Anyone know anything about Brifield C2 handcuffs?

Link for the handcuffs: https://www.amazon.co.uk/dp/B07HN8QLCD/ ... _lig_dp_it

I never owned a pair, but they seem similar to Kyung Chang and Yuil. The keyway seems more open, which makes me wonder about the seriousness of their security, since there's no keypost which would restrict the ability to fit picking tools (paper clips etc) into the keyway. They have a 3 pawl system which is separated by dividing metal. I am not sure if the dividing metal is all the way through like Yuil used to be, to where the 3-bitted key is required, or if the dividing metal is cut back far enough that normal keys would be able to operate.

Anyone have any thoughts or experiences?

buy a pair and then get back to us

Here is my overview video:

Interesting video and it is always neat to see something new.  Thanks for posting.

No prob. I do like them, they at least have the split metal plates in the proper places so that you require a key with the splits, unlike Yuil these days where you can use any old normal handcuff key. The quality control could be better though, for sure. Some have had no issues so mine may be one of a few less than perfect ones. Also the keyway is smaller than a normal key will fit.

Does anyone know if the make a matching leg iron? Quality and function does seem very similar to the South Korean stuff. Sort of resembles, them as well.

I am not sure but you could always ask the supplier on Amazon and see. It's possible I suppose.

Wish they were sold in the states. Id buy one just to check them out. Very cool key design. Its very bonowi-ish with those 3 separate key flags.

It is tricky to pick but I have managed to do it with 3 bobby pins bent and aligned right. I think the mechanism is much better than Yuil. Much better... If only their quality control was better because my pair's arms bend so badly due to sloppy tolerances around the boss rivet, that the end of the arm can touch either side of the cheek plates :(

Yea i saw your video showing the slop it had. Still looks like an interesting cuff. Some of the cheap cuffs come up with really neat ideas sometimes. There was one that had a wheel at the front of the teeth. It was some kind of anti picking wheel. I have only seen one pair like that in person. I wish the big cuff makers would make stuff like that, or something better

I wondered this too. With so many advancements why not improve? Clearly officers lives are at steak. Even Yuil with their current state, normal cuff keys work but they have extra pick protection and shim protection. These big known brands could add more protections.

The gotcha cuff was supposed to be (re?) invented to SAVE officer's lives. That was the primary reason for digging out Hiatt's design and adding a few extra bits. The business isn't around anymore. WHY, Profit and the all mighty dollar. Why improve things and have the cost go up when police can just shoot escapees  and if the prisoner is not dead, they get more time in prison for trying to escape. It's not rocket science. Profit is the problem. wars kill 1000's to gas prices down , and profit and dollars means that countries can kill journalists at will and know if what affect arms deals and trade.   No body (high up) gets a rats.

Sad. There's a cuff company in the US, or a mode, not sure which, which makes a cuff called something like Tri-lock or Tri-Secure or something, which is essentially a Hiatt cuff with Yuil anti-shim protection as I recall. Why are they not standard? I bet price is the main thing.

Interesting find. I agree allowing that much flexibility in the swing through action is usually indicative of a less than quality design. It's obvious some thought went into the engineering of these handcuffs. 

One thing I can not process is why no mainstream manufacturer has addressed chain binding. You can introduce the strongest, most intelligently designed, most tamper proof, highest security keyhole technology the world has ever seen but it's meaningless if your design can be defeated with an elementary level tactic that snaps the end points of the chain by a man with no muscle.

CTS actually does make "o" ring style handcuffs but in oversize models only. If they would put "o" rings in the trimax design and make some slight improvements, those handcuffs would probably dominate the rest. This model is attractive but again lacks any defense to chain binding. Yes there are hinged handcuffs and higher security designs but I honestly think it's time for one of these companies to reintroduce the handcuff with every security measure possible including manufacturing a model that will not succumb to bind.

of the 100,000's cuff sold each year, can you give numbers of incidents you both talk about. without numbers, there isn't a problem to be dealt with, just hot air.

While I’ve never performed the link bind procedure myself, and shudder at the mere thought of destroying a vintage pair of my handcuffs, I have seen this done on more than one occasion with standard linked cuffs over the years.

