Blending elements from the Bowie, Tomcat, SEAL Pup, and Flash Series knives, SOG Specialty Knives and Tools has created a new breed of folding knife: the TF-7 Trident knife with straight blade, tanto edge, and black TiNi coating. Designed for use by Navy SEALs, the TF-7 features SOG's grooved handle, which allows you to cut heavy cord and cable without having to open the specially designed blade. The TF-7's blade is easy to open and features Arc-Actuator technology, which helps the blade lock more strongly and release more easily.


The SOG TF-7 Trident Knife Offers:
  • A straight blade with tanto edge and black TiNi coating
  • The ability to cut paracord, fishing line, and more without having to open the blade
  • A strong, reliable blade locking system
  • A contoured, glass-reinforced Zytel handle




S.A.T. propels the blade open for quick, safe, one-handed access. View larger.


The TF-7 features SOG's proprietary Digi-Grip for comfortable, confident handling. View larger.


Cut cords and cables quickly and safely with dedicated Groove technology. View larger.


A reversible clip lets the knife sit securely and discreetly in your pocket. View larger.

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.

About SOG: Strong, Innovative Specialty Tools

SOG Specialty Knives & Tools was founded in the spirit of this elite group and became the first knife manufacturer to offer an expanded line that included fixed blades, folding knives, and multipurpose tools.

Each SOG product is created by company Founder and Chief Engineer, Spencer Frazer. Known for their uncompromising style and performance, these knives and tools showcase innovation, dependability, and a unique, futuristic style that has garnered awards and recognition worldwide. SOG products have also won favor among law enforcement, military, and industrial customers that rely on their tools to perform flawlessly in the toughest, most adverse conditions.

Product Description

The SOG Specialty Knives & Tools TF7-CP Trident is a unique, versatile and fast opening folding knife that provides many different uses, while showcasing SOG’s style and quality construction. Made of AUS-8 steel with an attractive hardcase black TiNi finish, the 3.75-inch straight edge, folding blade has a tanto shape with a very strong tip that's ideal for piercing, sharpens easily and makes quick work of any task. SOG Assisted Technology (S.A.T.) works through the balance of opposing high-tension coil springs. As you initiate the opening action, the force propelling your blade open becomes greater than the force keeping it closed. The result is a blade that springs open instantly once it is engaged, seemingly on its own. The piston locking mechanism uses a movable bar that's wedged between the blade tang and knife handle to lock the blade in place while in the open position. The ergonomically contoured and well-balanced handle has a black finish and is made of a high strength, abrasion and impact resistant glass-reinforced nylon that will fit comfortably in your hand. The Digi-Grip variable pattern provides a secure, no-slip grip and the base of the handle sports a groove that allows the user to cut paracord, fishing line and other cord-sized objects without having to open the blade. The reversible belt clip provides a low and discrete carry for right and left handed users or can be removed for pouch storage. The TF7-CP has a closed length of 4.75-inches, overall length of 8.5-inches, blade thickness of 0.13-inches and weighs 3.6-ounces. The SOG TF7-CP Trident Knife comes with a limited lifetime warranty. Each SOG product is created with the help of company founder and chief engineer, Spencer Frazer. Known for their uncompromising style and performance, these knives and tools showcase innovation, dependability and a unique, futuristic style that has garnered awards and recognition worldwide.

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.

Style Name: B) Plain Edge
I really like this knife. It has been my EDC for approximately 5 months now and I have many positive things to say about it and only a few negative things. For the purpose of thoroughness I will start from the handle and work my way toward the blade:

1) The Clip: The clip is adequate for what it is designed to do. It holds well in my pocket and rides close to the frame of the knife. It's also ambidextrous, but only with point up carry. The only thing I am not too fond of is how "SOG" is cut out of the metal and not merely etched on the surface. It looks strange, but that's just me.

2) The Rope Cutter: This feature is largely useless on the tanto version of the knife and only works slightly better on the clip point version of the Trident. It works well if you are cutting thin cord or fishing line, but if you are working with anything more substantial it is not likely you can cut through it, and if you can you expend a great deal of energy doing so. This is my biggest problem with this knife.

3) The Safety Switch: This is a safe but annoying feature on the lock side of the knife that is occasionally activated in my pocket, defeating the purpose of carrying an assisted opening knife for speed of deployment. Many people glue their safety switch so that they don't have to worry about this problem. While this is an option, you have to worry about the adhesive creeping into the lock or the assisted opening mechanism, potentially ruining a great knife. Whatever you end up doing, try to create a method that is not so permanent (or just deal with it like I do...it's not that bad).

4) The Lock: The blade locks up fairly well.

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.

My hope is that by posting this I might save someones fingers. The knife itself is a good product in the sense that the blade is plenty sharp and the flat grind gives the edge a nice thin bevel that is easy to sharpen. The AUS 8 is a fine grain steel that is easy to sharpen and gets very sharp with minimal effort. The blade deploys fast and as a light duty cutting tool this knife is great. In reality the handle, overall light wt, and blade thickness indicate that this is a light duty blade and if you use it within these limits and avoid stabbing things and using the knife in ways which might be considered abuse, you run little risk of injuring your fingers. Certainly it beats a swiss army type joint lock or some poorly designed liner locks and button locks in the strength department. The problem is the arc-actuator lock looks like an arc-lock which it is not. The arc-actuator lock is similar to a gerber saf-t-lok and is no stronger. I was able to defeat the lock with about 30-40lbs of upward pressure while the knife tip was stuck in wood. The blade closed on my tripple leather gloved hand and might have caused a serious cut had I not taken the precaution. Of note, the knife did pass the "spine whack" test which many folders have failed. Unlike the arc-lock which can actually stand 1000lbs (reportedly), this lock is much weaker. For fishing, camping and light cutting chores the knife performs well as it is an excellent slicer. There really isn't an everyday use that should cause lock failure, and that's probably why lock failure hasn't been a chronic complaint in other reviews. But if you think you may need to dig, pry, stab with a folding knife for some reason, then get a stronger knife which will have a heavier lock and thicker blade. The only problem is that SOG seems to market these knives as "military" type, hard use folders which I don't see it being.
