Handcuffs and leg irons (often collectively referred to as "restraints") are physical restraint devices used in the judicial and correctional systems to restrict personal freedom. While they serve the same purpose, they differ significantly in design, usage scenarios, and technical details.
Anti-Tightening
This is the most important function. After the double locks are engaged, the ratchet mechanism of the handcuffs is locked. Even under strong pressure or impact, the handcuffs cannot tighten further automatically, preventing accidental injury to the person being handcuffed (such as when the wrist is swollen).
Anti-Pry Lock
The added locking mechanism makes traditional simple unlocking tools such as thin wires and paperclips ineffective, greatly improving security. To open double-lock handcuffs, it is usually necessary to first rotate the key slightly in the opposite direction to disengage the second lock before normal unlocking can proceed.
Surface Treatment
In addition to the original stainless steel color, there is also matte black (painted or phosphated). The black finish is not only for aesthetics or tactical concealment, but more importantly, it provides anti-reflective properties (avoiding detection during law enforcement operations) and a certain degree of corrosion resistance.
Core Hardness
The handcuff rings and lock cylinders are made of specially heat-treated alloy steel, with a Rockwell hardness (HRC) typically above 50, ensuring they are difficult to cut with a hacksaw or pliers (ordinary pliers simply cannot bite through them).
