5 5/8'' overall. 2 3/8'' black powder coated serrated AUS-8A stainless drop point serrated blade. Full tang. Black textured Zytel handles. Black glass filled nylon belt sheath. The TDI Law Enforcement Knife was designed to be used as a ''last option'' knife. In extreme close quarters encounters where a suspect is attempting to take an officer's handgun, or the officer cannot access his/her handgun, the TDI knife is available. Designed as an ''off hand'' knife that draws like a pistol, the reversible sheath can be worn on either the right or left side of the officer's belt.
