Equipped with SOG Assisted Technology™, the deployment of the blade is never more than a split-second away. Thanks to patent-pending Arc-Actuator™, the SOG Trident Tanto TF-01 Knife blade locks stronger and releases faster than ever. The built-in safety lock actually shows red when you're ready to deploy the blade. The patent-pending Groove™ in the handle allows the operator to cut paracord or fishing line across the blade while it's still locked. The straight-edge blade is made of strong AUS 8 steel with a hardcased black TiNi finish. The GRN handle features a Digi-Grip™ variable pattern for a confident and controlled grip. Bayonet-style clip included. Assembled in the USA. Blade length: 3.75". Overall length: 8.5". Closed length: 4.75". Weight: 3.6 oz.