 Two cuffs that I can think of that wouldn’t be susceptible to link binding are the ADI Saf Lok available at the Discount Handcuff Warehouse and the single linked Alfa Proj Ralkem 992x series available at Cuffsland.

What is and what should never be….

Tuff kuffs came up with a great hinge and swivel. Its a great cuff but expensive. And ofcourse the one way swivel killed it I think. But your not gonna bind that up and break it and if only they built in a release or free swivel i think they would still be around.

Another question i had was why are they still messing with chain anyway? There are cables that are way harder to cut and even the kevlar cuffs. I have a set of ripp handcuff in kevlar. Fricken awesome cuff. I took a knife as soon as i got it and tried to cut it. I can tell you if it was a race between a hacksaw vs chain cuffs or a knife vs those, the chain would be cut way faster. Throw in the cut resistant cables and there is a ton of new cuff ideas a company like peerless could make.

Sorry meant " the grip" not ripp as the maker of the kevlar cuffs. Why cant we edit a post here. :/

The braided steel cable concept was often incorporated into bicycle locks as a lightweight means of deterring the all too common, quick bolt cutter snip. The former East German (GDR) leg irons also featured a braided steel cable and are highly prized by collectors these days.

These were said to be produced by prison laborers, and the hinged handcuff version with its aluminum body and nickel plated steel bows is one of my favorite modern collectable cuffs.

94104, if you look on my channel there's an Alcyon pair which have pretty much similar movement as chain but not as restrictive as hinged. I wonder how solid they would be against trying to snap it.

Even better! I was referring to their modern regular model, yours is even more secure as well as having that connection type.

Okay, I wasn’t even aware of this model until you brought it to my attention, but I see that they now make a cuff that’s quite similar to the S&W M-100 with a simplified universal joint type hinge.

The Alycon handcuffs are an interesting design but I ponder the strength of the pins and linkage between the handcuffs. This design should be resistant or binding proof but you would have to risk breaking the cuffs to find out. It's also baffling why a company can think outside the box for some of the design but not all. 

For instance, why not make this Alycon handcuff with triple pawls, pawl rails protecting from shimming like hiatts trimax, an internal lock that is not standard and that is more tamper proof than mainstream handcuffs?

I know cost can be a consideration but there's always something, just always something, that leaves good engineering just short of the finish line.

TK were an amazing design but the minute I saw a one way locking swivel I cringed. It goes without saying that is way too much liability for most agencies to absorb. It would be way too easy to break arms and wrists even unintentionally. 

Imagine if an intoxicated subject trips and falls and tries using their arms for some kind of leverage but ends up unintentionally swiveling the cuffs. It makes no sense why the engineering behind their design did not consider exactly what the op here said about free swivel and release options.

That's probably one reason they're out of business despite the design having some real potential.

For what its worth, I realize all the newest cuff designs say something to the effect that this newest design will save cop's lives, they tend to put the emphasis on the latest gimmick when in reality at least to me and based on many many years visiting prisons and spending time trading stories and escape techniques with cops around the world, the weakness is rarely the locking part or the construction, rather its the error on the cop's part.  Every time a cop has asked me, Michael (cause that's my name lol) what is the weakest part of the cuffing? I tell them its when you take your eyes off and drop your guard on the prisoner. If you are transporting, you have one eye always in the mirror watching the way the prisoner moves, is he doing something funny? why are his arms moving, why has he suddenly become quiet? 

The officers are at a disadvantage, they often times can't cuff a prisoner as tight as they should due to prisoner rights, etc and this leaves holes in the officer's safety open and the prisoners know this and that's when the escape happens and too often the injury or death to the officer.

I guess my argument is analogous to let's make a bigger more powerful gun to hunt deer with, why? a good old fashioned .22 is just as good at bringing down the game when used correctly no amount of extra gunpowder or bullet weight will really help if you can't hit the target.

So, yeah, the newest gimmicks in handcuff design mean really very little to officer safety, their safety is within them and their own instinct.

Excellent point, Michael!

Just look at what this prisoner did while left unattended handcuffed and wearing leg irons without the aid of tools or picks:

You know..

