MilGear: SOG Trident Folding Knife

by  •  Sep 20, 2012

Trident Folder from SOG

The Trident – Black TiNi folding knife by SOG is a general purpose folding knife that is comfortable for every day wear/use at home or in your military kit while out in the field.

When it comes to the military, one tool has been around longer than any other, the knife. Military men and women have learned that a good knife can save your life, assist a mission or just help with your day to day work. As a former parachute rigger, our job required that a good reliable (aka sharp) knife was at the ready at all times which means you learn quickly to appreciate a knife that is easy to carry, use and hold an edge.

Recently I spoke with representatives of SOG Knives and after talking to them about our audience they were happy to send over some product to review for our audience here at Off Duty Gamers. In the end they sent three knives but the Trident folder has become the daily carry I won’t leave the house without.

Manufacturer Description

The SOG Trident uses our well-proven means of delivering a knife blade to the open position with S.A.T. (SOG Assisted Technology™) Now using our 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.

Ease of Use

This knife is has a good weight, not heavy when you carry from day to day but solid enough to handle the job. This knife features the SOG SAT system (SOG Assisted Technology) which allow for users to open the knife easily using either your primary or off-hand. When you use the thumb nub on either side of the blade, the assist spring takes over when you break approximately 15 degrees of opening. The assist function is tight and smooth but by no means is it an automatic open. While you are still opening the knife with your thumb movement your effort decreases as the blade swings open and locks into place firmly.

S.A.T. Defined

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).

We warn you… this blade action is addictive! Play with it once, and you’ll be opening it again and again!


For my money the folding knife is something everyone should own and carry. There are so many times when a good sharp knife can get a job done long before you can find a knife or scissors elsewhere and for this point it has to be easy to carry.

The Trident Black TiNi is a good size which fits neatly into a pocket, in my case it sits in my front jeans pocket with the rear clip securing it in place. The clip is lose enough that simply moving the body of the knife into my pocket will catch the clip and seat itself. Standing or sitting, this knife is comfortable.

The handle features a grove that when the knife is closed can be used for cutting paracord and line, string etc without ever opening the knife. The knife features a safety so you can engage it to use the groove without pushing the knife open. This also acts as a great secondary safety to keep the knife closed during transport in your bag or even your pocket.


I’m no longer in the military but a good knife is still something I keep close. I work with paracord all the time and this knife stays sharp through all the nylon and plastic and hasnt flinched at any job around the house it was needed. I am by no means hard on a knife so I went out looking for someone who might be. I was shocked to find out that two of the staff members here at Off Duty Gamers actually carry Trident folders as the day to day military use knife. They had purchased these for themselves and both were very happy with the purchases.

EODTech – US Army Explosive Ordinance Disposal

I love this knife. I want to marry it. I’ve carried it with me everywhere I’ve gone, including smuggling it through airports, for over two years now. (Note to DHS: only in foreign airports. No need to come after me. Not for THAT reason, at least.)

I like that it is pressure assisted so I can get the blade out one-handed (techs often need to keep one hand on whatever we’re defusing at the moment), and I like that there’s a blade lock so that I don’t accidentally open it inside my pocket and stab myself. As someone who fidgets incessantly in boring meetings (maybe I shouldn’t have gone the officer route, but hey, recruiters lie to us too, guys) I often play with my knife in my pocket, so the safety is nice. And there’s another positive block to stop the blade from retracting before you’re ready. I like this too.

As somebody who’s had to pull bodies out of vehicles because the soldiers couldn’t get their seatbelts off fast enough, I also am obsessed with carrying a strap cutter with me everywhere I go. I love that the Trident has a built-in strap cutter—that means one less tool I have to carry, so now I’m down to just the knife and my tourniquet (yes, even in civilian clothes….PTSD is awesome, boys and girls).

I like the heft and texture of the handle, and the balance of the entire tool unfolded. It’s got a hole on the aft end for your dummy cord and the belt clip makes it easy to fit in a pocket or on a belt. I wrapped the clip with pink duct tape so nobody would steal it. (Pro Tip, dear friends: if you paint, tape or color your things pink, nobody will steal them and you can tell across the gym which pair of shades or water bottle is yours.)

I’ve used this tool for everything you can imagine. Hand entries, digging, cutting and molding C4, even as a makeshift det cord cutter and screwdriver. I scraped the black finish off the tip of the blade digging live grenades (a LOT of them, that incident took over six hours) out of the ground over near the new 108 ADA Brigade HQ at Ft. Bragg. A couple days later I used it to cut my A-ration sausages out on a field problem and it worked fine. (Note: be sure to clean your blade properly before using it to cut food. C4 residue gives you awful diarrhea and nitroglycerine residue gives you the worst migraine you’ve ever had. I’m not making any of that up.)

I’ve never had to sharpen or oil the Trident, and my proactive (and awesome) wife often washes my pants and forgets to take it out of my pocket. Even after a half dozen washes, the Trident still unfolds and closes just like the day I got it.

I’m no expert, and I’m sure a lot of techs or servicemembers in general have their own favorites. But unless somebody makes a knife with all of this tool’s features and figures out a way to make it do my taxes for me, I’m sticking with the SOG Trident. You should get one, and recommend it for your unit’s next CONOPs pre-deployment purchase. (Another Pro Tip: calling it an “access tool” on the purchase request will often get it past the S4s and XOs who just love to shoot down requests for things that soldiers actually, you know, need.)

I love the utility and build quality of my Trident. Always get compliments at work. The feel of the grip suits me well. And I’ve been using it for duty ever since

The bottom line here is that if this knife serves well in heavy as well as light use situations making it a great all around at home or on the job tool.


If you haven’t already figured it out, this is a high quality durable piece of equipment. The parts are well designed, the action tight and reliable and the knife is assembled with care right here in the United States.

The blade is where the rubber meets the road and SOG has worked hard to bring us a cutting surface that retains an edge for longer periods of time while maintaining a strong knife that resists breaking through its 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 -300°F 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.


Any knife that is comfortable, keeps an edge and can be used in multiple situations is a valued piece of equipment. The Trident folding knife absolutely fits that description. The knife can be found for around $100 (plus or minus $30 we’ve found online) and is worth every penny. Sharp, dependable, easy to use and able to take the day to day wear from white collar general use to military field beating.

Final Word

If you don’t have a knife and are looking for one, check out the SOG Trident, if you have one and are looking to upgrade or replace then here’s one that should be on your short list. Three members of ODG now carrying this knife in very different usage should say a lot about a knife’s ability to cover a lot of ground reliably.
