I have to say, THIS IS A GREAT KNIFE. It does everything I want it to and more. If you can think of a way to open this knife it does it. You can flip it, you can drop it, you can thumb it, you can flick it. The detent on it is well balanced for all these applications. From a materials perspective...it impresses. The carbon isn't flashy but its well done. The grip feels nice in the hand. Not to slippy and not to grippy. The tolerances are all great(as expected from the taichung factory). Blade is centered well and I'm happy with S30V as the blade steel. Aesthetics are fine. Some wont like the lack of a sharpening hole but that's not as big a deal as some would have us all think. Blade shape is great and over all size is perfect. Lock up is strong and has a nice "click" noise to it. Especially when opened with the thumb. The barring system is outstanding. If your considering this one I would recommend it. Its an all around winner for me. While its not perfect...It's pretty close. Happy collecting all.
It looked safe on paper, maybe?

Spyderco knives are usually designed entirely for function; indeed, you could say their design philosophy is that looks don't matter, only functionality. The now iconic Spyderhole is the most obvious example.

That said, the Mantra 3 is...perplexing. There are some serious design problems, especially one that is flat out dangerous, which seem like they could have been easily avoided.

Firstly, the flipper and the compression lock on the back of the handle interfere with each other. When flipping the blade open, the index finger impacts the lock bar as just as the blade is swinging up and trying to lock. This USUALLY does not prevent the blade from locking up, though that can happen if one's finger hits the lock just right (or wrong).

What's worse, the flipper tab makes it difficult to close the knife one-handed because it strikes the index finger as it's closing, this time going the opposite way than when deploying the blade. In other words, when the compression lock is held open and the knife given a little shake to close the blade (anyone familiar with Spydercos that have this lock, like the PM2 or PM3, will know this maneuver very well), the flipper tab on the blade very frequently hits the finger holding the lock open, which causes it to not fully close. This problem of the tab hitting a finger also makes it much harder than it should be to open the blade using the alternate method of holding open the lock and flipping out the blade with wrist action.

However, these are minor annoyances compared to the biggest design flaw--this one could earn a trip to the emergency room. The Mantra 3's handle flares out and curves downward beginning about 1/2" behind the pivot screw, and when holding the knife, Spyderco apparently assumed users would always keep their index fingers behind that curve and away from the blade. But the handle is rather small and it feels quite natural for the index finger to slide a bit forward, to about even with the pivot, so as to rest on the flared curve of the handle. Other models, such as the Manix 2, actually have a finger choil in this spot to allow one to choke up. But the Mantra has nothing: the flipper hides behind the curve in the handle, and the blade's cutting edge goes all the way up to it. In other words, if you move your index finger forward on the handle to choke up a little, which is a common and often useful way to hold a knife, there is nothing to stop your finger from sliding right on to the sharp edge of the blade.

This is dangerous, and I cant understand why Spyderco didnt put something, even just a small notch in the blade, so that the line of the handle didnt flow uninterrupted onto the sharpened blade edge. The problems with the flipper/lock would have required a redesign to a true liner lock to correct, so I can understand not wanting to do that (though the other Mantra models are configured that way, I think). But this very big issue could have been solved with a small change in the handle shape or the addition of a half cm notch in the blade.

I could probably grind a choil into the blade and fix it myself, but I have too many good knives to waste the time. But I like my fingers attached to my hand, so I'll just have to decide whether to gift this knife to my cousin who is missing part of his right index finger, or to someone I really dislike.
Let's address the elephant in the room...

I don't think it is any secret that the recurve going from the base of the blade to the flipper tab is one of the biggest downfalls of this knife. EVERYONE that I have talked to that didn't like the knife has cited this as the reason why they don't like it.

With that being said, the recurve isn't very big, and if you are halfway decent with a sharpening set, you can sharpen the recurve out like I did. Once that issue was addressed, I have to say, this knife is KILLER!!!

I love how lightweight it is, how simple it is, how snappy it is, how smooth the bearings are, and how THIN the edge is. This thing was built to slice!!! And while a lot of people hate the wire pocket clip, personally, I love them! I don't need an overbuilt, CNC machined, mokuti pocket clip. I need something that is going to keep the knife from falling out of my pocket, and the wire clip does that just fine.

The compression lock was a little different for someone who has had zero experience with one, but it doesn't take long to get used to it.

All in all, I REALLY like this knife. If it weren't for the awkward recurve that I had to sharpen out, this knife would definitely earn itself 5 stars.
