Ultratech OTF Disassembly/Reassembly - How it all works! 

Frankie, you empower me by all the things you show. I don't think that I'd like my Ganzo's without your tweak video. At one time I wouldn't dare to touch a knife with a screw driver until I found you guys! Your Awesome!

Thanks so much for this video, my Microtech UT-X70 stopped working, I made the screwdriver from a smaller one and opened it up, turned out the one side of the spring came undone, I was able to attach it and reassemble it, works perfect now.

Those "little tab things" are the blade locks, and the real strength of the MT design. Precisely crafted with a specific shape, fitted into zero tolerance pockets. That's why MT OTF knives can be hammered through a 2x4 without damage.

If the blade is deployed, you hold the blade and and slide the button to close it, it releases the tension on the spring. Do this before disassembly and you won't need pliers.

You 2 are very entertaining and informative. Thank you both

This was one of my first Birdshot video I watched and I’m still looking for a Microtech. Lol stay safe guys..

It just occurred to me that I didnt understand how this works and your video explained everything! Well done! Thank you !

Cutting mattress tags? Y'all so gangsta 🤣😂🤣

One of the best videos on this. OTF’s are like spring loaded utility knives.

Wish I would have found this channel sooner. You guys are awesome!

"use gravity" best line

Always fun to see. I believe Europe has a new law that products must be serviceable (designed for maintenance)! Important if you drop that in mud, or an end of the main spring fails!

I love otf knifes. Great video, thank you for making it.❤️👍

killer video guys!!!! I liked seeing how it ticks! thanx!!! and I am gonna get me one of those microtechs one day

After struggling for two long hours trying to get mine reassembled...I ran across this. Sigh. One comment. You are brave souls to take that apart on a charcoal grey rug! 😃

always wondered how these work. thanks for showing us

Is there a place that sells the main spring? I’d like to have a couple on hand.

I only had my Ultratech a few months. But my Lightning would fail to open from time to time since day one. I sprayed a bit of gun oil inside through the opening and it has yet to fail to open.

Awesome explanation 👍👍. I was wondering and now I know . Schooled . Thank you .

thanks for letting me know how this thing works without having to take it apart myself! also, ultratechs are the finest objects ever created by man. or was it?

I’ve made a ghetto bit from grinding into a coathanger.

I like using zeplon dry spray lube, its like a Teflon spray for lack of a better explanation. But it sprays on wet and gets where its needed and drys so it doesn't attract dirt. It will leave a white residue on some surfaces, but I've been able to wipe it away. Not saying it won't stain but I haven't had it stain yet.

Wonderful instructions complete and simple

Just curious what y’all think about the Ultratech , Iam getting ready to get me one d/e dagger 🗡 blade style

Great video- Thank you!!

Okay, old post but I have a question; is there a fix for the minor rattle that can be experienced because of the blade pin? It's tight but still...I've tried fastening it with a tiny piece of yarn along the side, but I've read a non rotating pin can cause damage (repetitive impact on one side of the pin). Is this correct and is there a fix? I can live with it, but I'm a little ocd about rattle, even in otf's.

Great video guys.

glad that was you taking it apart and not me otherwise it would still be in pieces

woooooowowowo thanks you guy. the bird is awesome!!! 👍

It’s only under spring tension when you move the trigger one war or the other...when it’s open or closed it’s not under tension

I want to disassemble my UTX 85 to sand blast and stone wash the blade and body. Other than a voided warranty, anything you recommend I do?

I'm about to send mine it. When I push down on the actuator it sometimes I have to push down twice to get the blade to retract. Ugh

So how do you make it so it does not pop off rail when open it into an object

I know i'm a bit late. But is the mechanism on a benchmade phaeton comparable to this?

Good video. Thanks.

Hi, do you know the specs for a Combat Troodon spring? That is length, wire diameter etc.

👍's up and enjoyed. Sure would love to see some more cut test. May the blessings of the Lord be upon you all.

It’s actually a really simple design. I’ve cleaned out a few for buddies that quit working either got dust and grit in there or oiled it too much faster than sending it to micro tech lol

You have skills!

