Handcuffs might seem like a relatively modern invention but the need for restraining disorderly or dangerous subjects has existed since prehistoric times.
It is believed that early humans used strips of animal hides to bind the hands and this evolved to the use of primitive rope made from twisted vines and reeds.

During the Bronze and Iron Ages humans learned how to work with metals and they were able to fashion more sophisticated, reusable handcuffs.
These early handcuffs featured locking mechanism that were very basic by today's standards but were nevertheless a significant advancement for that period.

Historical records and literature from ancient Greek and Roman society contain numerous references to felons and prisoners of war
being bound by 'fetters,' 'chains,' and 'irons.' This represented yet another progression in restraining devices, as chains were heavy and
cumbersome enough to make escape or flight extremely difficult.

One of the earliest literary allusions to handcuffs comes from Vergil, a Roman poet,in his description of the god Proteus' captivity.
In those olden days there dwelt in the Carpathian Sea a wily old deity, known by the name of Proteus, possessing the gift of prophecy,
the fruits of which he selfishly denied to mankind. Even if those who wished to consult him were so fortunate as to find him, all their effort to
force him to exert his gifts of prophecy were useless, for he was endowed with the power of changing himself into all things, and he eluded their grasp
by becoming a flame of fire or a drop of water. There was one thing, however, against which all the miracles of Proteus were of no avail,
and of this Arstaeus was aware. So Arstaeus came, as Virgil tells us, from a distant land to consult the famous prophet. He found him on the sea-shore
among his seals, basking in the afternoon sun Quick as thought he fitted handcuffs on him, and all struggles and devices were now of no avail.
Such was then the efficacy of handcuffs even on the persons of the immortal gods.

Having established this remote and honorable antiquity, we are not surprised at the appearance of handcuffs in the fourth century B.C., when the soldiers
of a conquering Greek army found among the baggage of the routed Carthaginians several chariots full of handcuffs, which had been held ready in confident
anticipation of a great victory and a multitude of prisoners.

The Middle Ages saw the rise of manacles and shackles as the primary restraining devices of choice.Though these restraints exhibited more advanced
workmanship than their predecessors, they were not adjustable, so prisoners with smaller wrists were often able to slip out and flee from their captors.

The biggest design breakthrough came in 1862 when an inventor named W.V. Adams patented the familiar ratcheting mechanism that is associated with
modern police equipment. The ratchets were engaged by a small locking apparatus that allowed the cuffs to be adjusted to virtually any size wrist.
Today's law enforcement agencies approve the use of many different types of restraints. These include typical chain link handcuffs,
hinged handcuffs, rigid handcuffs, disposable PlastiCuffs (aka FlexiCuffs or zip-ties), leg and waist restraints to control the prisoner.


The word 'handcuff' is a popular corruption of the Anglo-Saxon 'handcop', i.e., that which 'cops' or 'catches the hands'.
The most common of the many slang expressions used towards the police is 'copper', i.e., he who cops the offending member!

Our HANDCOP was designed in 2015 by 4TAC5.COM (Advanced Training and Consultancy Services).
By taking a prehistoric method of restraint and combining it with modern materials and knowledge of restraint escape and counter escape methods
4TAC5.COM have designed a restraint that is both convenient to carry (can be worn like a bracelet)
and easy to deploy (minimal training required) and when applied correctly (double locked) it is very difficult to escape from.

Beware of copies, if the HANDCOP does not feature Technora Braided Cord and a Diamond Stopper Knot it's not a genuine HANDCOP.
One function of the Technora Braided Cord is to counter the 'friction saw' technique that can be used to remove other non-metallic retraints.


All restraints are temporary. For the restraint to remain effective the prisoner should be kept under constant observation.
This is not always possible during the initial capture phase, prisoner transportation or when the number of detainees exceed the observers.
There are many effective methods of escaping restraints and specialist tools have been developed for this purpose.
Handcuff shims, covert keys, friction saws can be used to exploit weaknesses in the application, design and manufacturing of restraints.


Whilst many manufacturers are adding additional security features to their products to counter escape tools HANDCOP consist of only one part
so there are no weaknesses in the design or manufacturing to exploit. Only poor application of the HANDCOP will provide the opportunity to escape.

The specifications of our HANDCOP requires the prisoner to have access to a cutting implement to remove the restraint when it is double locked.
It is possible to use the HANDCOP with the single friction lock but it is not recommended; always double lock.
The HANDCOP is extremely resistant to abrasion and heat (simple friction saw escape method not effective).
It is also stronger than steel so breaking out is not an option; unless you can generate a force exceeding 960lb!
