Thank you for making this video! What worked for me with the leaf springs is laying in one at a time, putting one end in first, then coaxing the other end in with a 1/16th pin punch. I appreciate this content!
Thanks for the vid, seriously! I agree the hardest part, by far is the leaf springs. Here's what I did that worked for me, and I hope it may help others. Put in one side of the arm, place the leaf springs in position with the arm and the little ridge that is the center. Now, while applying pressure to the ridge/center area of the springs, place the 2nd arm. Take a small flat head, and guide the springs up towards the inside of knife while pushing down on the center ridge and 2nd arm. It will all fall into place. I do hope I'm explaining it well enough. I'm not saying this is the only way that works, just the one that worked for me. Hope it helps, and thanks again for vid.
Very good. detailed video to clean these knives and get them back in service. This would have taken several months if it were sent back to Benchmade. Mine is up and functioning like new again! Great video!
7:12 The leaf spring and arm assembly are the retention system. They are NOT what launches or retracts the blade. They are what prevents the blade from launching or retracting until enough tension has been applied to the main coil spring (really until the activation switch has travelled the appropriate distance). Once there is enough tension in the main coil spring due to the activation switch traveling far enough, the main slide trips the leaf spring and arm assembly, releasing the blade to launch or retract.
I agree and understand that the main spring is what is providing the force to launch the blade. However, what releases that tension is the arm assembly. Also in my experience when the arm assembly binds up, the main spring comes off the blade causing the blade not to launch or retract. I was trying to explain it as best as I could and in a way that most would understand. The main spring does not fail in these knives.
Great job on the Blade! Is the disassembly and assembly the same on the full-size Infidel? Not many videos out there for either one. Thanks for posting.
I found that I could use hot water into the knife to clean, spray parts cleaner into it, blow it out with a air nozzle, spray wd40 and blow that out and it works like a charm. I have had mine since 2010, had it rebuilt once from benchmade with a decent turnaround time (2007). Just had to clean it today and very decent tutorial.
Patrick Schiesser regular maintenance is definitely a good practice. A lot of guys don’t go through the trouble and we end up with their dirty malfunctioning knives in for service.
@@MattH-wg7ou Yeah... like I get in the moment it might seem it can function that way, but lube isn't supposed to only act like a lube for so short a time. You'd think they'd figure that out.
Hi! This is a shot in the dark here, but would you be able to assemble my Mini Infidel if I mailed it to you? Benchmade refuses to ship back OTF knives to non-LEO people, and I cannot find anyone locally who can do it. My knife is totally disassembled (it’s a long story), but I have all of the parts and screws. You would just have to put it back together. If you’re able to do this, please let me know. Thank you!
Are the so called leaf springs very thin Flat steel that you stack to create tension? You said twist leaf springs together? Pls clarify..found this very good video, just confused on leaf spring position....thnx for sharing knowledge...I'm in the fence on microtech or benchmade..the firing mechanism wise....
I have the mini and the full size. I rarely use the full size but it occasionally doesn't eject right and feels loose compared to the mini which is very tight and quick to eject but also very difficult to retract. The trigger slide is super stiff and difficult to move. Do I need to take them apart and adjust them? Glad I found this video because I've been terrified to take these knives apart lol.
Great demonstration! What if I have an HK Tumult OTF knife that jams and the spring keeps dismounting? Where should I send it? I'm usually pretty good at fixing these but this Tumult has me baffled. Thanks.
What size star head did you use. Also do you know the size of the screws. I know one side is bigger then other. I strip a few of them trying to use a allen wrench ouch
Steve Spencer the screws are T6 Torx screws...don’t have more specs than that...oh and you have to be careful, on the mini Infidel the screws are longer on the button side of the knife. Also on the mini, the clip screws are shorter as well. The full size version has the screws all the same size.
H Phillips I’ve had several Microtech knives in for sharpening and none of them have ever needed to be serviced. They all performed as they were supposed to. I’m no expert on these knives, but the Microtech knives do not fail like the Benchmades do...
My personal Microtechs are more sensitive to dirt than my Benchmades. But once you have the driver bits (tri-wings and domed tri-wings) for the Microtechs, I find them easier to service. The pin in the Benchmade activation slide is annoying. That said, the Benchmade feels so much nicer in day-to-day usage, so I still prefer the Benchmades.
Two years late to the party but mine was having an issue after a year of normal pocket carry. I took it apart and screwed myself in doing so. I shouldve thrown it in the ultrasonic and be done with it
Thank you for sharing. I have a couple of observations here. First of all, I really wanted to see how'to sharpen the knife. Secondly, the angle of the camera at the time you reassambly the knife is not the best, then, besides the challenging it is, we could not get the best view to learn. Nonetheless, I thank you again for making this video.
Chelan Wizard in sharpening several of these the main bevel ranges between 30-35 degrees. We add a 15 degree bevel to the back side to remove the burr. Another thing to note is that these knives are rarely perfectly symmetrical. It’s common for the to be way off from side to side.
Curtis Bennett never tried it but sounds like it might help. You’d have to be really good in the cleanup though. Don’t want crazy glue jammed in the knife.
