Aegis (ee-jis), which in Greek means shield or protection, is also the code name for the worldÂ’s premier integrated air defense system. No wonder we borrowed the name to represent this state of the art line that is filled with technology and features. Start to open the knife, and let Aegis finish the action with a bang, using one of the surest assisted technologies (SAT) out there! Our trademark bayonet reversible clip, built in safety with red/ready to go, checkered DigiGrip handles, and tacky rubber inserts all contribute to make Aegis a platform for todayÂ’s changing world. Cover your back with Aegis outdoor or tactical blades.
