How to Design an Unpickable Lock
HTML-код
- Опубликовано: 19 дек 2023
- Welcome to an exciting journey into the world of lock design! In this video, I dissect the flaws of traditional pin and tumbler locks, exploring the vulnerabilities that make them susceptible to picking. Join me as we delve into designing a lock that addresses the challenges of both security and manufacturing head-on. Who knows? Maybe we'll end up creating something truly unpickable.
The few quick clips at the beginning of the video are from the @lockpickinglawyer

That cardboard "manufacturing defects" visualization was a genuine epiphany for me as to why locks are pickable
Glad that it helped! I hadn't seen anything quite like it before, more something you would find in a manufacturing lecture
Yeah this is honestly the best way of visualizing it!
@@BuiltDifferentDesigns Just so you know, the design of your lock is very similar to the design of a person named Andy Pugh (who is under that name on RUclips). Just much simpler. I thought you might be interested.
Was a great way to show the theory behind picking
Same here, I never really understood the concept until it was demonstrated so effectively in this video!
Great use of CAD (cardboard-aided design)

nice

Lock Picking Lawyer: Hold all my beers.
He has to send him the lock 👍😎
Year that was my first thought before I even clicked on the link to his other video. I checked this video out before commenting.
Because in this video he references the YT channel *Stuff Made Here* who also made an "unpickable lock" that the LPL took down with a different attack than tension & pin manipulation. So I am sure the guy who's doing this channel is aware of the LPL.
So there's one to watch out for.
TBF being unpickable is easy -- every digital keypad is unpickable and you can just read a key with a digital sensor -- not having security vulnerabilities while being practical is what is hard.
@@simonrz It is tradition by now.

Locksmith here, there are locks that are EXTREMELY hard to pick.
The issue is price, people aren't willing to spend a hundred dollars or more on a basic lock. Not to mention installation, servicing, etc.
The more pins, the more something can go wrong.
Just one master pin can greatly reduce the pinning arrangements, I could make a "unpickable" at my shop. The issue is you wouldn't buy it, you might think you would. But you won't. People don't even want to pay for basic security pins, they WILL NOT pay for some hyper advanced lock.
We sell Abloy locks, extremely high quality obscene pick resistance for a few hundred. And we also sell commercial master locks with pretty trivial pick resistance.
We sell dozens of Masters a month, I've not seen a single Abloy sell in the last 2 months
Exactly, the main thing about economics is how to make cheap locks that are just 80% better at pick resistance without much extra cost.
I think that's where people like LPL come in showing how easily defeated common locks are. I ended up choosing a lock that while not expensive and not unpickable, requires an odd way of tensioning that would thwart most pickers. When I build my forever home and I have more valuable stuff in it, I will certainly be spending at bare minimum abloy price for my door Locks, which of course would be coupled with better hinges, hardware, doors and frames. I know most won't follow my lead, but I try to convince people of the value of security.
Isn't there also the issue that having a completely unpickable lock means if you lose the key you are going to have to break a window or knock a door down? Is completely unpickable really desirable? Really you just want something inconvenient enough that it's going to be obvious if someone is there trying to pick it...
aou could sotre a key with a good friend or a good hiding spot in the garden at least that is what i would do
It must be a cultural/historical/awareness thing too. In Finland Abloy locks are pretty ubiquitous. I personally happen to think that the main reason for this is the control of locks and key production via licensed locksmiths, intellectual property rights limitations for importing key blanks and the whole system where you have to order the key from the factory directly. The locks are safe, kinda pricey but people generally can't copy the keys. People who move into a new house generally don't change the locks if all the keys are still present and the lock is a fairly modern Abloy lock with patents still being enforceable and no licensed locksmith will go near copying a key or importing black market foreign key blanks. It's a trust thing and I don't think you can set up such a business model from scratch in 2024 and especially not in a country where no one trusts locks to begin with.
3:22 This is the best explanation of lockpicking I've seen.
The issue with locks is - they serve the same purpose as a seal sticker. They are a "no one has tampered with this" device rather then a "no one has access to this" device. Because usually you can just use a crowbar and bypass the lock. It's just that it leaves marks. There is very few need for something that cannot properly protect against someone getting in, but just makes sure they when you come back and see it you know no one has been here. Let's face it - the only time you won't know if someone picked your lock would be if they were very professional at whatever they tried to do behind that door. If your place get's robbed, it makes little difference to you if they unlocked your front door with a lock pick or a crowbar.
