The Inside Of A Microtech Ultratech & How It Works

[@locksmithdb5987]

Microtech has a GREAT warranty service! The coil spring broke on my LUDT..mailed it to them, 8 days later it showed up at my house fixed,oiled,sharpened and a new lanyard put on it. They also sent me a "claw" patch and sticker!!! Amazing.

i would like to draw attention to the principles of the individual giving this demonstration. he on more than one occasion let his listeners know of his limitations while giving this demonstration. he also directed to a source that has more technical experience if one should choose to be more informed. this unselfishness is refreshing to hear and see.

[@dougheclipse1717]

The spring rests when in or out only gets real tight as you engage or disengage the blade. That's part of what makes these knives so good

[@1701spacecadet]

The blade can easily be removed. That circular pin near the base of the blade is a stop pin that runs in a slot. Remove it with your fingers or a small strong magnet and remove the blade out the front. Just remember to put the pin back!

[@cfltitan]

Yeah I laughed when he said that. If the thing was assembled then there’s obviously a way to get it out. They sure didn’t forge the handle around the blade. 😂

[@MrPickycat]

It's such a beautiful design. What clearly goes unsaid, is the amount of engineering and consideration that goes into the materials, and manufacturing processes of these knives. It's like art..

[@thomassharrow1883]

Great job. Your video makes me feel much more confident for when I have to take my Ultratech apart for maintenance. Thank you for providing this information.

[@jdmac44]

Funny, they don't want you to open the knife...but they'll sell you the bit to do it.

[@johnrice1943]

THEY KNOW

[@zachridgway7416]

You have a few things incorrect. I want to help you understand a couple things. The top tab-lock only controls the movement of the blade in the retraction. It keeps it from retracting unless the switch is pulled back. The top tab does not keep the blade from deploying. The rear tab-lock only controls the blade in deployment. It keeps the blade from deploying unless the switch is pressed forward. The rear tab-lock does not keep the blade from being retracted. The forward tab is not moved out of the way by the switch or the carriage when the blade is deployed. The design of the locking system on the blade allows it to move over the tab - kinda like a spring-lock on a fence or a retractable electrical cord would work. The blade itself is what moves the tab out of it's way. This is the same way, only opposite for the rear tab - when the blade is being retracted. So you do not need to manually move the front locking tab out of the way when trying to deploy the knife while it's apart, the knife will pass over it - and same for not having to manually depress the rear tab when retracting the knife while it's apart. I hope this helps a little bit.

[@Joeak74]

Always 'derail'/ de-clutch the blade before disassembly. Rem oil is a nice light body oil, and works great on any OTF.

[@appalachiangunman9589]

Rem Oil is the only thing I’ve found that will work on my Ultratech. I used two different kinds of Lucas gun oil, and some Hoppes oil that may have been for fishing reels but I’m not 100% sure. All three of those stopped it up and it would fail to fire nearly every time, despite only putting a couple of drops at the tang and wiping off the excess.

[@asznam]

The blade actually can come out, you just need to remove the pin that holds it.

[@sherman614]

Oh ok cool! Thank you, I wasn't sure.

[@megatrolltrollington]

I was looking for this. I was thinking, if the blade can't come out, how did they get it in there? Didn't make sense logically.

[@erikdewane3319]

Thank you very much! Your 'terminology' was just fine! 😊 Per chance, do you remember the distance between any two prongs in your 'screw removal tool'?

[@spacerothstein1381]

Whoa. I think it's different than the combat troodon, which I have only disassembled once quite a while ago, and is the combat troodon different than a regular troodon? Fascinating. Good work jumping on the grenade for us and filming it. Righteous work man.

[@jun1orbaitor44]

Im curious of this myself! Just got my 1st Microtech: The $802 Combat Troodon Mandalorian edition M390 (more like $900 after tax and shipping), and honestly, i feel i overpaid by $300-$400. Not super impressed for the price. Came with a generic cardboard box, clear plastic bag, advertisement and card saying it was inspected by someone that scribbles their initials! No bag, no cloth, no special cardboard outer box even. But i did order from Blade HQ, so i know it's 100% legit! Anyway, curious if the internals are the same as well. I just got my screw bit, so i guess ill find out here shortly, when i decide to do exploratory surgery!