What are you using as lubricant? I'm thinking of sending you my 3350 OTF mini what is the turn around time? P.s. It's missing one leaf spring do you have replacements?
Eris Free turnaround is usually about a week...we are a bit backed up now with the holidays. We do not have spare parts though. We currently use FrogLube.
This video made it super easy to breakdown and reassemble my infidel, thanks. Would you know where I can buy carriage replacement springs for the regular infidel?
David Metzger that is a good point...and that knife was actually disassembled after the video, dried up and reassembled. I’ve tried both ways with these knives, leaving them soaked in lubricant and running them dry. What has worked best for me is a hybrid of the two. I assemble them soaked and operate the knife a bunch of times. Then disassemble it and dry off the excess.
@David Crohn we have been using FrogLube recently. However, your preference of gun oil or tool oil will work just fine. Just make sure you do not leave it soaked as noted in previous comments. If the knife is left too saturated in oil, the oil actually traps or collects more debris (lint, dirt, etc.) and the knife will not function properly. I normally oil the parts while I’m sharpening the blade, letting them soak for 30-45min. Then wipe all the parts down prior to reassembly.
Strange that u think the leaf springs are responsible for deployment of the blade while staring at the large spring deployment mechanism. U may clean and sharpen blades for a living, but that makes it even sadder that u can't see how they operate
Tanner Ortiz is it loose like it just fell off track and needs to be reset? Try pulling the loose blade forward until you hear a click. If this is not what you mean, and you are referring to the blade wobbling a bit while deployed...then the screw that secures the carrier piece inside the knife has come loose. The knife has to be disassembled, serviced, and reassembled. We can do the service of you’d like.
It is... I've been trying to reassemble mine without removing the pins in the firing switch... I've tried every which way (including the way described in a comment above) and... no. I have to find a punch small enough now 🤦♂
I saw this advertisement on the internet today for a Benchmade 3300 infidel for like $100 is that for real I don't get it like is this some kind of joke is it made in China or something like aren't those normally like $500 knives how can they sell it for $100 I don't get it have you guys seen that you know what I'm talking about
Our turnaround is about 2 weeks. I think that’s quite a bit faster than BM. However, I do this as a side business so I do have to control how many knives I take in to keep backlog reasonable. Shoot us an email if you have a knife that needs work.
And oil would be a dust and lint magnet...why not just a little lithium grease with out the the hassle of oil ?but that means no more money to sharpen and fix the issue because of the warranty limited to 5$ to sharpen...dont get me wrong I love benchmade ...very well made knives but when it comes to sharpening the knife maybe mirror sharpened but I can get it just as good and to a mirror finish myself or maybe even better why would I pay you $5 to do that other than it would void the warranty to sharpen the blade I don't worry about the warranty I've got plenty of Benchmade out the front knives and had not one problem with getting any of the parts to fix it if it is broken other than a blade but then again if you're buying that kind of quality blade why would you be using it to to break the blade by prying on stuff but iv also dropped it and broke the tip....at d2 hardness???? The price is way to much for the actual knife js
Hi Shane, Overall grease (being thicker) should be used sparingly as it can build up its own junk and residue where oil will not. www.bladeforums.com/threads/white-lithium-grease.767450/ We get all sorts of knives in at different value ranges. Some knives cost much less than our sharpening but it holds a sentimental value for the customer and it's just a knife they love. We are here to help anyone who can't sharpen or repair themselves.
Can I send you my infidel for you to do this for me? I’m also armed forces and as you mentioned in the video, Benchmade is pretty bad about getting them fixed and sent back.
That's what he gets for buying an OTF. I have always said they are garbage and I will never own one. They have too many failure points, are high maintenance, and unreliable. A total waste of money.
Yes. The butterfly is in the wrong place on the clip for one. Anyone else spot any other irregularities? I'm surprised he didn't say anything in the video. This guy explains how to spot a counterfeit knock-off. ua-cam.com/video/xLYNmUqD6Rk/v-deo.html
Just sent mine back to Benchmade & they repaired,sharpened & cleaned
Wow just spent an hour learning the interworkings and tear-down trying to repair and this is all I needed to do. Amazing!

That mirrored edge looks beautiful.
This is an amazing Video thank you for posting it. Most people would send it to Benchmade’s awesome CS team.
Thanks for the information. I found that on placing the springs, if you get a set of fine tweezers, insert one spring at a time, it’s much easier.
This knife is not a full duty knife,it's self defense. Every tool serves its purpose. Use it like it was designed for and it will never fail you.
Thanks for speeding up the segments.
It is much easier if you put the leaf springs in first, and then just pull back one side at a time and insert the arms.

WD-40 is NOT a lubricant. So don't forget to add the appropriate lubricant at the end of your maintenance process.
@@error.418 I'm not saying this is the case with the OP. But the amount of people that think WD40 is a lube is crazy.

@@MattH-wg7ou Yeah good way to destroy an OTF
Well, I know this isn't a Microtech but they recommend spraying the inside of the otf with Remington oil and blowing it out with endust air can spray.
Great information and good quality I approve👍

I find that dry lubes like Hornady One Shot, or Finish Line Dry bike chain lube work best. Wet lubes tend to attract and trap dirt.