Yeah no, security is about deterring the most common attacks on the weakest link for as cheap as possible and not about seal stickers. You know someone has entered your house when it is in a robbed state. And you care more about preventing that then knowing that it happened.
You cant get through a metal door with a crowbar.
i mean, if your doors aren’t made of paper (like the US standard doors), opening them with a crowbar can be very difficult or almost impossible. next weakness is ofc windows, which you can put bars over (but probably don’t want to for residential homes) and of course, don’t make outer walls out of paper either. at this point the lock can actually be the weak point again
@@asdfghyterlol no
@@asdfghyter Breaking stuff is loud, which makes locks have a slight security feature. If they don't pick them they might be heard.

I’m surprised it took me this long to find a McNally reference
The first 3 minutes really helped cement my understanding of why pins "bind" - excellent video!
okay that taught me more about picking than I ever was able to grasp. 1:34 - 4:04
It taught me enough so that I can understand what lpl is rambling about when he is picking locks.
Hello you may have discovered this already, but with resin printing you will benefit from getting a small uv light off Amazon to further cure your prints after printing. It's possible that some of the sticking you're experiencing is due to the slight tackiness of resin that isn't 100% cured. Great video!
I have been a locksmith for 40 years -- the two cylinder technique has been patented by Corbin, and is known as master ring masterkeying. A similar technique was patented by Best - both were almost 100 years old when I was an apprentice . The false hole is also nothing new -- it is called a trap key cylinder. If you employ that technique, you have to have another way to open the lock, so you can free the trapped key or core.
That’s interesting. Do you know the patent-numbers?
@@malvoliosf I have replied twice, but something is bouncing my posts
@@willschmit436 Huh, well, your comment is appearing here.
@@malvoliosf OK - so you got my explanation, and three links (two PDFs, and one youtube)?
@willschmit436 Nope, do try again now that RUclips is allowing your messages!
Cost is the enemy of precision. Great demonstration. Thanks for sharing this description of single pin picking ;)
3minutes in and this is the best simolified visualisation i’ve seen on why cheap locks are pickable, regardless of “pick-proofing” techniques such as the use of spools and such.
More important than being unpickable, does it work at a wide range of temperatures as well as dust, moisture and dirt conditions? The fact that the conventional types are still on the market is an indication that being unpickable in NOT a primary concern.
As well as... If someone can't pick it and wants in they'll just break it either way.
Your explanation with the cardboard is the best intuitive way to explain lock picking I've ever seen :o
Finally I understand where it's latching onto and what "binding" means.
This is the best demonstration of why key way tension works that I have seen. It explained everything about picking that I have wondered about.
Thank you.
Very cool. I love seeing people's lock innovations. I totally agree with you.. its absolutely inexcusable that these lock companies are still making locks with vulnerabilities that have been well known for a LONG time .
At a guess, you could still bind the pins by applying forwards pressure against your cam plate, but it's definitely an interesting design! The thing about locks is they're more of a psychological barrier than a physical one. A glass door with a "NO ENTRY" sign is as secure as your inability to throw a rock through the glass. The goal is to encourage typical people to not interact with the locked item, and to be suspicious of atypical people who do anyway.
I dont see how forward pressure would bind anything if the testing happens after rotation. Could you elaborate
@@dark6.6E-34 remember the demonstration with the cardboard at 2:30?
imagine if he slides the cardboard left or right rather than up
Good points. Yes an active video camera definitely deters. So do bright lights as people want to remain hidden in the dark. You can also get cheap motion sensor alarms off Amazon and place them in the shed or whatever you are protecting. More barriers then they want to deal with. In my small town we have a problem with night crawlers stealing from yard. I always tell people the first best method is sensor lights which are pretty cheap these days.
@@wans3216 Ik, what the directions mean. But I realized from the demonstration at min 6-7 what the idea was. I am curious now if it works.
I feel like you’re correct here. A different guy recently made a similar “my take on an unpickable lock” video (it was great but I can’t remember his name) and I think his first design had the same vulnerability. He did…something with a spring at the back but I can’t remember what lol
I am an amateur locksport enthusiast, and I just wanted to say your cardboard demonstration at the beginning of your video was a good visual representation explaining how imperfections of the internal parts of a lock make it possible to have and identify binding pins so they can be "single pin picked" one at a time.
