The only lock I use to protect my property is a head lock. If that lock fails, it's on me. Haha JK. I just keep a gun handy at all times like a real Amurican. In all honesty tho, he does make me a bit paranoid lol I can't just sit at home like a hermit on all my belongings like a hen on an egg, gun on my lap, chugging coffee, and twitching at noises in the dark. I mean... I _could..._ but no. I'll just use locks like everyone else and hope my treasure is still there when I get home.
@@DanteYewToob "...I can't just sit at home like a hermit on all my belongings like a hen on an egg, gun on my lap, chugging coffee, watching FOX News and twitching at noises in the dark." There, I fixed it for you.
@Maestro.Hu1k You don't want to be as hard as diamond. Then it'd be easily breakable with a hammer or even a decent sized rock. Hardness and toughness are usually opposing qualities, to an extent.
I am wondering if it would have been enough to make 1 cut in the bend. That way maybe one side could have been lifted up far enough to create some space to release the chain.
Some interesting factoids I thought might be interesting to share here: Boron Carbide is the material used in trauma plates, which are the armour inserts used in modern body armour. Its Vicker's hardness is 38 gigapascals. It's the third hardest known substance. Something interesting to know about "hard" objects. The harder something is, the less it can deform before it will fracture or shatter. Its yield strength and tensile strength are very close together. Glass is very hard, but it will shatter before it can deform very much. This is partially why body armour isn't just plates of boron carbide. Aramids(like kevlar) are not hard. They have a high tensile strength, but they will deform easily(you can deform kevlar with your hand, by folding it). Thus, when a rifle hits an armoured vest, the plate will absorb most of the shock and shatter, and the fabric vest will catch the fragments. In theory.
Good point about the yield and tensile strengths. This is shown with the boltcutter jaws not shattering but being deformed slightly while the shackles quickly snap. Many lock and chain manufacturors advertise their products as having a higher Vickers/Rockwell strength rating than the best bolt cutter jaws. But as we see here, that isn't an effective method of protection. The best you can ask for is that most thieves will be defeated by these locks and the ones with hydrolic cutters/angle grinders will be stuck for a long time in a vulnerable situation. A good balance between yield and tensile strengths would force a thief to work for a long time to succeed. Something they don't want to do.
@@iamdave84 If the Vickers/Rockwell rating is higher than the boltcutter jaws, neither will be cut by tht boltcutter. If not, then the chain is usually more accessable to the boltcutter. With two loops of chain and possibly a high schackle shoulder on the lock, it is difficult to get the boltcutter jaws fully in position. Therefore, take some time to find chain with a rating of 50+. Mining industry tire protection chains are a good source. See Pewag and RUD.
Ahh simple truths that have shaped technology through history. The japanese Blade is another such tale: contrary to popular misconception the quality of Japanese ore was probably no better, and quite a bit worse than a leafspring from an F150 Ford truck... What made the Japanese sword fantastic was the balance of "hardness" and "softness". Designing the two properties together to make for the ultimate combination of tensil strength and hardness.
I love how you deliver on what you promise in a video. Show lock, explain lock, open lock. No unnecessary filler. It feels like you value my time. Thanks.
What's incredible is we know it's going to go that way every time, and we just keep coming back. "But it's a *different* lock this time." Hell yeah it is and my body is ready.
@@8thlvlMage it isnt the destination, it's the journey - confucious Yeah. The journey is the same as well, just however long LPL decides to take explaining the lock before shaming its creator
If you really mean to enter somewhere and have the time there's virtually nothing that can stop you... Im a fabricator and often people want to build the biggest window protections... Even if you put a 1 inch solid bar its not a challenge for a cordless angle grinder, or a torch. Even if your house doesn't hace any windows and has a perfect door, if someome really wants to get in breaching trough a wall ain't that hard lol
thats often why the point of security measures isn't thief-repellant, it's more-so how much of their time you can waste before they do, inevitably, find a way through thief-repellant is a baseball bat to the skull
I don't know why I keep watching his videos. I haven't used a lock or a traditional key in years. My car is remote keyless. And almost all homes in South Korea use RFID/keypad combinations. Yes, I'm sure he could just walk right in with a big magnet.
I love how he doesn't express upset that the locking mechanism opened from the shock cause with that amount of destructive force the fact that it opened doesn't even matter, and that he still praises them for being ahead of the rest of the competition in this regard.
@@dragonslaya8851 hey that's actually a great topic; how much energy does it cost to open this lock and translate to the equavalent kinetic energy achievable by a sledge hammer for example.
*Next up:* "So here we have Master Lock's new M-9000 armored model, let's see how it resists to an anti-tank shaped charge" _shoots rocket_ "OK so we did get in relatively quickly..."
