This review is for the Mantis Knives MT-5 Kunitza. This is a knife that sells at retail for around $110 to $125 dollars, which has been the main reason I never bought one in the past. This particular knife I found for sale NIB on a popular internet auction site for $76, so I decided to take the plunge and snapped it up.

Now I will say that I have experience with Mantis Knives, I own three other of their knives, the MT-1 Sliver, the MT-2HC Class Act, and the MT7.2 Folding Pry. These other knives were reasonably well made and a good value, so I wanted to see what Mantis’ higher end offering had to put forward. MSRP on this knife is a whopping $200.

For the first specs, the size: This thing is 9 inches in length, and weighs 9.2 ounces, which is HEAVY for a folding knife. It is obvious the intended use for this knife is a hard-use tactical folder. Pocket clip is reversible for left and right hand carry, but only tip up.

The G-10 scales are 3D machined and very grippy. They are grippy to the point that they will likely shred my pants pockets right where the pocket clip is. I may sand down the G-10 under this pressure point.

One of the first things I do when I buy a folding knife is usually disassemble it and remove any factory gunk and re-lube and reassemble. Unfortunately, out of the four screws on the scales, three of them stripped out and made it impossible to remove them. This was unfortunate.


Stripped out screw:

The pivot uses a strange six-hole pivot screw, which luckily I had a tool which was able to allow me to unscrew and remove the blade:

Due to the awkwardness of this pivot design, I ended up inadvertently scratching up the black finish on the screws, so, no longer pristine but OK

The recurve black coated blade is 154CM, and 3.5 inches:

The blade has no side-to-side or vertical play, its lockup is solid. The blade is sadly, not centered:

and while it is not directly rubbing on one of the liners, there is an obvious wear mark on the black finish where it rubbed on one side while I was adjusting the pivot:

Blade came razor sharp out of the box and was shaving hairs easily.

I noticed is that the handle is HUGE in comparison to the blade size

The handle shape is somewhat reminiscent to me of the Cold Steel Spartan. The handle shape along with the aggressive G-10 makes the grip very secure in hand. The handle isn’t all great, as
even though the G-10 is heavily machined, the edges are sharp and could have been a bit more rounded off:

It has thick, wide jimping along the top of the blade:

The knife’s flipper works well and requires a slight flick of the wrist to fully and reliably deploy the blade

There are bronze washers on the pivot and here you can see the liner lock as well:

Using the opening hole is more awkward and not very intuitive, perhaps because my hands are not that big. I've kind of figured a way to place my thumb in there to start the blade, and then flick it open.


Here is the MT-5 next to the ZT 0350, you can see the size difference, and looking closely, you can see the cutting edge is nearly identical in size:

and comparing the width between the MT-5 and ZT 0350, notice that the ZT has a polymer backspacer, while the Mantis's is steel (could have had some weight savings here!):

I like this knife, but I am glad that I did not pay full retail for it – in fact I am considering returning it to Mantis due to the stripped out screws, that was disappointing. Mantis has a pretty good lifetime warranty policy and they have done me right in the past. I’ll carry it some more and see. Thanks for reading my review, I know Mantis doesn't get praise on these forums, but I really wanted to share my experience. I feel that Mantis' lower budget offerings actually have more bang for the buck than this higher end folder. All that being said, this is a tough knife, and I think it will stand up to hard use just fine. I can definitely be picky when it comes to spending much $$$ on a knife.

One thing that does bother about Mantis is that on several sites this knife is mentioned as being made in the USA, while others say made in Taiwan. I wish the blade was stamped with this information, as consumers like to know this kind of stuff.

Please share Your experience with Mantis customer service. Would like to hear how they deal with stripped screws.

So I contacted Mantis customer service through their website, with the following message:
Hello,

I recently purchased a MT-5 Kunitza and I love the knife, but when I was trying to disassemble the knife to clean it, three of the screws on the scales stripped out completely so I am unable to remove them.

Is it possible to get warranty work on the knife and have those screws replaced?

I have been a Mantis customer for a while now and love the designs, and hope you can help me out.

Thank you

Jeff


And I promptly receive the reply:

Not if you took it apart, sorry you voided the warranty. We would have done it for you for free.


Best Regards,
Gary West


I suppose Mantis's "Unconditional Lifetime Warranty" is no longer unconditional. :mad: If disassembling a knife voids a warranty, then I don't think a single knife I own is still under warranty anymore then At least I know now not to spend any more money on their products. A disappointing result, to say the least. I am considering letting this knife go and investing in a knife company that honors its warranty.

Am I being unreasonable, or do you think this is something that should be covered under the term "unconditional" ?

Given their reputation, if I was the owner of Mantis Id bend over backwards for every customer they have left. Fail. Again.
 
