1. Identification of Cutting Tools

Cutting tools are used to cut and shape wood into desired sizes and forms. Common examples include:

• Crosscut Saw: For cutting across the grain of wood.
• Rip Saw: For cutting along the grain of wood.
• Tenon Saw: For making precise cuts, particularly in joints.
• Coping Saw: For cutting intricate curves and shapes.
• Chisel: For carving and shaping wood.
• Plane: For smoothing and leveling wood surfaces.

2. Uses of Cutting Tools

Each cutting tool serves a unique purpose:

• Crosscut Saw: To reduce long planks into shorter lengths.
• Rip Saw: To split wood along the grain.
• Chisel: For creating grooves, mortises, and detailed carvings.
• Coping Saw: For artistic work like cutting patterns and curves.
• Plane: To smooth rough wooden surfaces and edges.

Example:

• A tenon saw is used when creating mortise-and-tenon joints in furniture making.

3. Proper Techniques for Using Cutting Tools

Using cutting tools safely and effectively requires the following:

• Choosing the Right Tool: Match the tool to the task at hand.
• Securing the Workpiece: Clamp the wood to a stable surface before cutting.
• Maintaining Proper Grip: Hold the tool firmly and maintain a steady motion.
• Using Correct Angles: Ensure the tool aligns correctly with the material.
• Applying Moderate Pressure: Avoid forcing the tool; let it cut naturally.

Example:
When using a crosscut saw, hold the handle with both hands and use smooth, controlled strokes for clean cuts.
