Kbar Tdi Investigator W/shth Str

The KA-BAR TDI Investigator fixed blade knife with sheath is a compact, single-edge tactical folder purpose-built for law enforcement, investigative work, and everyday carry by professionals who demand reliability in close-quarters scenarios. Featuring a plain edge drop point blade and fixed configuration, this knife delivers consistent edge retention and zero mechanical failure points—critical attributes for operators and field agents who cannot afford equipment malfunction during critical moments.

The drop point geometry balances blade control with penetration capability, making it effective for tactical applications requiring precision cuts and controlled deployment. At 3.5 inches in blade length and 8.5 inches overall, the TDI Investigator maintains a low profile suitable for duty carry, evidence collection, and training scenarios where blade length is regulated or constrained. The fixed blade design—devoid of folding joints and springs—ensures the knife performs identically whether deployed from a holster in warm conditions or after extended storage in a duty locker. The included straight sheath accommodates rapid draw while maintaining positive retention.

This model is engineered for investigators, tactical personnel, and law enforcement professionals who prioritize simplicity and dependability over folding mechanisms. Plain edge blades excel in cutting tasks where edge geometry matters more than serration—from cutting paracord during training to controlled cuts during evidence handling. The 0.44-pound weight allows extended carry without fatigue, and the compact profile fits duty belts, ankle rigs, and appendix carry systems. KA-BAR's manufacturing heritage ensures the TDI Investigator meets the durability standards expected in field-tested tactical equipment.