I don't think it's unreasonable at all. I won't touch Microtech knives now because I found out how aweful it was when I had one. If I were you I would pick yourself up either a Spyderco, Kershaw/ZT, or a Benchmade. They are all excellent knife companies with top notch customer service. I've had very good experiences with all three companies.
 
You never actually took it apart, did you. If I understood correctly, the screws stripped out preventing you from getting it apart. They should honor their warranty.
Looks like just another in the long list of reasons not to buy Mantis products. :grumpy:
 
Gary is Jared's father. Jared is the "founder" if you will. Jared would have taken care of it, his father can't be bothered. (obviously) I work a couple blocks away from their facility and have a good relationship with Jared. If you're interested in sending it to me I will get it fixed/centered/sharpened. You shouldn't have to go through this kind of crap...but there you have it. If you're not bothered in the least or too ticked to be bothered, I understand. I'm just trying to help you out.

Best regards? LMAO. No recommendations or assistance in any way shape or form? Just a sorry you snooze you loose xoxoxo : ) Yeah, screw that company :thumbdn:
 
That does it. I'm selling all my Mantis knives!

Oh wait... :D

Good review, though I can't say the same about the knife or the crappy service.
Mantis used to have a folding Phil-A (fillet, see what they did there?) knife I considered. Ran about $20.
I don't even see it in their product line now. Must have been way too practical. :p
 
Man, I would not let it rest at that if I were you. An 'Unconditional Warranty' that doesn't cover a legit problem with the knife, just because you took a screw or two out? It couldn't hurt to give them another call / email, or to contact the BBB about that nonsense. Might not do any good, either, but it definitely couldn't hurt.

It's like they're actively trying to drive business away...

Mantis "unconditional Warranty" reminds me of this..

Tommy: Let's think about this for a sec, Ted. Why would somebody put a guarantee on a box? Hmmm, very interesting.

Customer: Go on, I'm listening.

Tommy: Here's the way I see it, Ted. Guy puts a fancy guarantee on a box 'cause he wants you to feel all warm and toasty inside.

Customer: Yeah, makes a man feel good.

Tommy: 'Course it does. Why shouldn't it? Ya figure you put that little box under your pillow at night, the Guarantee Fairy might come by and leave a quarter, am I right, Ted?
[chuckles until he sees that Ted is not laughing]

Customer: [impatiently] What's your point?

Tommy: The point is, how do you know the fairy isn't a crazy glue sniffer? "Building model airplanes" says the little fairy; well, we're not buying it. He sneaks into your house once, that's all it takes. The next thing you know, there's money missing off the dresser, and your daughter's knocked up. I seen it a hundred times.

Customer: But why do they put a guarantee on the box?

Tommy: Because they know all they sold ya was a guaranteed piece of ****. That's all it is, isn't it? Hey, if you want me to take a dump in a box and mark it guaranteed, I will. I got spare time. But for now, for your customer's sake, for your daughter's sake, ya might wanna think about buying a quality product from me.
 
I'd definitely e-mail them again. Explain to them that you were unable to take it apart because the screws were already stripped when it arrived new. It seems that the elder West just ran his eyes over your e-mail before dismissing your "unconditional lifetime" warranty claim & didn't even try to comprehend what you said. This company seems determined to fail.
 
I've looked at this knife in the past. Glad I didn't pick one up now. What is it with their locks? The lock on the other one you reviewed went all the way across the tang and this one goes halfway across. My $16 EL-01 has a vastly earlier lockup (which hasn't moved despite hundreds of flick-opens). :rolleyes: I have a Mantis Chaos fixed blade and a Vuja De. Zero issues with either, but I don't think I'll be picking up any more from them, especially if this is how the senior West is going to treat customers. Say what you will about Jared, but I've heard numerous accounts of how he'd bend over backwards to take care of customer service issues, and in the few emails I've exchanged with him he was very gracious and helpful in answering questions. Oh, well. C'est la vie, I guess...:(
 
I decided to sell the knife at a loss, and used some of the proceeds to buy a ZT 0700 from a forum dealer here, can't wait til it arrives :D
 
You have a very open mind, I don't and can't really stomach Mantis, but even a broke clock is right twice a day, and I suppose if you are correct, some of their knives aren't as bad as many make them out to be. I think the warranty is pretty shoddy, and bonafide companies like CRK and Spyderco don't seem to mind their knives being disassembled for cleaning, in fact CRK kinda encourages it.
 
Jeff,
Thanks for sharing your enlightening story about a non-enlightened company.
 
I'm going to fall on the side of somewhat unreasonable. Unconditional warranty, I think, can be abused. And I think it's pushing it to essentially break the knife trying to disassemble it, and then complain when the company scoffs.

That doesn't really let Mantis off the hook, however. If you want to offer an unlimited warranty as a selling point, you have to be willing to put up with everything, up to and including bad faith customers.
 
that sucks. i will personally never own a mantis. IMO it looks like a crap-tastic version of a zt200
