Q: 1. What is the core difference between handcuffs and leg irons?
A: They serve different functions.
• Handcuffs: The core function is to control movement and prevent aggression. They restrict the hands, preventing attacking others, self-harm, use of tools, or escape by climbing.
• Leg irons: The core function is to deprive freedom of movement. They restrict the feet, completely eliminating the ability to run, jump, and kick forcefully.
Handcuffs are about "control," leg irons are about "restraint."
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.