I watched a lot of lock opening videos and now I finally understand what they do and how they are doing it. Thanks
Great video, great idea!
Best thing is that it can work with “normal” keys and doesn’t need any special key copy equipment at locksmiths
I’d say make (or let make) a brass version and send it to LPL !
This was the clearest and best explanation of locks, and I’ve seen many of the other great unpick-able lock videos with their own great explanations.
I think this is the best way I've seen lock picking explained 👏
The best part about this design is that it isn't over complicated and doesn't require precise manufacturing
Amazing explanation/demonstration of how lockpicking works, that made it so clear
I always watch the Lockpicking Lawyer but I learned more from this in a few minutes :-) I'm slow. But hey, great! Loved it!
There was a really old lock that I remember Lock Picking Lawyer showing off that had something similar to what you came up with, only the "wafers" were cup shaped and if you got a false set then they would drop into recesses that would permanently jam the lock.
that was the best explanation for binding i've seen
That's a bit of BRILLIANCE. Definitely got my gears turning.
Good, I'm glad someone else had this idea so I don't need to build it. For seperating setting and testing I suggest using donut shaped wafers so they can fit around some inner pin which can then function as the key (height picked by number of donuts around it) when the core rotates to some other point.
Your passion is readily apparent. Reminds me of when I was green behind the ears getting into projects and stuff as a kid, just wanting to talk about and share them with others. It's refreshing as all hell. Subbed! :]
That cardboard "manufacturing defects" visualization is brilliant.
Well done! I subscribed right away to see where this goes next. I just realized this video is from 6 months ago. I will go look at your other videos and see if there is already an update.
Keep in mind that the cheapest 3D printers are usually not a good deal. You will usually pay with time, frustration, and accuracy. One thing to also keep in mind when it comes to MSLA printers is that the ambient temperature of the room can effect the final size of the print. If you need fairly tight tolerances, and you adjust your model to try and get the final print to work, printing the exact same model on a day that is even just 5-10 degrees hotter or colder could make the final prints no longer fit together.
5:02 hearing you say that was so satisfying!
This is one of the best idea and explanation on lockpicking wow I’m flabbergasted
the lego sounds when you were assembling the model was awesome
Hey I think this video is really great because you use big models and explain things really really well. Like, better than most engineers out there! I loved the demonstration of how to pick locks with the irregular pieces and the explanations of how your lock worked!
I had a similar idea to this (using a stack of wafers to make the heights discrete and separate setting from checking), but this is a MUCH more viable take on that idea. Very neat design.
You have to be the best informative and creative RUclipsrs i gave ever seen
3:15 BEST explanation i have ever seen. Ty
Very nice. I was pondering a similar design, but hadn't come up with the watchdog pin yet. That's brilliant.
Brilliantly explained. I think you nailed it. Great video.
Fisher price lock picking set.
I'd buy that for the kids!
Fantastic work. I would love to try picking it 🔓
Great design! This is possibly the best tweak to pin tumbler lock design I've ever seen. I'm not sure about how cheap it is to manufacture, though. Having core that needs lathe work, broaching and drilling for the core combined with drilling of the mid core seems potentially expensive. On the plus side, the looser tolerances needed for this kind of design help a lot with the price. I guess the biggest question is how many thin pin wafers you can use because that limits the number of "false gate" positions.
For example, if you can fit only two wafer pins per stack and use 5 pins, total keyspace is only 3^5 or 243 different keys. Not great because if this kind of design were commonplace, a thief carrying full 243 key set could open every lock ever manufactured using this scheme. And you could add a second row of pins but then manufacturing it gets very expensive very fast.
The design you used to separate set and test events was ingenious, though! All the other designs have required multiple actions by the user but this can do everything with a single turn, similar to disk detainer locks. I think a bit different shape for the middle part would be even better to avoid sharp angles in the cam mechanism but the idea is a good one.
Of course, this lock can still be decoded, just like every other mechanical lock. But if you use tapered pins for everything, decoding the lock will be tedious task.
I'm a bit sad that it took me this long to find this video. This is definitely a better design than the one I designed for my own pin tumbler variant.
The carboard visual where very nice, never had a better view of lock picking
You got to the important insight of this problem relatively quickly compared to most people who try to "fix" locks, which is that there is no actual way to decrease the total feedback. It's a mathematical invariant that you can't get around no matter how many or what type of physical mechanisms you include.
