The Ka-Bar Original TDI knife (Ka-Bar part no. 1477CB) is a compact, low-profile fixed blade designed by John Benner, founder and owner of Tactical Defense Institute. It was conceived as a last option knife for close-quarter encounters, and worn on the belt the knife and sheath stay well concealed. The partially serrated edge cuts looped and synthetic materials, and the handle scales and sheath are coyote brown. A hard plastic sheath and a reversible black metal belt clip come with it. The TDI is built for law enforcement, military and security users who need a small knife that draws quickly.
