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

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.

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

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

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.

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

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.

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.

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

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

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

That design is pretty sick. Really cool.

Oh god that is beautiful

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.

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

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

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

So, basically a butterfly knife karambit?

My two favorite knives in one.

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.

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

your reviews are great no matter what subject

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

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

I may acctually get one of these the concept is amazing

now thats an interesting Blade. props to the designer.

Just ordered mine how dam cool is that Thanks JEFF!

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

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

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

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

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

Nice vid Jeff as always:)

@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.

Great video, thank you!!

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?

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.

Awesome knife dude. Very unique.

Karambits were originally just small sickles, but like almost all martial arts weapons, people found that they could carry them around as self defence tools without being questioned.

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

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

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

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.

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

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? :(

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.

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

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

Is this Stat-Trak?!

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..

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

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

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.

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.

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

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

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

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

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

no, they only had one folding karambit, and it wasnt a balisong, that was my point, to say just buy an emerson is like saying if you want an endura just buy a cold steel voyager, same thing right, lol

You should review the mantis vicious circle neck knife

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

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

wow that's sick I want one

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.

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..

For this knife in UK, would it go under the same law as the Balisong, and be banned. Or under the Karambit law, And not be banned?

Jeff, how practicable is it to use a ballisong for EDC? I like camping, Survival, And bushcraft. I'm wanting to try something new, And my birthday is coming up on the 14th! And I'd much rather take an opinion from an expert. My typical kinda knife is just a pocket knife or survival knife. Right now, My EDC knife is a Gerber Bear Grylls folding sheath knife and a Gerber obsidian. (I like Gerber(: ) But please reply! thanks in advance!

yeah because i too was very curious to see how the knife look like. but the difference is im not impatiant

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.

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

That's a awesome knife

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.

The CS:GO Players Dream

That's HELLA SWEET :)

How much will they cost? Are they legal in Australia

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 :)

Yeah yeah, but is there one in marble fade?

There are a few custom knife makers that make karambit balis. Yes, they will be more expensive, but they're out there.

Is there a practice version of this knife?

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

is it suposed to be carried on your weak side so like if you are right handed is it supposed to be on the left or something

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.

Got this knife months ago and played with it a little bit. Very interesting design. It could be the first production bali karambit, but not the first ever been made. Warren Thomas made some custom bali karambit, and I think those are superior designs than this one. My mean issue with Vuja De is the ring is one the bite handle, makes the opening fairly awkward. Thomas puts the ring on the safe handle, which would make the opening easier and faster.

Pretty cool looking knife there Jeff

amazing knife

Oh god I want one of those so badly

I can already tell that this thing will be great at ripping boxes open and slicing thick cardboard with a nice strong grip. My speakers are broken so I can't hear the video, what's the steel on this blade?

Alabama leprechaun is the funniest thing I've seen this week lol

Not only is it a folding karambit, its a karambisong. Its the trifecta

Just got my Mantis MK-1 today . FOr a 30 dollar knife its badass. what a coincedence. Also its strage cuase mine somehow came with that M-VX steel which suppose to cost more. It also had a few other changes from the current model I see everywhere else...not sure if I got something that slipped out of the factory early or something but its defenitley not going back.

that thing is sick

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

It's actually just called a Mantis Vuja De, I assume that it just says blue on the box due to the coloration on the G10 scales.

Hey jeff the heavy jimping on the blade is for selfdefence purpose, martial arts application

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