The 3" satin finished, drop point D2 blade opens and closes with a slide of the spine trigger. The tolerances on this OTF are incredible.

The blade anodized aluminum chassis has curves and jimping in all the right places to give you a comfortable grip. The distinctive SOS logo is engraved on the spine.

All hardware is black and the clip is tip down.

    Feels really quality, action is pretty punchy and out of the box, the knife was really solid. The clip could be better and more deep, but everything else was pretty solid.

  • Revised review on SOS OTF w/drop point blade

    Posted by Richard Kennedy on Mar 17th 2024


    This is a revision to my earlier review. In fairness to this knife, I was a bit critical in areas that turn out to be unimportant. Specifically, I felt the knife's case was too slippery. However...the great jimping on the bottom of the case gives excellent grip, making the slipperiness no big deal. Also I didn't give enough credit to the fit of this thing. Once the blade is deployed there is no slop, no movement at all. Those inner tolerances are really close. And even the way the two case edges fit together is noteworthy. SOS, you have a winner here!

    So far I'm quite pleased with this little guy. D2 blade steel, mine arrived quite sharp, and the fit and finish are, in a word, outstanding, especially when you consider the price point. The knife is plain, the housing appears to be anodized aluminum. The sides are smooth and almost slippery. As you can see in the photo, there is some jimping on the bottom of the case to help with gripping the knife. The deployment action is somewhat stiff and the blade shoots out with authority and a nice, healthy snap. There is virtually no blade play or slop, so time was spent making this blade fit in the housing. The only reason I am giving this a 4 star instead of 5 is the lack of grip area on the sides of the case, it can be on the slippery side. In all other aspects the knife earns a 5. Very pleasing, great value.

  • Editing A Previously Submitted Review

    Posted by Jeff on Jan 19th 2024


    After taking this knife apart, cleaning it, and lubricating it, I’m submitting this review as an edit to my previous review, in which I gave this knife 4 stars. I gave this knife four stars because it came stiff and greasy and would like to retract this statement. Yes there was grease on the button track and in places on the knife, but that is completely understandable as the manufacturer would want to keep the knife lubricated while in storage, and grease is great for that. Also, in regards to the “stiffness” or difficulty opening, this is my first otf, so I didn’t realize that stiffness is a good thing with OTFs as it is a measure of safety against accidental deployment. Yes the action is a bit hard to open, but when it does, it is a very short switch throw and rapid response. It’s incredible. The return is just as snappy. The movement of the blade itself and the button are not at all ‘stiff’, everything moves smoothly on track. The switch just requires some oomph to fire, but it isn’t much. The knife is far easier to disassemble and reassemble than I imagined it would be, with my only hiccup being that I needed to learn that the spring is directional in terms of how you put it in. It has bent tabs on either end, one short and one long, that latch onto the slide plate. I didn’t realize that the short end goes on the front of the plate, and the long on the rear. Also, though it may seem counterintuitive, you can’t have the blade locked back when assembling, it needs to float about halfway along the length of the railing and you’ll be able to get everything back together.
