The Ka-Bar TDI law enforcement knife, serrated (4-1481cp-7), is specifically designed for extreme close-quarter encounters where an officer may need a "last option" knife. It is particularly useful when a suspect is attempting to take an officer's handgun or when the officer cannot access their handgun. The knife can be discreetly worn on the pant belt, as the entire unit - knife and sheath - is well concealed.
