The United Cutlery Undercover Sabotage Spike Knife is especially designed for hand-to-hand combat. The Undercover Sabotage features a tanto dagger AUS-6 blade with a baked on blade that is 1/5" thick and incredibly strong. It won't break or bend like cheap imitations. The double-edge blade is razor-sharp and performs equally well at stabbing and slashing. The slim-profile allows it to be worn on the wrist or on the back of the belt using the included nylon wrist sheath.
