Intelligent Recognition: Experimental application of fingerprint unlocking to prevent unauthorized use.
Anti-tampering Design: Such as improved lock cylinder structure to address "lock-picking challenges."
Q: 1. Why are leg iron chains usually much shorter than handcuff chains?
A: This is a functional design. Short chains (usually 5-15 cm) force the wearer to move only in small steps, preventing them from taking normal strides and fundamentally eliminating the possibility of running. Longer handcuff chains allow for necessary upper limb activities (such as maintaining balance and eating), balancing basic living needs with protection against aggression.
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.