All that can be done is separating and diluting that feedback over a solution space that's either large enough or difficult enough to navigate to decrease the feedback's practical effectiveness.
Your solution doesn't break this rule. You can still pick this one pin at a time. But the discontinuities you introduced are efficiently placed between all the consecutive measurements that a picker would like to make. Meaning the picker has to be able to compare the core's total rotation between two unconnected states, rather than two that can be smoothly moved between. Doable, but much slower to test and requires feeling for absolute positions rather than just relative positions.
Most first attempts I see at pick-resistant locks are people going for "free energy" solutions, if you'll excuse the metaphor. Basically just doing things that move the feedback to different places in the device until they've lost track of where it is and just assume it's gone. Indirectly, these often distribute feedback over a wider area. But the direct approach of just chopping it up into discrete segments is so much more efficient.
He not only made an unpickable lock but also teached how to pick a lock
Wow! Great video! Keep up the great work! I learned so much from this
A) Great Video!
B) Friction? ->Grease, works for Most problems
I have never had to re-lubricate a lock before and I don't want to start now.
@@shoo7130 Practically all locks have long-life lubricants inside them. They don't typically need to be re-lubricated in any reasonable amount of time. It would be more difficult (expensive) to produce locks that don't need lubricants to function.
Needs a spool or serrated driver pin for the watchdog stack, to prevent bumping (that is, tapping with a hammer or something) that stack to the shear line (making the rest of the pick trivial).
My All Time Favorite - LockLab Founder - Bosnian Bill (now retired from YT - to our loss) encountered something similar to this outer-sleeve-core in his challenge lock series: (1134) Whipped: Ray's Nightmare Challenge Lock
This concept actually defeated him for two days!
The back "watch dog" pin is a great improvement on the concept.
Can't wait till the next video! 🔥
Very innovative! I have seen a few people who have shared very similar ideas to this, and I do think there is a lot of potential with it.
One major issue I will say (and you touched on it) is if this lock was mass produced, the large amount of masterpins/wafers would cause the lock to fail and get jammed up often, especially in situations where the lock is exposed to the elements.
I would be interested and it would be really cool to see how well a lock like this would hold up after a few years in the field!

I know it's frustrating to see the same technology in locks, especially when they can be bypassed so easily in many cases. That being said, it's been this way for longer than just the last century and a half, but actually for a few thousand years when you consider warded locks, lever locks, and even the anchient Egyptian locks. This technology isn't going away, especially in today's age that has defined standards and rating for locks and door hardware that has been established and set over the last century and a half.
The best we can do is raise the expectations of the quality and effectiveness of the locks that are already in production. You would be amazed at how good tolerances alone can make a lock very difficult to pick... but on top of the good tolerances, if it has a paracentric keyway, high-low bitting, and security pins (especially when there is matched milling in the plug), the lock becomes nearly unpickiable in the field when done right.
I personally would love to see the overall standards of locks in NA go up. It is clearly a major issue when companies like Master Lock know about their security flaws and choose to ignore them since they know the general public is unaware and they will make more money that way...
I don't want you to think I'm saying that it's not worth the effort you are making... by doing what you are doing, you are helping to educate the public on locks and the security flaws of the locks that exist here currently. Also, if you were to produce these as commercially available locks, you should do it as your own high security company (similar to what Bowley and other major lock manufacturers have done). This is typically how lock companies have developed and grown over the last century. Even masterlock was known for better quality locks a few decades ago, and even produced their own high security lock (#19). As other high security companies were gaining success and masterlock had already captured the basic comercial market, they discontinued their high security line and refocused their development on cheap low quality locks since that's where the money was for them and they didn't care about the reputation of having cheap low quality locks. This is why they don't fix their security flaws today.
Looking forward to the next part!
Damn, I had this same idea after watching stuffmadehere's video, only with a different cylinder layout. This layout probably has mechanically simpler shear lines than what I had in mind, which was similar to his two-cylinder layout. Congrats on making this work! I would like to build one myself when I get the opportunity.
This guy is prob going to be famous soon
Pretty ingenious design. Excited to see a properly manufactured one being sent to some lock picking masters. It may end up not being any cheaper to produce than a simple electronic lock (which should be able to offer perfect picking resistance if done right) but an analog / non-powered alternative could still be very useful.