@@noahway13 If you're referring to the pick Bosnian Bill and he made. A company got permission to sell them and sold out incredibly quickly, so...a lot of people have that lockpick now. (Edited cause of phone autocorrection)
Those cutters put out 12 tons (24,000lbs) of force. I was apart of the marketing team that designed and first sold these cutters. They are actually hydraulic rebar cutters. We made these cutters, aswell as a smaller design the YQK-70 with its chassis used for wire crimping. The small version can put out 12,000lbs (6 tons) of force about half as much as the rebar cutter. You can get a mini one to put in your pocket, and change out the crimping end tool with the rebar cutter end and get a small concealable hydraulic mini bolt cutters. We eventually after several prototypes, sold the patents for the rebar cutter and wire crimps to the Chinese.
Great information! So 12 tons! I believe they would be capable of cutting up to 14mm molybdenum or boron alloys although I suspect it would have more trouble with proper heat treated case hardened shackles. I know manual 42 inch bolt cutters have a max rating at 16 tons and can cut anything up to 16mm, after that the screws and the jaws just bend
Used these when my job trailer was cleaned out by thieves, they didn't mess with the locks, they went straight to the hasps and probably had little resistance cutting those. Most lessons are learned the hard way
"See back in military school, we used to open the master locks on our lockers with our minds. It's actually a really efficient technique, but I doubt this is any cause for concern for Masterlock, as I am the last known master of this forbidden art, and I'm not really in the game for any more disciples."
In defense of these locks, they are quite rust-proof. I've had 4 of them (all keyed the same) on wood gates around my property for the past 10 years and they look and work as well as the day I bought them. They open and close smoothly in any weather conditions, and I've never had to lubricate them. I would say they ended up being the right choice for my low security application.
@@davidhenderson3400 Too late. Fronious already makes a cordless stick welder that would burn through just about any lock shackle with some 6010 rod or even more with electrodes designed for cutting.
@@semajniffirg230 You can home make such a set up with just a couple of car batteries and jumper cables. People have been doing that for years. I am surprised such a set up is being used for locking cutting all over the place.
What different people have been wondering about lately. Normal people: I wonder what I should do on the weekend... LPL: *I wonder just how tough master lock’s boron carbide shackles are*
you must not have looked very hard, I see them for $70 on eBay he compared them in price to a 42" set of bolt cutters, those have never been that cheap either
I love watching your video's. Thank you for all your time and effort you must have put in to these. I imagine you being just as good as a lawyer as a locksmith. Much LOVE from, CANADA niagara falls
Those aren't chips, they're gashes, or wide cuts. I paused right when he said that to see how many had commented about it. Really weird that he under played that to oversell the tool.
@@MuscarV2 But they're replaceable. The tool itself is perfectly fine and is effortless against the 2 smaller locks. He underplayed it because it's not a big deal with parts that only cost 20 dollars to get another pair.
Even broken blades can cut through multiple locks. But yeah they definitely need replacing now but hey its only about 20 bucks to replace those blades.
@Christopher Tysen Henriksen are you trying to say Harbor Frieght has ESP and can tell you are buying their product for evil intent? Why would Harbor Friegth deny anyone from purchasing their tools?
Nearly everything can be viewed from both a malicious and a benevolent perspective. The instructions that came with your toaster probably indicated that it shouldn't be submerged while plugged in due to the risk of electric shock. Sure, you could view that as instructions on how to kill someone. Or you could take it as a warning of how to protect yourself from the violent urges built into the toaster.
Nope. He's examining and testing various threats to common security systems. Cyber-security experts and mathematicians do this in their trade papers all the time, and nobody says they're training hackers. It's a necessary part of continuous security improvement. More generally, security systems that depend for their security on attackers not knowing how they work (aka "security through obscurity") are the least secure of all. Sure, they can be highly effective if nobody knows the secret, but it only takes one person to figure it out, and then everyone's security is *gone.* The best security systems are the ones that are effective even when everyone knows how to attack them. That's how modern cryptography works. Everyone and their mother can go and look at how they work but they're still pretty much impossible to break without compromising three system at one end or the other.
The thing is this, if you’ve properly sized the lock shackle and hasp there will not be enough space to get that style of bolt cutters around the shackle.
thing is though, when a lock is actually locking something, that something may impede being able to get such a large cutter to actually go around the lock as needed to do this.
Actually, I think they actually work better like this, because it causes a rupture by pressing in two points, like scissors. If they align perfectly, you would get compression force between them and surely bigger force to create a crack like that.
