Key Features:

• Material: Typically made from galvanized steel to prevent rust.

• Design: Features sharp barbs (twisted metal spikes) spaced regularly along the wire.

• Types:

  • Single Strand: Basic form with barbs on a single wire.

  • Double Strand: Two wires twisted together for added strength.

  • Razor Wire: Flat, sharp blades instead of traditional barbs (used in high-security areas).

Common Uses:

• Agriculture: Keeping livestock (cows, sheep) within boundaries.

• Security: Preventing unauthorized access to military zones, prisons, and private property.

• Military & Defense: Used in warfare (e.g., trench defenses in WWI).

• Property Boundaries: Marking land divisions cheaply and effectively.

History:

• Invented in 1873 by Joseph Glidden (USA), revolutionizing farming and security.

• Played a major role in World War I as a defensive barrier in trench warfare.

• Legal Considerations:

  • Some regions regulate barbed wire use due to safety concerns (injury risk to humans/animals).

  • Often restricted in urban/residential areas.
