Handcuffs resistant to breaking by binding the chain/swivel

[Parabellum]

Dual-link handcuffs can be pretty easily broken if you bind the chain with the swivel to form a leverage.

Would the handcuffs with the swivel in the center - like Hiatts Darby, Hiatts 1960 and with a tilting lever like in the H&R handcuffs or the Chinese police handcuffs be resistant to this technique? Do you have any ideas what can be done to make the handcuffs proof to this resistant to this method?

Hello,

The best defense i have come across for this is to use the "Hinged" handcuffs since you are unable to leverage them, also there is a device that looks like a box that can be placed over the handcuffs called a "Handcuff Cover" or "Transport Box" that will stop a person from being able to get the links bound up with the swivels.

Regarding the black box over the key holes.
Once on someone and double locked, the black box goes on with a pad lock.

Handcuffs can be applied before transport with black box already on. Pen out and double lock for safety and no longer getting tighter..

Problem is as follows

Person wearing cuffs slams them against the wall.
Double lock is disengaged due to inertia force.

Comb, straight pin, staple, or item of choice is used to shim them open with the transport box still locked and intact.



Now swivel cuffs are broken at the links by putting hands in praying style and forcing wrist out or twisting and binding the chain. It's usually the swivel that breaks before the links.

The hinged cuffs same thing but a rotation in opposite directions causing the bike link to pop.

Both require strong wrists and high pain threshold...

I don't think that one needs much strength to snap the chain link handcuffs:

I am curious if somebody accomplished it cuffed behind the back;)