I would be worried about the very large lateral force on the blades. The way they are shaped, pushing them together when they are skewed like that is putting I guess maybe 15% of the force sideways. In that direction the blades have much less support and could easily shatter.
i'd be interested to see how they fair when attached to something like a garage door where it's unlikely you'll be able to get the bolt cutters across the shackle like this.
it would actually be possible to vastly improve the design by hiding wires inside the core. basically when the shackle is broken, the wires keep it together, while the damage the shackle did to the cutter makes cutting the wires difficult.
Alas, another excellent informative video. From real personal experience all locks used for denying entry through remote unmonitored ranch gates are just a silly prop. Unless a protective cover shield is employed to protect shackle from any type of cutter ( old school or hydraulic.)
If those are really laminated locks I'd like to see what those bolt cutters could do between a pair of laminations to just pop the whole lock apart in the middle.
2 wrenches will STILL break the brass piece that the shackle hooks into inside the body of the lock. As long as they use brass internals nothing is secured.
I'm glad I'd used the M15 to secure my cargo container that I shipped from the Virgin Islands. They have the bolt cutter imprints on them. And they still work just fine.
What carrier/shipping company did you use? I want to make sure I never have them ship any of my stuff, since they obviously don't take appropriate steps to protect their cargo.
If a thief wants to steal something bad enough, he will get it no matter how well you secure it. The idea is to make the theft as difficult, unattractive, and risky as possible. This way the thief will be less likely to target you and go after an easier target instead.
The main point of my motorcycle chain and lock is just to force them to spend a lot of time making noise under lights. God help them if I'm home, I have a rifle and can see the bike from my window.
As a non native speaker I think LPL's English is near perfect. His pronunciation is very easy to understand for me. I enjoy his English as much as I enjoy learning about locks.
@@AriaFromMahabre I guess he means that himself (Motor Borg) being a non-native, he understands LPL really well because he doesn't have a strong accent and speaks really calmly and articulates really well.
Grammar and spelling is important, at my place several mechanic shops lost their DOT license because of grammar and spelling mistakes in their inspection reports.
These videos only encourage criminals to try to break into your store, shed, garage or whatever. These videos also assume that criminals are going to carry these tools around and try what this person is doing in high traffic areas.
It’s interesting that the cutters are not built to prevent the ram from diverging from center. Although, apparently this cutter was still effective despite the misalignment of the blades.
I noticed that as well. If LPL had moved the padlock so its body rested against the cutter, the padlock would not have twisted so the blades would not have moved out of alignment. It did look as though it was 50:50 as to whether the cutter or the shackle would break first.
LockPickingLawyer I actually think that makes the cutter more effective. The ultra hard alloys in fancy lock shackles are brittle, and the offset jaws apply a shear force that no brittle alloy can withstand. That's why the shackles broke instead of getting cut.
Regarding the M15 wird breaking: As it was inside the boltcutter at an angel it touched the outer barrier (down right side in the video). It looks like there was so much pressure that it squeezed the ball mechanism on the inside, which seemed to be enough to push the piece out with the breaking force. Also (I think) due to the angle because of the already existing dents on the cutter, the break force was applied at the outer barrier of the bolt cutter.
Can you post a video of some Punk A$$ thief who after attempting to rob a place with a hydraulic bolt cutter, getting shot in the head by a "Not gonna take the BS anymore" homeowner. Might inspire them to get a REAL job.
I think the steel in conventional 42" bolt cutters is a bit tougher than whatever is used on those hydraulic cutters, those (hydraulic) are primarily intended to cut rebar which is quite soft.
well it depends on how "cheap" they are. checking amazon they aren't cheap but i might not be looking in the right place. side note: 11mm shackle is pretty small TBH, most decent bike locks have 14+mm and even high security padlocks like abloy 362 has 15mm, Multi lock (discontinued) has 18mm I'd be interested to see how these fair against some of the kryptonite locks like the kryptonite evolution lock LPL already melted, or the Abus rock, he already destroyed with the ramset. or others, but those are already destroyed so i don't think he'd mind trying it out
How much cheaper are they compared to blades that are actually made to cut steel? Also we would have to know how much longer they last and if they will be cheaper in the long run. QUESTIONS - AAAHHH
I prefer this line of padlocks for their superior weather resistance. 5 years riding around in my truck bed securing ladders and took boxes from a quick grab with cables. Lock bodies hold up to weather much better than older steel line. Still have to frequently lube the cylinder, but that's a given for an outdoor padlock.
You are extremely talented. I recently bought some Chinese locks to try picking then because they are cheap and Got them open fairly easy It got my confidence up to try a master M1 lock but I'm having much difficulty I've watched numerous amounts of your videos but still I'm not exactly sure if I'm Is lifting the pins properly or I just need to practice more any way keep up the good work and all keep Practicing
Simulation should be done in real world , i.e. try the above test while the lock is shackled on a gate or a barn while holding that hydraulic cutter , putting it on floor is not a luxury a theif will have
@dava, you wouldnt believe, a motorcycle was stolen from my street, it was chained up under the guys bedroom window neither him nor the neighbours which are terraced houses in the UK, heard a thing, they used a cordless grinder in the night, doesnt seem possible, but they did, the chain was still there of course!
