Compact power for concealed carry

The short, wide blade and ergonomic handle enable rapid draw and a secure grip even in confined spaces—ideal as a backup self-defense tool.

Full Tang construction strength

One-piece steel construction increases durability and reliability under demanding use. Textured scales and screw-fastened mounting add stability and control.

Secure and versatile carry

The molded Kydex sheath with multiple eyelets and a clip allows MOLLE mounting and belt carry. Easy draw with reliable retention.

The KA-BAR TDI Investigator was developed in cooperation with John Benner of the Tactical Defense Institute and is optimized for fast deployment, concealed carry, and work in confined spaces. The Full Tang build ensures high strength, while the Drop Point blade with a hollow grind delivers precise cuts and dependable penetration.

The Zytel (glass-fiber-reinforced nylon) handle provides outstanding resistance to impacts, chemicals, and weather. Fine anti-slip texturing and ergonomic shaping give the user confidence and control even in wet or high-stress environments. The Kydex sheath offers versatile mounting, is MOLLE compatible, and includes a reversible metal clip for comfortable belt carry.
