The Original TDI Knife was designed by John Benner, founder of Tactical Defense Institute. A former Police Lieutenant, Drug Task Force Coordinator, and SWAT Team Tactical Field Commander, Benner has more than 30 years' experience in the law enforcement field. He has developed courses for raid tactics, defensive tactics and knife programs that are currently taught to law enforcement, military and civilian groups.
The TDI/Hinderer knives are design collaborations between Tactical Defense Institute President and Chief Instructor, John Benner, and custom knife maker, Rick Hinderer, owner of Hinderer Knives. Based on their combined respective experiences as a veteran police Lieutenant and Fire Fighter/EMT, John Benner and Rick Hinderer have designed knives for real-world emergency situations - where a sure grip and quick draw are paramount. Features an ambidextrous friction-fit glass reinforced nylon sheath which can be attached at multiple angle to fit anyone's personal preference.
