In extreme close quarters encounters where a suspect is attempting to take an officer's handgun, or an officer cannot access his handgun, the TDI knife is available as a "last option" knife. When worn on the pant belt the entire unit – knife and sheath – is well concealed. Designed by John Benner, founder and owner of Tactical Defense Institute. This knife has a black coated blade, black handle and sheath, and black metal belt clip.

+ Black drop point blade made from AUS-8A steel.
+ Black contoured Zytel handle.
+ Black sheath for secure carry.
