3:30 Video review starts. 4:25 Opens lock.

Great story about birthdays. OPEN THE DAMN KNIFE

whitin 5 mins i was like: JUST SHOW HOW THE THING UNFOLDS ALREADY

I swear if Valve puts this in CSGO.... Ehh shit I still want one.

On my sixteenth birthday I got my finger caught in a belt sander and spent the day in the hospital blasted out of my mind on narcotics.

Pronounciation: "Voo-ja Day Bloo" As in deva vu backwards, with a "blue" at the end.

This is literally my two favorite knifes combined! :0

yes sir your right, the sickle being an extreme version....

Have to say, I use this knife daily and I love it, it functions well as a utility knife and I also carry it for defensive purposes. After carrying a regular balisong for a little over a year it was hard to get used to opening this knife but I eventually got it, you just have to keep in mind this knife was not designed for tricks. I love this knife and would recommend it to anyone.

Two of my best friends recently got their own kerambits. I had wanted one of my own, though I hadn't found one I liked until now. Not only do I like it, this is one of the coolest, most unique knives I've ever seen! Thanks so much for the video, Jeff.

When you hold that kind of knife the way it is supposed to be held in combat, The way the blade crests reminds me of a bee attempting to sting something with its abdomen.

My two favorite knives fused into one! WHAT Edit: Does he flip it?

I liked the vid, love you and your ideals. Holy cow over 5 min and we haven't seen it deployed!!

Oh god that is beautiful

Another beautiful knive jeff thanks for shareing my friend,great review as aways keep the video comeing.......

thanks for the awesome vid bro. as a flipper and a karambit fan, i was looking at this thing since it was announced. after this vid, i kinda think imma reconsider getting this. i was honestly debating between this and a kimura v, and having to choose, i'm more of a flipper at heart. keep up the good work man.

This looks phenomenal, love karambits and this is so cool, definitely saving up my nickels and dimes for this

your reviews are great no matter what subject

My two favorite knives in one.

I may acctually get one of these the concept is amazing

Unfortunately this is illegal in more than one way where I live. May not let that stop me.

Great Video! Thanks For Sharing! Now I Want One!

Just ordered mine how dam cool is that Thanks JEFF!

That design is pretty sick. Really cool.

i became in love with it as soon as it was opened

Jeff I watched 30 of your knife review videos today because I am obsessed with knives since I got my Boker Kalashnikov!

Great video, thank you!!

For backwards pocket clips, I just put the knife into the main pocket and clip it to the little coin picket or whatever it is, so its clipped and secure, not hanging out but facing the right way. Give this a try if you can't or just don't want to flip the clip. Hope that helped.

very cool knife jeff, being a great guy pays off when people show their love for your channel by saying to themself, hmmm. thats cool I bet jeff would appreciate this and then make a kick butt video about it, well done my friend

Yet another really good Knife review! You covered every question I had. pretty cool looking knife too. Might have to check it out. It doesn't seem like a flipper to me at all but a very usable knife nonetheless..

Awesome knife dude. Very unique.

i got the black one i love it and very well made my 2 fav style knives in one

awsome man thanks i was thinking about getting it cuz i am also a karambit fan but could neverfind one of my style or one thats scary enogh and now i want to get this awsome thing for EDC purposes and utility

I need one of these so bad I'll trade any limb you like

Having seen every one of your videos, this is probably my second favorite knife that you have reviewed. It is second to your crocodile knife (The spyderco worker). This is also the first knife that I really like that I can afford, so I will probably be picking one of these up in the near future.

The things they come up with... Thumbs up!

@cutlerylover im looking into a decent kershaw and ive decided i want either the cryo or the scallion which one do u think would be a better edc knife

I'm glad Mantis finally got around to putting these out. I heard that a lot of what they had was stolen from Blade show last year. I'm gonna have to grab a few of these. Very cool design.

Nice vid Jeff as always:)

What case was that in I've checked steam store and still couldn't find it

That's HELLA SWEET :)

DUDE that thing is cool as hell... ive gota get one now

now thats an interesting Blade. props to the designer.

the cuts are on the top of the blade to give more pressure on the tip of the blade while pushing there. while pushing, your thumb wont slip just like on the handle

thanks for the vid! I saw this on bladehq and was wondering about it.

I have to ask, because I have looked everywhere I can. Is there a place I can get a fixed, double edged karambit for under $50? All the karambits I have seen ore single edged, even though from what I know, the traditional ones are double edged. The ones I have seen that are double edged are either falsely advertised as such, over $50, or custom made and over $200. Why is it so difficult to get a double edged karambit for cheap?

