The KA-BAR TDI Law Enforcement Knife is the original TDI design — a 2.31-inch AUS-8 drop-point blade on a sharply angled Zytel handle that sits flat against the body and draws fast from the waistline. The full-tang build and aggressive grip texture keep it secure in hand.
It’s a dedicated backup and last-line carry knife — carried in its hard sheath low on a belt for a natural cross-draw, compact enough to disappear until it’s needed. The sheath mounts at a range of angles for personal carry preference.
KA-BAR has manufactured knives in Olean, New York since 1898. The TDI line was developed with John Benner of the Tactical Defense Institute, and every knife is backed by a lifetime warranty.