Was thinking the same. Found and used Abloy locks, but now days those are picked. Just when I started tinkering with my own solution, I found your video, and I must say I'm impressed.
Plan to make the design "Copy left - creative common - open source"?
I think that the reason that most locks are very easy to pick is that the simplest and most common method of bypass is and always will be physical force. Lock picking requires some level of knowledge and skill and while it's easy enough to learn these days historically it's been a much more rare skill. Even in modernity the method professional lock picks use is to destroy the lock with a drill.
SOME ONE FUND THIS MAN HE'S A GENIUS!!!
I had pretty much the exact same idea, but i lack the 3d printing skills to actually test it.
I have one major improvement suggestion. Having a full middle core is a lot of material and take a lot of space. Instead you can use a small block just above the inner core. If the call the rotation plane xy, inner core would push the block in the z-direction after turning a bit and only if the shear line fits is it able to push the middle block and complete the rotation. This also eliminates the need to protect against binding the core to the middle core, since they now move in different directions.
Really cool lock and also a great video!

Great instructional video
Great video, great idea!
Best thing is that it can work with “normal” keys and doesn’t need any special key copy equipment at locksmiths
I’d say make (or let make) a brass version and send it to LPL !
Also if there would be a way to retrofit existing locks with these enhancements, e.g. replace the single cylinder with the double one, that word be epic 🎉
Your design is similar in concept but quite different in execution to Tim Hutt's design (I'm guessing from your other comments that you've seen this one) - with yours potentially being more manufacturable.
One possible vulnerability would be to shock / vibrate the lock in order to jiggle the pins while applying torque. It would be an interesting challenge to design a mechanism which decouples the inner and outer cylinders if the lock is bumped - I think it would be possible, and it would force you to reset the lock if you tried this sort of attack.
As an aside, you've done a really good job in the presentation and pacing of this video - subscribed, and I look forward to seeing what you come up with next!
Yes! I have seen Tim's cross-lock. Almost the exact same core principle. I thought his push-in-then-turn concept was interesting for sure. How to ensure the selective torquing of the testing is one of the main challenges with these designs. I decided to target a standard keyway with this design.
As far as your suggested vulnerability you are spot on. I haven't been able to test it but I agree that a shock attack may prove effective. I will talk about this vector and another in the next video.
I had similar design, but the issue is, that you could have a blank key, that lifts all wafers to the top, where it creates shear line with wafers. Better design would be to have master pin with slim part that accepts moving blade at some point to test all master pins height. Similar to a bar in those rotating locks with plates and hey with angled notches (sorry forgot the name) that have gates, false gates etc. Those also can be utilized to create such unpickable lock.
If the pin stack isn't tall enough to fit the pins like that, then it won't work. You can only comb-pick like that if the pin stack is manufactured with enough empty space to fit all of the pins above the shear line.
I really liked you watch dog idea. I think that distance should really help with bumping attacks as well.
An excellent visual demonstration of how lock picking works, and related to pickers language, binding, counter rotation etc. Could also an answer to an unpickable lock be using electronics where there is no manual backup method of entry, such as, a key. Maybe, a secondary circuit with a separate power supply to act as a failsafe system should the primary electronics fail.
Still seems wild as heck to see anyone consider a flat pin tumbler lock as anything but a childs toy.
If I had a nickel for every RUclipsr with an unpickable lock I'd have three nickels, which isn't a lot, but it's more than two!
The two in question are "Stuff Made Here" which you already mentioned and "Works By Design" who just revealed a second version.
Yours is definitely the simplest version I've seen so far.
pretty neat idea
Welp, time to hound the rest of your channel for an update I guess.
I want to see a refined and finished product!
Reminds me a bit of the Andrew Magill lock but with a diferent solution, nice :)
I would like to come with a name recommendation of “The watchlock” named after the watchdog pin. just a small thought that crossed my mind and I wanted to share it here
In 1972 or 73, I saw a demonstration of a lock that used a set of magnets to unlock it. The key was set in a prescribed place on the lock body and if the correct set of magnets was in the key, the lock opened. There was no turning of parts. The only thing that moved was the shackle if the correct key was used.
Brilliant!
Looks like you used Kwikset for the keyway and blank (maybe even the pins and springs).
