SOG Assisted Technology Increases Speed, Safety, and Usability
Fast, safe, single-handed opening makes SOG Trident Series knives incredibly easy to handle in a wide variety of situations. When you go to unfold the TF-7’s blade, SOG’s patented S.A.T. (SOG Assisted Technology) takes over. High-tension coil springs propel the blade open, so you can easily access it with just one hand.

S.A.T. knives offer security and peace of mind with their locking mechanisms that are stronger, more reliable, and easier to access than other knives’. For Trident Series knives, this means the blade is held in place with a reliable piston lock that can be quickly released with a sliding button. An additional safety lock offers extra security when the blade is closed, and for easy reference, the lock switch shows red when the knife is ready to be opened.

Cryogenic Heat Treatment and TiNi Coating Guarantee a Sharp, Durable Blade
The TF-7 offers a full, 3.75-inch, AUS8 stainless steel blade that has undergone SOG’s patented Cryogenic Heat Treatment process, which ensures that this blade will stay sharp over the long haul. This intensive process takes more than 48 hours and involves slowly reducing the blade’s temperature to less than -300 degrees Fahrenheit, then slowly heating the blade to room temperature. The stress created by this process strengthens the steel on an atomic level and increases the blade’s overall durability and edge retention.

In addition to having undergone the Cryogenic Heat Treatment Process, this knife is coated in proprietary titanium nitride (TiNi), of the toughest coatings that can be applied to steel. TiNi boasts extreme hardness, is exceptionally scratch and peel resistant, helps increase steel’s longevity, and ensures low reflectivity.

Ergonomic, Lightweight Design Ensures Comfortable Use
Even if your blade is sharp, it’s hard to make precise cuts if your knife doesn’t fit comfortably in your hand. That’s why this knife’s handle is ergonomically contoured. Crafted from tough, glass-reinforced Zytel, the handle is well-balanced and features SOG’s unique Digi-Grip texturing, a feature that gives you gripping power where you need it most. Additionally, the grooved handle allows you to cut heavy cord and cable without having to open the blade.

At just 3.6 ounces, this folding knife is lightweight and easy to carry. A reversible, bayonet-mounted clip extends from the back of the handle, allowing the knife to sit low in your pocket for the most discreet carry possible. The removable clip is easily switched for right/left hand-carry.

This knife is backed by a lifetime warranty that protects against defects in manufacturing and materials.
