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 as an "off hand" knife that draws like a pistol, the reversible hard plastic friction sheath can be worn on either the right or left side. Features a non-reflective black powder coated serrated blade and a textured Zytel handle. Includes the Metal Belt Clip for TDI Knives. Designed by John Benner, owner of Tactical Defense Institute.