To make a 5 pin prototype version that is (mostly) metal, you could use a 6 pin Kwikset and the end pin can be used for the watchdog. You would have to make some modifications, but I think it might be feasible. Some metal rod can be drilled through to make the part that encloses the core. You would have to bore out the outer shell of the lock to accept that double core. But for prototyping, this might do the trick.
Great idea and it is only slightly larger than a standard lock assembly. Shane's lock was much bigger. I'm sure lock manufactures will balk at the idea because so many door handles and knobs are already sized for the industry standard lock core. Wouldn't want to mess with the supply chain.
great video and great idea, this looks like it could be easily manufactured with "conventional" tech, allowing for lower costs (if there were companies trying to actually be innovative...)
I thought I saw some issues with the wafers design, but on a second look it seems really solid.
Great job!
I once heard " Nothing is unpickable. You just need to have the right tool and need to know how to use them"
I can't remember where I heard it but it's true.
Nice work!!
The "watchdog" circle should be on the front of the lock in my opinion, because it makes it 100 percent sure to prevent picking if glue is used to bind the cores.
I AM HERE FOR THIS UNPICKABLE LOCK CONTENT!
but it doesn't count without a locker picker
that's a very cheap but also effective way on how locks are picked on 3:00
love this
So you basically pick the inner core, then when it does not rotate all the way reset and try different combination.
So the unpicability depends only on the number of washers in each pin. With only two it is pickable i think in under 30minutes.
Saw this in my recommended and I hear "this is the lockpicking lawyer" and I'm hoping he gets ahold of this
Have a look at the Bowley locks. Simple parts and hard to pick. Needs very special picks and lots of time to get it open. Costs a couple hundred dollars though. I bought them because I liked the shape of the key.
They're definitely hard to pick, but it's still possible to pick them one at a time. The lockpick uses 5 picks at the same time, side by side. Also the lock itself doesn't function like a normal lock, which means that there's a learning curve on how to unlock even with the key. This lock, you can use a standard key *and* standard pins, and I don't see a way you can pick it one at a time. It's simpler, uses the same everything, and is exponentially more secure barring some other exploit.
@@dave-kt7sj But the Bowley uses much less parts and easier to assemble. Yes it is pickable but not easily and you need those special picks.
@@halohms If you remove all the bitting, the part count is similar.
I've seen videos of the Bowley locks getting picked with a metal wire in a vibrating tool (basically slightly more advanced bumping and raking) in just a few seconds. Allegedly, Bowley was so certain they had a winning design that they didn't use security pins nor different tension springs to safeguard against that. I haven't looked back at them since then, they might have fixed the issue by now.
@@5467nick There are 2 security pins in my Bowley locks that I have and I bought them when they first came out. Nobody is going to pick my door with those locks - they will just break the glass. But that's what the cameras are for....
Loved you in iCarly!
Make sure there's a guard to keep the watchdog pin from getting shimmed!
If you have wafers of fixed sizes then that means that you can only use master pins which are multiples of that wafer thickness. For the two wafers shown in the cardboard example, that reduces the lock to 3 possible "heights"
Have you considered having the pins of the inner core default to the inner shearline so it rotates freely when relaxed? This way, anyone putting tension on the core will force a rotation and be unable to get any information about the binding of the pins.
It's a clever ideas, but I'm not sure that would be desirable fur this lock? If the inner core can free rotate, then the cam can easily set the watchdog pin correctly. With that set, that could possibly lead to being able to tension the mid-core, and then be able to do a traditional pick on the pins maybe? I think therefore you might want the cam operation to be hidden behind a pin setting procedure like his design, to add time to getting to the cam setting watchdog pin. But I might be wrong. Yours is certainly the kind of thinking and testing you'd want to try in the real world to find out which is better in reality.
@@mikedoragh746 Yes, once I'd finished typing and hit to submit, I thought it was an idea with some flaws. Still, it seems no lock is truly unpickable, it's just a question of making it as frustrating as possible. I think the top strategy should be to make it look like any common-or-garden lock and provide any picker with no additional context (just like they would face in the real world). Don't even tell them there's anything special about the lock. That would make a truly fascinating picking video as they discovered what it was that faced them.
Use some graphite to help with friction
Good idea. I tried some tri-flow but it didn't seem to work well with the plastic.
I like your solution, little secret "you can break every Unpickable lock"😃
Yup it might not be extremely fast or easy but it will break
Thank you
Great video, really intuitive explanation.
I think turning this from brass and a knee mill would have been faster and cheaper
