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.

Newly introduced are the single hand opening, non-automatic, ambidextrous, TDI Folding Knives. These low profile knives are easily concealed, lightweight and there to meet your specific law enforcement needs. Each folder comes with a reversible pocket clip so it is always where you need it to be.