I disagree with that being a good example of safety awareness because those handcuffs should not have broken in the first place.. Yes the suspect was able to leverage the torque and force which caused failure but it goes to show you that just because the handcuffs are NIJ approved doesn't mean their design is proven..

I think it's time the NIJ advance their compliance testing of restraints because hinged handcuffs succumbing the way they did to this suspect is not only embarrassing but it surely sealed my fate with Peerless..

Peerless was never a great design anyway if you think about it.. 
Even with modern model improvements they still sport a single pawl, three teeth, are vulnerable to chain binding, and their hinged models are vulnerable to separation from rotational force. Popular or not, they are not longer my choice of restraint.

Just thought I would share.. 
A contact of mine reached out to the owner asking about the brand and other products.. this was his response..

My name is Julian, the seller and owner of Brifield.


This company is all me, but i have plans to expand heavily mid 2019. For now i just sell on amazon, but I am going to create a website mid 2019 and put a new range of different products on there, including many different handcuff designs.

Right now these are the only pair of handcuffs i have for sale, but these ones are very good quality and durable. Let me know if you have any more questions please.

And the price of £24.99 was just temp, because this product has only just came out i needed to drop the price to get some traffic, but the price will be going back up now im afraid.

Thanks Hex - I purchased a couple of these cuffs. They actually look nice with a subtle two-tone metal. I'd like to see the tolerances tightened up so there is less wiggle on the bow, but the price was right and I like non-standard keys. Will be good to see what he does in 2019!.

other countries don't have the handcuffing problems the USA has. I guess it has something to do with better training and better cuffs else where.  

To profit.

Must disappoint you. In many countries, American-made handcuffs are used. In many countries, self-produced handcuffs of standard design are used, but worse than American quality. Several countries use handcuffs of their own design, but the price exceeds $ 100.

Someone in Missouri is auctioning the linked version of the vintage Alcyon cuffs HERE. Since I have this cuff in my collection, I can attest that they do in fact have a free rolling star cog that engages the ratchet; the pawl is also split, and the springs are even stronger than those of the vintage S&W Model 90 cuffs, which should make picking them more difficult. Of course they still have the common 2 link/swivel configuration, so cuffing with the hands in front wouldn’t be very secure due to the chain binding discussed in previous posts.

Okay, I’ve since deduced that this is an eBay issue since it doesn’t occur with any other sites that I’ve linked.
Also, I’ve tried random Bay auctions and it happens with all of them.

As long as it isn't hurting me, I like it. Why not get paid by what people do any way? As long AS LONG as it is not collected, categorised and tied to an actual specific person who can be identified. If it's all anonymous "someone on this site visited this eBay link" then I think that is the Tao playing out. It does nothing yet leaves nothing undone.

I quite concur. If the Tapatalk platform owners are rewarded for increasing traffic to popular online shopping venues such as eBay, more power to them as long as my personal information isn’t compromised. Usually they just obtain OS and web browser identification just as most other websites.

In any case, it’s always good to run regular security scans.

These cuffs are manufactured by an ISO: 9001 Chinese Government 'Approved' Police equipment company in Jingjiang, mainland China. If you meet their minimum order criteria, they will stamp your company/brand name into the cuffs.

Interesting video, it's like watching Marcel Marceau do a promotional handcuff video. 
This review runs a little long as I try to be detailed.

I saw these cuffs on another website and decided I wanted to have a pair or two.  As things worked out  I purchased 2 sets of these cuffs on Amazon.uk by way of eBay [USA].  They cost too much for what they are and the bill was actually higher than stated however happy ending, cuffs arrived and Her Majesty's Customs didn't bother.  No Imperial Entanglements.

When I took them out of the box I was a bit underwhelmed.  They are unbelievably light.  I used a magnet to try and determine what was aluminum and basically most of it is.  The Bow itself showed a little attraction (stainless?) and the chain links were attracted at odd places.

