Q: 1. Are the locks on leg irons and handcuffs interchangeable?
A: Not necessarily. Standards vary by country and system.
• Separate type: Many systems use different keys and lock cylinders for handcuffs and leg irons to increase security, preventing a single key from opening all restraints.
• Universal type: Some systems are designed with a universal key for ease of operation.
• Cascaded type: In a "waist chain-leg iron-handcuffs" combination, it may be designed to be opened sequentially with the same key, improving escort efficiency.
Q: 2. What are the specific metal materials used in handcuffs/shackles? Why are they not easily sawed through?
A: Modern high-quality handcuffs/shackles are typically made of martensitic stainless steel or special alloy steel, and undergo quenching and tempering treatment.
• Hardness: The surface hardness can reach HRC 50-55 (Rockwell hardness), approaching or exceeding that of ordinary hacksaw blades (HRC 45-50). This means the saw blade will "slip" on the handcuffs/shackles, wears out extremely quickly, and is difficult to cut into.
• Toughness: The core maintains a certain degree of toughness to prevent brittle fracture upon impact.
• Rust Resistance: The stainless steel composition ensures corrosion resistance in most environments. Simply put, the materials and processes used to manufacture them are designed to withstand destructive tools.