[@Trippsy05]

@@jun1orbaitor44 Well the regular Combat Troodon is about $500 I believe, so roughly $300 - $400 of that was in the special edition paint and such. The regular versions of these knives are meant to be used and used hard, so they don't come with anything special like a bag or cool box. I myself just bought a Kabar and it came in a standard cardboard box with a plastic bag and a piece of paper. Doesn't take away from the fact it's a great knife that is meant to withstand the worst of the worst.

[@jun1orbaitor44]

@@Trippsy05 You're reaching by saying $300-$400 is for paint, the same paint is available on lower end models that sell for around $300-$400. I've bought dozens of medium end knives, never a Microtech before this, and im personally not impressed. What i paid for was the M390 blade, that was what the price bump was for. But $300 more?! The button was very slightly loose when i 1st got it, as well as the blade being very slightly wobbly, very slightly. After a month of playing with it here and there after work, the button is super loose and the blade wiggles now. To make it even better, MT uses a proprietary screw pattern, so i had to order a special tool to just be able to lube the action! And if you want a MT branded tool, its not cheap. I paid $20 for an Etsy off brand one that's about the size of a 1/8"- 1/4 square drive socket. Ive had 2 Kabars myself, and the packaging is almost identical to this blade, except Kabars come with sheaths! AND COST 1/4 TO 1/8 OF THE PRICE!! I also have Civivi's, Boker's, Kizer's, an Esee 5, CKRT's, TOPS, Mcusta and lower brands like Schrade, SOG, Ontario, Cold Steel, Gerber and more. They range from $25 to $350. They're made from steels between 1095- S35VN, and a couple M390's. I know low to mid grade knives, with a small dabble getting into higher end. This Microtech knife i got was overpriced, by a decent margin. This is a Special Edition blade from a high end manufacturer, it isn't meant to be used hard. It's a Collector's item and should've been packaged as such. Yes, it still can handle major abuse, but the point is this specific model or line is a Collector's item, so dress it up, especially when there's no difference from models that are $300-$400 less except the blade steel, in which case those lower models still have expensive "super steels" as their blades!

[@zachridgway7416]

Another point to help explain what I was trying to say is, if the thumb switch moved the forward tab out of the way of the knife for deployment, then the blade would not be locked into place when the switch is in the forward position. I.e, If the forward movement/position of the switch actuated the forward locking tab during deployment, if you were trying to stab into something while using the switch for thumb-grip (common technique), the blade would retract with forward spring tension on it, likely not having enough tension to penetrate the target. (Like keeping the button depressed on an auto). The switch should remain at the forward position when the knife is deployed. Pressing the switch forward with the knife deployed shouldn't change anything. You probably already know these things, but the video seems to show otherwise or that the point was overlooked at the time. Regardless, good video and knives. Keep up the good work.

[@waoooh]

“Be careful with this it IS under spring tension” proceeds to hold his hand in front of the blade at every opportunity possible

[@dougheclipse1717]

Good thing it's really not under tension lol. The spring rests when in or out only gets real tight as you engage or disengage the blade.

[@Crazy_Joe_Davola]

There’s a quick tip for when you wanna take apart your otf knife launch the blade and hold it when you retract it back and it’ll come off track and the spring won’t be a issue on holding the handles together when taking it apart

I finally got an Ultratech and enjoy it a lot but hate the newer screws which make it real hard to make a custom bit to take the knife apart. Someday I will take mine apart thanks to your helpful video.

[@artrozenbaum2367]

Can you please post a link to the juju13 video that you mention at the beginning. I haven't been able to find it.