That's much more simple than I thought

Is there springs on the gates?

If you and frankie have time soon, I'd love to see a combo knife video summarizing your favourite recurve blades. I know you guys have a ganzo and a ZT that're quite curvy and I was wondering if you guys had more or any suggestions on what would be a good one to get that is most worth the price. As always, love the channel and the vids! :) Thanks

Lol to hear people talk it's like a Swiss watch in there. Nice demo. Would be no big deal to pull this apart for a clean and lube every now and then.

Where can I get replacement springs?

Pretty dope

Thank you

Hi guys. I really enjoy your videos and learn a lot from them. They are fun to watch. Several of my knives have stripped pivot screw heads They stripped after only a quarter turn. Yes I know, cheap-o's. Can you recommend any place to order replacements? Thanks.

good video guys

Which is the one you void the warrenty by sharpening it? Is that microtech?

I have a question. What type of knife if any do you carry in your car?

lovely couple

Where did you buy the proprietary bits?

I thought this would end up like when they opened the Ark in Raiders, nope!

🐦Nice disassemble Johnnie 5 lol I like my white lightning OTF ,I rented that ten cloverfield lane awesome especially the end 👽 I just got a outrage and a amicus sweet 🔪

Definitely interesting to see and know -- even if it does void the warranty. (still better than violating the LAW; already mentioned my sadness over not being allowed to own something like that where I live)

You can buy these knife wrenches on Dhgate for around $10

You can take the blade out of it if you remove that round pin at the bottom of the blade if you just turn the knife upside down it will fall out just make sure not to lose it

So anxious that these small parts are on grey carpet and not a contrasting color rubber mat or something

Dirty Talon... I like it!

"Hey Franki, you ready to void a warranty"? HILARIOUS!!

Hey Birdshot IV!! I was writing in the hopes that you’d be able to help me find a 09/16 microtech it’s my wife and I’s anniversary and I’d like to get a piece that reflects the day my life changed forever for the better. Thank You for your time and content!

what is the warranty? If you have a problem with springs flying....Disassemble/assemble in a clear bag.....and use magnetic trays, you will never lose parts....... Cmax

This helped me fix my knockoff ultra tech that my mom got me off wish 😂

very cool. :-)

Just to let you know, I know this was four years ago, but now, you don’t need a special tool. I have the exact tool in my toolbox. And they came with the set. I just open mine so I could stretch the Spring, it was too tight.

I have a secret. they would never know that u voided the warranty unless you told them. HUUHHHHH

Price in India otf knife

So, why isn't the knife community up in arms yelling "CLONE", regarding the mechanism? Well, it's because we are not taking about a Chinese brand, that's why. Thanks for this video, it is cool to see how these actually work. since they are illegal in Canada I can't get my hands on one to see for myself.

Nice breakdown Frankie! How would Microtech know you opened the knife - is there a seal?

This video is why I'm 250 bucks poorer

Hey Frankie and bird if you ever consider selling one of your microtechs I'd be interested in buying it. Much love from Ireland 🇮🇪 😁 Or a 940

any butterfly knives??

How do i get the tool for it

Dude putting your hand in front of that blade opening while playing around just asking to get stabbed

Does opening a Microtech void the warranty? "We understand that some customers may prefer to maintain their own knives. Sharpening your knife does not automatically void the warranty. The warranty will remain in effect so long as the blade is not improperly sharpened and the handle is not damaged or stripped due to disassembly, determined at our discretion. Sep 7, 2020" MICROTECH So yes you can take it apart as long as you're not an idiot!

What are the clips that hold the spring in place called? I need to find out where I can but replacements.

👍🏼👍🏼👍🏼

Yall need to make another camping video, its going to be sad without Mikka if yall do it

I didn’t think they can legally void the warranty anymore.

Do you think microtech would really deny you warranty work if you disassembled the knife to clean it but didn't do any damage to it?

My rear spring hook broke. I opened it myself. I'm fuuuuuuccckkkeddd

Trophy wife 😂🤟

VOIDED!!

