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.

Product Description

SOG Trident Tanto Folder Knife. Deploys in a blink of an eye! TheTrident uses SOG's well-proven means of delivering a knife blade to the open position 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. 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. Cryogenic Heat Treatment SOG's unique cryogenic heat treatment process increases the toughness and wear resistance of our blades. Taking the knife slowly down in temperature to less than -300F and then back to room temperature. This stress relieves the material on an atomic level and increases overall strength as well as edge retention. Knife edges stay sharp longer with significantly less micro-fracturing and edge-chipping. Its this dedication to making your knife SOG sharp that sets us apart from the rest. SOG Assisted Technology SOG Assisted Technology works through the balance of opposing high-tension coil springs. As one opens the blade the force to propel the knife open becomes greater than the closing force and the blade will open on its own. The end result propels the blade out once the operator has initiated the one-handed opening action. S.A.T. works so well that right-handers can use their left hand equally well to open a folding knife (of course this works oppositely for lefties). More: Blade length: 3 3/4 x 1/8"; Overall length: 8 1/2"; Weight: 3.6 oz.; Edge: Straight; Steel: AUS 8; HRC: 57-58; Handle: Zytel wtih Groove; Finish: Black TiNi; Assembled in the USA.

The pros and cons kind of balance themselves out so I'll just say my thoughts in broken sentences.

-Handle- is strong...like Kansas! Feels weak because of the lightness--but the thing just won't scratch or crack...dropped it 40ft off a balcony on accident...no mark. Handle is a single piece of Zytel(a nylon base with glass reinforcements, DuPont invented it to be near indestructible and still be lightweight) with steel skeleton reinforcements, sturdy, but hard to clean the debris out. Best grip I've had on a folder. It's no Ka-Bar USMC, but the grip works well for multiple holding styles (from an extension hold to an icepick).

-Blade- American Tanto style. Not the Cold Steel chisel grind. This one actually keeps an edge and the straightness makes working it on a flat stone pretty easy. They'll say things like "double grind". Lamens Terms--The body(belly) of the blade is a hollow grind(curves like a parabola to a super sharp edge on both sides)to a straight grind on the tip (Not as sharp, but just about the strongest grind). This means you get a good cutting edge and a strong tip. The tip is also a drop point, so it feels a little more natural for tip control. The major drawbacks on this blade is it's strengths. The beefy blade and reinforced spine of the tanto tip means it could withstand a beating, but it's a little thick on the profile...and heavy for the Spring.

-Overall- Great knife, still the one I have in my pocket everyday. The tanto blade isn't as lightning fast as the large-bellied thin profiled clip-tip standardized with the SOG Trident, but I'm more about durability.
And the suggested retail price of the TiNi coated Trident Tanto is about $100. I think it's $108 on the official site as of 4-11-07. So if it's under $70, it's a steal.

5.0 out of 5 stars Great Knife, Quality Feel, January 7, 2010

This review is from: SOG Specialty Knives & Tools TF-7 Trident Tanto, Black TiNi (Tools & Home Improvement)

Purchased the SOG TF-7 Trident Tanto as a Christmas present for a family member. I considered Benchmade, Kershaw, Microtech, and CRKT. Most were very expensive compared to SOG. Was very pleased with the knife. It's a really good looking knife. Solid quality feel when in your hand, textured grip. If you have larger hands this knife fits perfectly. Opens very fast with the assist, and rock solid locking feature. Parts function very smooth, no rattles or gritty feel. The line cutting mechanism is a good add-on, especially if you're into fishing. Extremely sharp, makes cutting very quick and effortless. Has the tanto edge, black. No complaints at all. There are a few good youtube reviews as well, just google SOG Trident.

This knife is great for anyone out there. It's especially handy if you are in the emergency (Police, EMS, AFD, or military) but I think everyone should have one at all times.