This is the first cuff I remember where the dividing plates do reach up into the Bow and the Bow has milled slots to accommodate them.  Sort of screams out ‘Don’t lose the Key’ and, unlike Hiatts cuffs, each locking pawl has its own spring to hold it out.  Of course, the lack of a center post for the keyhole makes use of a pick (or 3) easier than a standard handcuff.  Key can be inserted from either side.
I am just going to go with the downsides as I see them; double lock lever is not square in the slot and you get the impression the key slides downward when engaging it.  The Pivot pin slack is very apparent in the video and the feel is worse.  The triple locking pawls look great in theory but are sloppy in application, Bows runs rough.  

I did what I call the Hiatts Multipawl Release Test on these and they passed easily.  What is that test?  You turn the cuff so the lock case is up (gravity is no longer your friend) and you put your fingers in the cuff and apply as much tension as you can to the Bow.  Then you turn the key and see if it releases cleanly.  Hiatts cuffs, if using a key with a short bit/flag may hang up and not release as the key may not catch all pawls and tension on the Bow and gravity will keep them engaged.  These have no problem in releasing.

I do run on about things so here is the final disappointment.  When opening the cuffs with a key, after all the teeth have passed each other.  In that last ½ inch before the cuff opens, both of my sets hang up.  I don’t know if it is poor milling in the ditch in the bow or mistakes in the radius of the entire body where the bow runs or something else altogether.
Someone up there compared them to Yuil or Kyung Chang and the feel is very similar.  Can they restrain you?  Yes.  Will any key even close to standard help you?  NO!  I guess that makes them High Security after all.

My bad, I failed to notice that the discussion had largely  moved on from the Brifield C2 handcuffs (like 3 pages ago.)  I just got mine and wanted to say that those cuffs are what the previous post is about.

Nice. They are not bad, especially from a collecting or lock picking perspective but I wouldn't really feel good about using them occupationally.

Hi,
I am a newbie. I now have 41 pairs. But I am confused about what chain binding is, how you do it, and how it risks security.
Would someone please explain it to me.
Thank you 
Mike

Chain binding is a simple concept really. You basically move both individual handcuffs inward and outward and in a circular motion or whatever motion you want really until the chain links eventually kink or get stuck against the bottom of the handcuffs. 

At this point the chain is basically in a jammed formation and will remain that way as long as you hold the position of the handcuffs in place. You then apply force towards the direction of which the handcuff is stuck and the handcuffs are then vulnerable to either the handcuff inserts snapping which is an obvious weak point of the any chain design or in some cases the handcuff links may actually open depending on the weld quality and strength potential. 

Pretty much all chain models of all manufacturers are affected. Some here argue that you can not apply enough force to snap a handcuff with chain binding while handcuffed behind your back and others argue it's movie prop and can't be done at all. The unfortunate fact is that it can be done with chain handcuffs, it has been done with chain handcuffs, and it will continue to be done with chain handcuffs until some manufacturer finally fixes the problem.

None of them seem to care though and here's your proof.

Peerless has not made any real security improvements to any of their handcuffs in recent time. They could improve the security of their handcuffs by adding more teeth to the pawl, adding double and triple pawl options, adding two bit or three bit or unique bit keying mechanisms, adding pick catches to the ratchet insert, and of course addressing the chain link problem by using rings instead of links.

Smith and Wesson could do the same but they too only have one model that offers elevated security which is M104. And all that does is provide for an exclusive keying design without any of the other security enhancements I mentioned.

I just listed a post on Yuil Y-01K handcuffs having a security key issue. You should check it out in the main thread. It's pretty damning if you ask me. Can't anyone make a secure handcuff today or are we just going to continue to produce children's toys and hope the application in real world use cases doesn't fail?

I don't even know how people can use ASP. The design might look modern but the function isn't for my standards. They feel and function cheap, their locking mechanisms can actually be removed and replaced which scares me, their chain models are most definitely vulnerable to chain binding, and I have a hard time believing they won't eventually break despite the Ultra 'improvements' they claim to have made.

