The Trident uses our well-proven means of delivering its AUS-8 steel knife blade to the open position with one hand using S.A.T. (SOG Assisted Technology). Now using our patent pending Arc-Actuator, the Trident locks stronger and releases easier. There is also a built-in safety to lock the blade closed. When it shows red, you are ready to go. What also makes the Trident so unique is the patent pending slot cutter in the handle, which allows the operator to cut belts, paracord, fishing line, etc. without having to open the blade. The durable glass reinforced handle also includes a Digi-Grip variable pattern for coarser grip in areas that require it. The front of the handle has a built-in glass breaker. Our bayonet style clip is easily switched for right/left hand carry or removed for pouch storage.
