Making a quality KA-BAR product requires the talent of experienced craftspeople performing dozens of processes with precision and skill. Each knife undergoes specific manufacturing processes to ensure corrosion resistance, strength, edge holding ability, and an out-of-the-box razor sharp cutting edge. 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 by John Benner, founder and owner of Tactical Defense Institute.