As many of the peeps are suggesting, a video of you flipping it, or even coming up with some tricks specifically for the Vuja De would be pretty cool.

would u suggest this knife for self defense or the cold steel tiger karambit

What kind of work is this rediculus thing supposed to preform? A knife it a tool that's maybe a box opener however the end of the blade doesn't appear to come to an edge

do you recommend gerber knives or do you think they are good knives? a reply would be awesome. thanks!

The fact that Mantis knives has packed a hawk bill in such a small package is impressive. Most curved blades on balisongs also have curved handles or are quite wide, I could actually get some work usage out of this one.

Pretty cool looking knife there Jeff

You should review the mantis vicious circle neck knife

Does anybody got this knife recently but instead of the one in the video the ring in yours was a little bit oversized? It is posible that Mantis changed the model or something? To make it worse? :(

amazing knife

Not sure why I find this unnecessarily interesting, but great video. What a cool knife.

Oh god I want one of those so badly

quite a fitting name for the knife, because it's something never seen before

So, basically a butterfly knife karambit?

I love your vids man but I haven't seen this knife before I nearly died having to wait 5 minutes to see you open it up xD

Thanks for showing this to us all, but now I have to have it. Damn you.

Hey Cutly, i enjoy watching your videos so much, just a dude checking stuff out he really is keen on, a bit of wtf is that and a tad of proficiency in what he is talking about. Keep it up my dude.

Should I get it

That's a awesome knife

How much will they cost? Are they legal in Australia

wow that's sick I want one

I love karambits... I love balisongs... I LOVE THE KARAMBISONG!!!

I am saving up my money for this, but do you think it is worth its price or should i buy another knife around the same price that may be better.

Thats a very cool blade. I'm gonna have to find one :)~

you could also totally sharpen up that swedge, and have a double edge like many fixed blade Kbits. Which is nice specially for revearse grip tactics.

Damn, that's a really cool knife :D i could see alot of possibilities of flipping it due to the ring at the end. I can see poeple making tricks with it, or maybe not :P

Are you going to do a review on this knife in the future? Thinking of buying.

how is the build quality of this knife? Does the fit and finish feel solid? I am interested in picking one up :)

Would you consider this a quality knife (specifically the blade)? Or just a cheapo knife with a complex cool mechanism?

Yeah yeah, but is there one in marble fade?

Is this Stat-Trak?!

Is there a practice version of this knife?

That’s sick

Cool knife!

OK i am from NYS and i know there was a repeal on balisong's illegality because they aren't considered a gravity knife anymore... now i was wondering... would this thing be considered a gravity knife? Because of the locking mechanism and it not being a true balisong? I am interested in picking it up but i'm wondering about it's availability and even being ok to carry in NYS..

dam i want one but i guess its worth lots to buy and if it was like the balisong flipping that would be awesome

"It's not going to float everyone's boat" haha WHO'S BOAT WOULDN'T THIS FLOAT?! xD Love your videos man!

Thats so cool......... I wish we could carry balisongs in Texas, this would be a cool novelty knife to carry.

i was just reading a article in tactical knife magazine about karambits

my brother was the one who contacted mantis about making a balisong and him and karambit lover both pushed on the mantis forums to design the knife. cool fact :)

This is interesting, I thought you would do tricks with a Karambisong, but it seems more like a karambit that you could put in your pocket, without stabbing yourself.

have you done any stress tests with it? I know from personal experience that Mantis' MV-X steel is usually pretty bad, or just a coverup for using cheap steel.

You tested my patience there for like 5 and a half minutes. OPEN THE KNIFE

props for them for trying new unique things though

can you do a video comparing the VUJA DE and the QTR-9 K.I.T.T

One of those knives that at first glance doesnt look like much but over time grows on you. just but one. probably gonna grind down the ring and remove the spring to make it flipable.

So because of the locking mechanism is it a balisong or a folding knife. My state does not allow the carry of balisongs so that would throw my desire out the window.

This a solid piece for my first knife fight?

I NEED THIS

Its all good.. normally I would just want to "get to it" but... As you've mentioned in a previous video.. Some people just have a personality you like.... I enjoy your videos.... beginning middle and end.

that thing is sick

Good morning from North Nj, your homeland wishes you well :p

Do you know much about the M-VX steel that Mantis uses? Is it pretty good stuff?

Where can I get one of these

I remember before people started making money on KZfaq. people would post not worried about others option. now it's all about the "viewers" instead of personal opinion this is his channel if he wants to talk it's his choose.
