Aegis (ee-jis), which in Greek means shield or protection, is also the code name for the world's premier integrated air defense system and the sea-based element of the United States Ballistic Missile Defense System. Our comprehensive Aegis line of premier folders is fully integrated with top end systems. Start to open the knife, and let Aegis finish the action with a bang, using one of the surest assisted technologies (S.A.T.) out there! Our trademark bayonet reversible clip, built in safety with red/ready to go, and checkered DigiGrip handles all contribute to make Aegis a platform for today's changing world. Cover your back with Aegis outdoor or tactical blades.
