.
