5.0 out of 5 stars Great knife
Reviewed in the United States on December 21, 2023

As an owner of ten zero tolerance flipper knives, for me to try another manufacturer was a stretch. SOG got this one right. Great balance, sharp and built well, with no play in the blade when deployed. The blade release button for closure is really nice too. Yes it is large and a bit heavy, but the feel is welcome and solid, with a confident grip. I have large hands so the size is not a problem, the jimping on the handle and deployment is a bit coarse, but not a problem. I guess if you have small soft hands don’t buy this knife, otherwise it’s a winner

I am kind of a knife snob. I have several EDC knives and this is my favorite. It's opening and closing is so smooth. Even though it is a larger knife , I do not notice when in my hand. It has the most solid deployment of any knife that I own. This is a workhorse while still being a great EDC knife. I can trust this knife to do everything that I would ever ask of it. I plan on buying at least two more for me, my friends and family. Buy it! You will love it!

This is a heavy duty knife, built to take whatever you throw at it, or throw it at lol. Came adequately, sharp, out-of-the-box, function, smooth and flawlessly, this is a well above average quality knife, which I got at a decent price. I carry this for self-defense, and also as a professional for an emergency tool as good or better as any of my other USA made knives.

5.0 out of 5 stars Excellent EDC knife (that looks like a Special Forces knife)
Reviewed in the United States on September 18, 2023

I keep this on me when walking deep in our inhabited wooded area. For safety. The grooved edges on the outer spine make it a little uncomfortable at times (especially on the quick-release knob). And it doesn't open as smoothly as less expensive knives I have, but the quality of this knife is unmatched. If you only need one knife, this is it IMO.

Can almost shave. only wish the clip was even with the butt of the knife so it sat a little lower in my pocket. As it is now a bit of the knife end sits above my pocket and is noticeable. Other than that this is a one solid pice of steel that opens easily and works as advertised.

Can't believe such a BIG, HEAVY fold is as easy and as comfortable to carry as this one is. I was really concerned when it arrived with it's weight alone but so far it's a non-issue. If you have big paws she's a dream in the hand, but again she's a BIG, HEAVY girl. :)

 I have wanted this knife for a long time. When I saw the discounted price, it was a no-brainer. It feels sturdy and substantial. It clicks open crisply with the flipper tab and it locks up solidly. The XR lock works flawlessly for me and it is fun to fidget with.

If you read the description, you know going in this is a bulky, stout knife, with aggressive jimping and texturing. If that is what you’re looking for I don’t think you’ll have any complaints.
