The SOG Trident uses our well-proven means of delivering a knife blade to the open position with 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 Groove™ in the handle, which allows the operator to cut paracord, fishing line, , etc. without having to open the blade. The handle also includes a Digi-Grip™ variable pattern for coarser grip in areas that require it. Our bayonet style clip is easily switched for right/left hand carry or removed for pouch storage.
