The SOG Assisted Lock Back knives feature SOG Assisted Technology (S.A.T.) Once the operator has initiated the blade opening action, the S.A.T. propels the blade out and firmly locks it into place. There is an additional safety lock that gives added security when the blade is closed, and acts as an additional lock when the blade is open.
The SOG Lock Back Knives with S.A.T. Assist include the Blink, Twitch, Flash, Aegis, Zoom, Flashback, Trident and many more.
