The Flash family of knives feature SOG Assisted Technology (S.A.T.) which employs a powerful piston lock that is easily released with a sliding button. SOG also had the foresight to incorporate an additional safety lock that gives added security when the blade is closed. Note that when the safety shows red...YOU ARE READY TO GO!
