First off, I've had this knife for 8+ months, I carry it daily along with my endura 4 and para 3 Spyderco knives. For the price I love this thing, the quick deploy is delightful, still works. knife edge retention is about what you can expect from a knife that's 20$, it would be short sided and idiotic for me to complain that it doesn't hold up as well as my endura (vg10 steel)...If you don't know how to sharpen or pull it across a "V" sharpener then probably not the knife for you...but that says more about you than it says about the knife. I recommend the smiths pocket diamond sharpener, 2 passes on the conical honing end and it's back to a razor. The guy that posted not 1 but 2 videos of the knife failing to fold...should stay away from sharp objects, for one the way he attempts to fold the blade back in is a great way to cut yourself....were it possible to just press the blade into a table to close it, which it isn't(that would be a terrible design). The knife has a liner locker....so trying to "close" it with blunt force is an excercise in futility along with being equal parts laughable and depressing. I hope someday he figures it out, and changes his review, operator error is a poor reason to leave a 1 star review....you got outsmarted by a 20$ knife, I'm sorry you didn't watch the handful of other videos showing the action for both deploying and folding/sheathing the knife. For the people saying the blade became so loose it wouldn't be safe to continue using because the liner locker wasn't catching....buy a screwdriver set for electronics, 120 pieces with all the torq/Philip/Allen tips you will ever need to tighten your knife...or just throw the knife away because basic knife maintenance is beneath you and you would rather write a scathing 1 star review than turn a screwdriver a half rotation. Might I recommend a fixed blade, mayhaps one made of rubber, wouldn't want you to hurt yourself. And last, the people that said the belt clip was garbage....I'm sorry but do you not have a screw driver either? Once you understand the basics of the buffer rings and one screw threading into the "bigger" hollow center "screw", this sheath has a plethera of different builds for any kind of deployment, direction, or hand dominance preference....and for the likely same handful of folks that couldn't keep it clipped on their belt or couldn't open it to clip to their belt....it has a locking mechanism, slide it over and push the release, if it doesn't depress you slid the lock the wrong way, then once you have it clipped, I recommend clipping the sheath on a belt that isn't already securely fastened around your waisted, unfasten your belt, leave it in the loops but get some slack wherever you intend to attach, press until it clicks, if it won't click....you guessed it, it's locked and you just have to slide it 1/4" to the other side, *click*....oh whats this here? You can lock it once it's attached to keep it from bumping and some how miracling it's way off your belt? Astounding! Also in case this wasn't obvious, okay, you're right, clearly it wasn't...there are little black bars of plastic that come with the clip....you may be wondering why? the clip can fit on a belt around 1.5" wide, if yours doesn't, it's because you have those little black retention bars already installed on the clip simply pull em out, you can also use them to hike the sheath up on a narrower belt or allow it to sit lower on your waist...play around with it see what works best. Pro tip: if you can't get the retention bar out by pulling on it, don't bend it back and forth simply turn the clip so the back of the retention baris facing you, using a small straight blade press out the center fastener of the retention bar...viola.It's a great knife with a unique deployment action that I haven't found on any other knife from any other knife maker, I would love to know if someone is doing it better, I'm aware of the Emerson wave on Fox karambits, but this is a different action for folks who like the kydex sheath and the ability to adjust directional deployment.

I really didn't know what to expect when I bought this knife. All I know is.....auto deployment holster? Cool. And that's really the only point to buying this thing. For the cool factor. Really, what is the real benefit to having a Karambit style knife to the average non-ninja type person? It's not practical in everyday use like a pocket knife. And, really, unless you are trained to use this thing in combat, it's useless in a self defense situation. Plus, I am not sure i'd want this thing up on the evidence bench in a courtroom in a trial investigating a self defense situation. Anything scary looking, will definitely NOT be in your favor in those situations. With all that being said, let me say that it's a cool looking knife. And pulling it out of the holster is really cool too. Provided you pull it swiftly enough, it does snap out and lock. And if you handle it right, it should snap out into your hand perfectly (make sure you put your index finger through the loop and keep your hand open when you remove it from the holster). The black blade is nice looking. It's fairly sharp. But if you are going to do practical things with it, get it sharpened professionally first. But like I mentioned earlier, it is highly impractical to use this thing in every day applications. It's just awkward to try and cut with at best. So, if you are a knife collector, this is definitely worth the coin to add to your collection as being a cool toy. Also, one more thing to mention. There are absolutely NO instructions on how to assemble the holster belt attachment. It's not incredibly hard to figure out, but just a forewarning. You WILL spend a few minutes trying to figure out how it goes together. And it's also worth mentioning, you will need a torx bit set to put on the belt clip it also comes with. Well, that's it! Review done! Now stop reading and buy this thing. It's neat. =)

So, like others, I was expecting a spring assisted karambit with a nice holster system... I was initially very disappointed that the knife has no spring assist. However, once I configured the very nice holster, I am very pleased with the action of the knife. On a one-handled pull from the left side of my belt, the knife opens automatically about 90% of the way on a standard pull (not quite far enough to lock, but close). Pull it out fast and it will lock open (but be careful). This is made possible by the very nice design of the plastic sheath (holster) that grabs the thumb stud and forces the knife open as it's pulled out. If you added a spring assist to the design, it would snap open all the way and lock on sheath exit, which would be amazing.-I recommend reversing the side of the knife the clip is on -- takes a very small torx bit, this way the clip does not interfere with the holster.-I also recommend removing the spacers between the sheath and the clip and putting the spacers on the outside face of the holster so the knife is closer to your body. You can only do this after you have reversed the clip.Back to the knife. The design is very nice and very lethal. The angle of the blade relative to the handle is more functional (for doing damage) than a lot of the other decent folding karambits available right now (which are more obtuse). The quality of the handle is very nice. Fit and finish are very good. The knife is almost razor sharp from the factory. A mild polishing and it would shave hair. Nothing to complain about besides the lack of an axis spring assist. It is an overall very good value at the price paid (May 23rd, 2017).I have no affiliation with any knife company. Just a user / collector.