Hey there LPL, i am constantly amazed at how seemingly easily you get into all these different types of locks... Not counting this video of course... But i have a question for you pertaining to a lock that i am constantly confronted with in my job.i work for a national storage and rental company. I am a building maintenence worker and am frequently asked to cut or drill locks off of the storage rooms due to no payment or folks losing their keys.. this sometimes results in damage to the room door or locking hasps wich i then also need to replace. Can you do a video or maybe youve already done one where you pick a schrowded disc lock... All our locks are these as we make tenants purchase them and use them... Thanks
LPL, you can prevent alot of the blade damage by having a precision Gib set made for the slide, to minimize the deflection of the wedge . As it is now the slide has too much clearance that causes the wedge-points to become misaligned, bind up and chip, the more force that's applied. Once the play in the Gib has been eliminated, it will not only reduce stress on the wedges, but will greatly reduce the hydraulic pressure needed to do it's job.
It doesn't matter if the blades are blunt, the shackle fails because of the shear stresses and not because it gets cut through, but you need some offset between the blades, so it doesn't just compresses the material. I don't know if it applies here, but for shearing steel a shear gap of 0.03 to 0.05 times the thickness is favourable, that means for the 11 mm shackle a shear gap of 0.44 mm or .017" would be appropriate.
Looks like Masterlock have pretty good locks for physical attacks, but bad for a more technical attack (like picking). Getting a cutter like this is likely easier/faster than learning to pick locks, so a more likely attack
I don't think we know enough to say things like "99% of thieves", because as far as I know, statistics like that simply aren't available. It's also easy, regardless of the reality, to form a picture of thieves as dumb and incompetent, because no matter what, most thieves who get _caught_ will be dumb and incompetent.
yeah, 99% is hyperbole, but it doesn't change that most thieves are going to just do a smash and grab because it's fast. they aren't afraid to be a little destructive to what they're stealing, either.
Well, if these are as easy to pick as the Chinese ones I have I think it's both faster and easier to just rake them open. Smaller, cheaper and lighter tools too.
Thankfully there are few applications where the shackles of these locks would be accessible enough for bulky hydraulic bolt cutters such as these. Entertaining "proof of concept" video, though :)
When I was just a kid, I used my dad's pincers to snap the heads off the rivets that hold laminated locks together. Once off, the bottom laminations were easily removed and then the core simply fell out. So in that sense, absolutely. I see on these particular locks today, the rivet heads have been recessed. 50 years late, but still appreciated. If the jaws open wide enough so that you can insert the lock body and split the laminations by busting the rivets, seems like a great way to defeat the lock.
@@picramide these locks are not laminated. The outer shell is stainless steel and is made to look like the old locks. LPL has a video where he takes apart this style of Master Lock.
Puppet 1995 Thus far, I’ve been able the split every lock body I’ve tried... they just need to fit between the jaws. But that’s not always the most reliable way to open the lock. The shackle can get jammed in place.
I laugh every time i see an LPL video which involves Masterlocks in the vid! I just know LPL will be extra savage every time he encounters a Masterlock! 😂
I don't think LPL shows the same level of contempt for Masterlock products as does BosnianBill. Seems that LPL lets Masterlock failures speak for themselves.
The padlocks rotating are applying a prying action on the blade tips, like trying to cut cheese while pushing down and sideways at the same time. If the lock wasn't allowed to rotate I think the blades would last longer and cut better since the sideways force wouldn't be applied to the tip of the blade as the lock rotates. When it comes to brittle materials, that initial bite matters a lot.
He has an issue with Master, because he's a Lockpicker/Locksmith/etc who is trying to educate the public about these terrible products from these terrible companies, and Master Lock makes way too much money selling absolute crap to the public.
No, it's just that Master makes crap and always has. I remember in the 1980s that in order to get into a locker with a Master combination lock all you needed was a hammer. One whack and it was open. You could even re-use the lock afterward. Though I recall another lock that just shattered. Master Lock has a well deserved bad reputation for easily pickable crappy locks when they should know better. Their Sentry safes are no better. Just take a circular saw to one and you're in within a couple of minutes.
Thank you for creating and sharing this video. Very informative. What type of padlock would you suggest then for something like a storage unit if not the ones above in your video?
My father always says. “Locks will never stop a determined thief, they are just a deterrent” “if they want it bad enough, they’ll get it”. Why I have a gun.
