A scriber is a hand tool used in metalworking, woodworking,
and other crafts to mark lines on workpieces before cutting or shaping. It
typically features a sharp, hardened steel point designed to scratch the surface
of materials like metal, wood, plastic, or ceramics. The scribed lines act as
guides for precision cutting, drilling, or machining.

Key Features:

1. Material: Made of hardened steel ensuring the tip remains sharp and durable for scratching hard surfaces.
2. Tip: A sharp point dual-ended tool.
3. Handle: a simple rod-like shape ergonomic handle for better grip and control.

Uses:

• Marking: It is used to mark out lines on hard materials
  like metal, wood, or plastic before machining or cutting.
• Layout Work: Assists in laying out the dimensions on a
  workpiece, ensuring precise cuts and measurements.
• Measuring Tools: Often used in conjunction with
  squares, rulers, or calipers to transfer or mark exact measurements.

Applications:

• Metalworking: Commonly used to mark out cutting or
  drilling points on metals.
• Woodworking: Used for precise layout lines, especially
  on harder woods where pencil lines might not be visible.
• Precision Machining: Aids in marking specific points
  and lines before milling, drilling, or turning operations.

A scriber is a fundamental tool for precision marking, ensuring accuracy in
machining and fabrication projects.
