Designed by John Benner, founder of Tactical Defense Institute and a former cop, the TDI Law Enforcement Knife from Ka-Bar was created with law enforcement in mind. The knife is meant to be worn at the off hand and draws like a pistol. If an officer finds himself in close quarters with a suspect attempting to take his handgun, the TDI knife can be available as a last-defense option. Coupled with an ambidextrous, hard plastic friction sheath, the unit is easily mounted on an officer’s pants belt and concealed behind gear on a duty belt.