Lol how would they know if you opened it up? Is sharpening a Microtech really a warranty killer??

Ok? Ok!)))

The design used by MT is quite universal. They didn't "improve" so much as they beefed up the parts. This is most obvious comparing the blade locks to other brands and "non-brands". Other's have slightly thinner locks which means they can be deformed or act to deform the handle material if the blade is advanced through heavy resistance....this is why all the MT fans love to hammer the blade through a 2x4 to show the front blade lock will hold up. Another feature is properly hardened and heat treated components to keep the steel from bending or peening, or the rear hook from bending. Anodized aluminum places a diamond-hard layer of aluminum oxide over the soft aluminum, and this helps prevent the substrate from being "easily" deformed...doesn't mean it can't be, just that it takes more to fracture the anodized surface in order to start spudging the aluminum underneath. While MT advertises the latest exotic steel used in the blade, the real secret sauce is how well the blade and all other steel parts are heat treated. On inexpensive knives it's not the 440C stainless steel blade that's inferior, it's the thinner blade locks, thinner blade cross-section, thinner steel rear hook with little or no post-heat treatment, and of course either bare aluminum which means a soft surface save for the slight layer of oxide that forms naturally, or Zinc alloy which is quite dense and heavy, but also relatively "soft" and more easily deformed. MT OTF knifes are really more of an example of how good you can build a universal knife design when using quality components than anything exotic....and that's not a bad thing because the simplicity of the design helps to make the knives more reliable. Remember, the parts you leave out, can't break! Having said that, in a SBS comparison I suspect the Benchmade Infidel is ultimately the stronger design. It starts with a steel chassis frame which adds strength while the handle slabs add stiffness. The blade is locked by twin locking arms on either side, and those arms are hinged to the steel chassis. The "weak-point" of the BM design might be considered to be the miniature leaf springs placed in layers to tension the front and rear locks, but in the right application leaf springs can last nearly forever, and if broken are easily fabricated - much easier than fabricating a miniature coil spring! The blade locks, beside being hinged on the steel chassis plate, are held in place by the steel slide, and all stress forces are carried in-line down the plane of the steel. With the aluminum, or Zinc in the case of clone knives, handle halves screwed down tight from both sides, the steel chassis plate is prevented from buckling. I don't remember seeing anyone doing a hammer test on the Infidel but it might be an interesting comparison. Another interesting comparison would be to see the hammer test performed SBS with an authentic MT and a clone version - done by an independent tester to find out just WHERE The cheaper clone knife gives up the ghost comparted to the 10x more expensive MT or BM. The REAL comparison would be both knives carrying out the normal uses...cutting cardboard, tape, stripping wire, slicing off small branches maybe, and being plunged into a human torso and head constructed of ballistic gel with simulated ribs and skull. I doubt anyone outside of a RU-vid video is carrying around an expensive OTF looking for opportunities to damage it beyond repair doing stunts any $20 fixed blade knife could do better, faster, and without any concern over potential damage.

It says on the manual that simply disassembling doesn't void the warranty, actually. There's a pdf of the manual on their website if you've lost yours.

How relevant is this video to new ultratechs? Their marketing material says the springs are always at rest in both the closed and open position which is the opposite of what this video says.

FIRST!!!!

They don’t void the warranty only if you modify any parts does that happen

So technically its not an automatic, its a spring assisted

Microtech springs are NEVER in tension whether opened or closed. That is information straight from microtech. Why do people keep saying that the spring is under tension? Visit microtech.com for any technical information.

when you're done sell me the knife I want it really bad or donate it to me for loving your channel so much . pleaseeeeeeee great video guys

im not a fan of the atuo knives

How the fuck this knife cost 300? It's so simple and there are many better blades

Lightning is not a stolen design, that's just how all otf knives work.

Your girl sounds like shes about 8 years old.

oh wow. those look super cheap inside compared to hawk deadlock. not near as simple either. and definitely ugly. lol. looks like i must save my pennies for a deadlock now :( :)

OTF are extremely simple designs and it's absolutely bullshit that they cost so much.

How would they know you disassembled it?
