1. Identification of Cutting Tools

Cutting tools are tools designed to remove material by cutting through it. Common cutting tools used in woodwork include:

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

Examples:

• A crosscut saw is ideal for cutting boards into smaller pieces.
• A chisel can create mortises for joints.

2. Uses of Cutting Tools

Each cutting tool has a specific purpose in woodworking:

1. Crosscut Saw: Cuts wood perpendicular to the grain for shorter pieces.
2. Rip Saw: Cuts wood parallel to the grain for longer pieces.
3. Chisel: Shapes wood and creates detailed designs.
4. Plane: Smoothens rough edges for a polished finish.
5. Coping Saw: Makes decorative cuts or curves.

Examples of Usage:

• A tenon saw is commonly used when creating a mortise and tenon joint.
• A plane is used to achieve a smooth tabletop finish.

3. Proper Techniques for Using Cutting Tools

Using cutting tools correctly ensures safety and precision.

General Rules:

1. Select the right tool for the task.
2. Secure the wood firmly before cutting.
3. Hold the tool at the proper angle for the best results.
4. Apply consistent pressure without forcing the tool.
5. Maintain a steady pace to avoid splintering the wood.

Examples:

• When using a crosscut saw, align the saw teeth with the cutting line.
• While carving with a chisel, always push the tool away from your body to avoid injury.