[@fleetwoodray]

Sherman, last year, a HALO V owner on a knife forum was trying to sell his knife that he only had for I think less than 6 months and had a mishap where he thought the spring was broken. He was suggested to fix it himself instead of sending it back to Microtech for a spring since they had a bad reputation of taking forever on servicing warranty issues. Dont remember if he broke the charging handle or if it was a defect, but he ended up having to send it to Microtech anyhow. They ended up replacing the charging handle assembly which included half of the knife, making his look mismatched since it was a camo finish. Ended up costing him I think about $260 all together. So, the guy ends up with about $800 into that knife with now it being half camo and half black and the warranty was void. He tried to get I think about $400 out of it but it never would sell. I would suggest never to take them apart. I sent my Makora II in for a new spring and it took about 3 wks turnaround. Not too bad since it was right after the Shot Show last year. Semper Fi

Hey thanks for sharing! I've had the scarab now for over seven years and just love it! They don't work too well in sub-zero temps though, but what does? Anyway, it's kind of nice to see the the mechanism works identical to my old Italian-made OTF knives. Looking forward now to opening it and doing some well needed cleaning.

[@siemensbottenherr1359]

perhaps it's due to the thermal shrinkage of the metal components when it gets colder but that's just an educated guess

[@eonbree8593]

wow this really interests me. makes me wonder what else could be accomplished with this type of system. mabye with a strong enough spring we could make a semi auto airsoft handgun without using the power of co2

[@ryzen4368]

it would be insanely hard to pull the trigger but yeah its probably possible

[@shmutube]

Thank you for showing how the hell this thing works! Seems like the "core secret" is a spring that is in compression when the blade is in the body, and under tension when the blade is out. Plus some pretty darn clever mechanical features for safety.

[@bartlebaugh1998]

To remove the blade you have to pull the silver pin out from the bottom of the knife and then push the top lock in and pull the blade out

[@harryberry474]

Are those tapped screw holes that hold knife together just tapped into the aluminum handle or are they threaded steel inserts in the handle?

[@patricknel516]

To be honest, I understood you a lot better than the other guy ;-)

[@tory6733]

The spring under the firing button is to prevent rattle as the button would wiggle loosely without some preload. When you press the button to deploy the spring compresses and the button presses against the body. It does nothing to prevent drag.

Spring loaded stuff like auto/knives, and oddball firearms, where I am not likely to find replacement parts, I will work inside a heavy duty freezer bag to catch the flying parts. That is NOT a tiny spring. See the detent springs in handgun safeties. Those are tiny springs. They make extractor springs look big. The last gun I had in pieces that factory closed 15 years ago, so spare parts are mostly not out there, unless you know your guns really really well. Why does Micortech have almost 20 different fastener heads? That's $500 for tools to take the knives apart! Yes, it's a $500 knife, but.....

Watch the video made by Microtech themselves. The guy puts the nozzle from a can of Remoil in the front and just hoses the whole thing down until it’s coming up out of the opening. Then he shakes it out and wipes off the excess abs that’s it. And that’s right from the manufacturer.

[@fredminpin]

I would be kind of curious how much pressure one of these knives could take before the blade would snap out, for instance Cold Steel does videos hanging weights from the knife in a vice to prove the strength of their locks and pins, which is amazing, because I wouldn't think any knife blade hanging out on pivot or tang of approximately 1/2 to 1 inch would be that strong or good for much? This is also one of the reasons that I didn't notice or give the OTF's much credit over a flashy or show knife, but it sounds like some people actually carry or use them (where they can).

[@cfltitan]

They’re not hard use knives. They’re more for just general EDC stuff like cutting boxes and rope or whatever. They’re also, especially the dagger edged ones, self defense weapons. These aren’t knives you want for trekking out in the woods or in a survival situation but in reality no folder is. You’d want a sturdy fixed blade. That’s why even though I ALWAYS have a nice folder or my Microtech in my pocket I carry my ESEE Izula 2 as well in a horizontal cross draw setup on my weak side.

The hole on the side of the firing handle is to reduce sliding friction i would assume.
