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. Blade: 3.75" Overall: 8.5" Weight 3.6 oz.
