The Trident TF1-CP Folding Knife uses SOG's well-proven means of delivering a knife blade to the open positions with S.A.T. (SOG Assisted Technology). Now using their 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! Equipped with the unique, 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-Frip variable pattern for coarser grip in areas that require it. SOG's bayonet style clip is easily switched for right- and left-handed carrying or removed for pouch storage. Manufacturer Lifetime Warranty.
