ABOUT SOG

Our story begins in Vietnam, where members of a highly classified US special ops unit - known as MACV-SOG - carried a unique combat knife into the jungle on covert missions.
Years later, in 1986, that knife inspired a young designer, named Spencer Frazer, to found SOG Specialty Knives.
His mission: to reproduce the original SOG Bowie knife and pay tribute to the special ops unit that created it.
What began as a single commemorative model soon became a full line of innovative tools - field-proven by US Special Forces, even honored as the Navy SEAL knife of choice.
Today, SOG knives are carried with confidence into the most demanding situations. Forged out of tradition, hardened in the field, honed for you.

5.0 out of 5 stars Solid, Large and Sharp EDC/Vehicle Knife
Reviewed in the United States on March 21, 2024
Color: Black/RedVerified Purchase
The media could not be loaded.
 As a long time EDC of SOG Flash Tanto, this upgraded version of the SOG assisted open pocket is excellent. Everything about it is large for an EDC. But since I lost one of my original Flash Tantos due to an unplanned emergency commercial flight, I wanted to replace it with another SOG with other options. This Trident is very snappy on the open and smooth on the close. I can easily open/close one-handed. The unlock slide is low profile compared to Flash. It took a few minutes to get the feel of it but it feels natural. My Flash may be a bit high profile actually. The D2 cryo blade has a beautiful drop point geometry and will function well as both a slicer and poker. Absolutely no lateral play on the nicely centered blade hinge. Great lockup both open and closed with safety on. The safety location is unique to me like a Mossberg shotgun on top vs. side slider but plays well with the ambidextrous design. Edge is razor sharp and has a great polished bevel with no defects. I will strap this in my car for emergency use for me or rescue of another trapped motorist since it has dual glass breaker points and a seatbelt/line cutter. Not sure how well that feature will work with modern seatbelts though. Out off the box, I’m very happy with the purchase and is a decent value in today’s dollars for the quality of components, fit and finish. Recommended for anyone who is familiar with these types of knives and/or wants a good sized one like this. I like the look too, fwiw. ;)

All things considered this is a very nice knife for the money. The fit, finish and quality is spot-on, and it opens with lightning speed and the lockup is secure. I personally prefer Cold Steel knives, but you will not go wrong with this SOG.

5.0 out of 5 stars great knife
Reviewed in the United States on March 18, 2022
Color: Black/RedVerified Purchase
Great knife and looks slick with the red accents. My only criticism is that unlike previous generations of the Trident the back is open which allows lint and stuff to more easily collect inside and I think doesn't look quite as cool.

The knife arrived with a really tight action and required too much force for me to open comfortably, so I loosened it with a Torx bit until I was happy with it. I saw one review where the person talked about flipping the knife open and closed for hours and hours and laughed, it definitely was uncomfortably stiff for me as well. I've owned a number of SOG Tridents and they last long enough that at some point you'll likely want to pop it open anyway for a deep clean.

2.0 out of 5 stars Design flaws
Reviewed in the United States on October 27, 2022
Color: Olive DrabVerified Purchase
I have been caring this knife everyday for about a month and a half. It has some of my favorite features and Lease feet favorite combined into one knife. Starting with the things I like, the blade geometry is excellent, but that's maybe just personal preference. Edge retention is about what you would expect for a knife in this price point. No complaints.

The handle is very comfortable. The stippling is aggressive, but feels almost too sticky. I have had some trouble adjusting my grip to close the knife and did manage to catch the end of my finger in the blade causing a pretty decent slice.

The spring assist is very positive, almost violent. I have had the knife open in my pocket on two occasions. Leading to getting stabbed while trying to fish my wallet out of the same pocket. The thumb studs on the blade are large and easy to manipulate even while wearing gloves, but I believe they snagged on something and the blade assist did the rest. It's almost like SOG was aware of this issue so they put a blade lock, but that also has given me issues when the blade doesn't open when I want it to only to realize the blade lock got bumped on.

But by far the most frustrating feature is the strap cutter slot. It is right at the base of the pocket clip and gets hung up on my pocket every time I try put the knife away. I developed a technique where I would lay my index along the back of the knife preventing my pants from Catching in the slot and pushing away from my body to direct the clip into place. But the aggressive stippling makes this difficult.
In summary my work requires that I'm climbing in and out of different pieces of equipment a dozen times a day and often working in small spaces. I no longer feel safe carrying this knife in my pocket at work. Not really sure what SOG was thinking here.

4.0 out of 5 stars Nice replacement
Reviewed in the United States on September 4, 2023
Color: BlackoutVerified Purchase
I carried the SOG flash II tonto blade for the last 5 years but haven’t been able to keep a reliable edge after so much use. This is a nice upgraded replacement for a left handed person.

Fortunately I have less to worry about while putting this in my pocket that the right handed folks, but it would be great to get an option (without) or cover for the seatbelt cutter because it can slice your pants very easily.

I sanded down the handle texture below the pocket clip so it will slide easily into my pants, but beyond that- no complaints!!!

4.0 out of 5 stars Blade deployment lacking
Reviewed in the United States on December 1, 2022
Color: Olive Drab
I like the knife a lot. Nice blade. The blade sticks somewhat but I'm working on it. More and more use means less and less resistance. It's coming along. It does have a pretty aggressive spring assist but I guess that too will soften over time. As for the strap cutting slot; I don't much care for those and don't even know how well they work. The plan is I never have to find out. I guess they work or they wouldn't keep incorporating them into their designs.
Would I recommend this knife to someone? Yes, I would. With footnotes.
