Chain vs. Hinged Handcuffs
Chain handcuffs connect the two cuffs with a short length of chain, allowing more wrist movement and comfort during extended wear. Hinged handcuffs use a rigid link instead, giving greater control over the subject’s hands at the cost of some flexibility — a common trade-off professionals weigh based on their specific use.
Leg Irons and Flex Cuffs
Leg irons work the same way as handcuffs but are sized and shaped for ankles, used when hand restraint alone isn’t sufficient. Flex cuffs are single-use, disposable plastic restraints — lightweight and fast to apply, but unlike metal cuffs, they can’t be reused once cut off.
Handcuff Keys: Always Carry a Spare
Standard handcuff keys are largely interchangeable across brands, which is exactly why carrying a spare matters — a lost or damaged key with no backup turns a routine restraint into a real problem. Pocket and clip-style keys make it easy to carry a second key separately from your primary set.