They don't have to make great cuffs, no one is going to pay for them !  Police carry and use guns so escape is NOT an issue.  Better cuffs have been designed, Cuffmaxx and Gotchta but human life is cheap and profit is far better than protecting people. If you consider than too harsh, consider the wearing of masks issue LOL 

I see your point but ask yourself this. How much more money do you really think mass production would cost a manufacturer per unit to add three pawls with rail dividers to a standard chain model, to offer both universal and non-universal keying models of the same design, to offer pick and shim resistance features, and to offer o-rings instead of links to defend against binding with standard backloading and increased rivet strength designs? 1.00-3.00 per unit? Did you ever pay attention to the price of ASP handcuffs? They sell at a premium and they're still being purchased in the masses or ASP wouldn't be selling them. I just dont buy the whole price point issue. Its a valid argument but only to a certain extent.

Also as many of you know there are so many restraints that come from China.. I have seen so many handcuffs sold from China that replicate Smith and Wesson and other makes.. China does have some proprietary designs though which should not be underestimated.. Some Chinese handcuffs are actually very reliable but it depends on what you buy and who actually made them.. I found the following in my research a few days ago..

Original - Senken
https://www.senken-international.com/pr ... 3-912.html

Rebrand - Brifield
Rebrand - Yoghourd 
https://www.amazon.com/Yoghourds-Double ... ast_sto_dp

For those that want a pair of Brifield pickup the Yoghourds above while they last.. they have triple pawl with dividers, a triple bit key, and anti shimming.. They are lightweight and seem to be pretty good cuffs but I have no idea how strong they are in terms of link strength.. 

Some purchaser complained about the key jamming in the reviews but I don't see how that's possible.. I just got mine a few days ago and they are smooth and function perfectly.. 

I can tell you Amazon delivers them fast within one day in some markets if you have prime.. Point and case is so many of these handcuffs are simply rebranded and others steal established designs.. You just have to find the source of the product which is sometimes easier said than done.. 

You can find so many product options using alibaba or aliexpress or by performing a more comprehensive search by using google to find inventory on those websites such as 'handcuff suppliers aliexpress' or 'handcuff suppliers alibaba'

I have a set of the "Brifield Knock-Offs" from China. I truly believe the original Brifield was made in China. When Brifield, dropped the design and went to a re-design, that the Chinese maker, rebranded them and sells them currently. I have a knock-off and an original Brifield. They look to be identical.  Side by side, they are the same. The keys transfer between sets as well.

What is your opinion on the strength of the handcuff? The Yoghourds I bought seem of pretty good lightweight metal quality overall but the chain links concern me a little bit. They seem almost like hollow and weak and I'm not sure how much force they could withstand. I doubt they are truly built to NIJ standards but could be wrong.

I agree to that observation. They seem to be weak, in the chain links. Other than that, they are a nice smooth, cuff. Put together, pretty well. The key would also concern me with the thin flags on it. I think they would be easy to break off with repeated use. That has always been a concern with the triple pawl high security models like Yuil, ASP, etc.

Over the past year, I have contacted all of the major domestic & international suppliers of handcuffs for collectors...and no one has (or had) these Brifield C2 handcuffs available for sale.

If you have one for sale, please let me know.

Joe, I got mine from Amazon UK and I think the seller bought them from the manufacturer or wholesaler in China and just branded them 'Brifield' to make them more attractive. The Brifield box is a lot nicer than the plain white one they normally are shipped in.

Joe Fox, the gentleman I bought the Chinese Knock-Offs (orange) cuffs from, my still have more orange or purple? I can check with him, if you like? They are the exact same cuffs. The knock-offs are only missing the serial number stamp and the Brifield box. I also got my original set from UK Amazon, when they were being sold. They were on the market for a really low rate, to start with. The company wanted to get some out there for people to evaluate and spread the word about. Instead of raising the price to a higher retail and continuing with sales, they decided to scrap the first model and do a re-design for a 2nd model. But, i have heard nothing more from them, since then?  I have no idea if a Brifield Model 2 will ever hit the market? Im kind of doubtful, at this point.

The Senken company seems to also offer a H&R Super style model.

THANK YOU all, for the advice!

I just ordered the "knockoff" pair on Amazon.

I would not have known of the '"Yoghourds" re-brand name, otherwise.

The Brifield C2 were ok. Decent for a lock picking challenge but I would not feel comfortable occupationally using them if I had such a job requirement. I would prefer going with a proper big brand and model which were NIJ certified.

The next "rebrander" is Nextorch:

There is also a triple pawl hinged style handcuff.
