1. Identification and Classification of Hand Tools

Hand tools are non-powered tools used for woodwork. They are categorized into the following:

1. Cutting Tools: Tools used for cutting or shaping wood, e.g., saws, chisels, and planes.
2. Holding Tools: Tools that hold wood in position during work, e.g., clamps and vices.
3. Striking Tools: Tools used for hammering or driving nails, e.g., hammers and mallets.
4. Measuring and Marking Tools: Tools used for precision and accuracy, e.g., rulers, tape measures, and marking gauges.

Examples:

• A crosscut saw is used for cutting across the grain of wood.
• A chisel is used for carving or shaping wood.

2. Care and Maintenance of Hand Tools

Maintaining hand tools ensures they remain effective and last longer.

Steps for Proper Maintenance:

1. Clean tools immediately after use to remove dirt and sawdust.
2. Store tools in a dry, secure place to avoid rust and damage.
3. Regularly sharpen cutting tools to maintain sharp edges.
4. Apply oil to metal parts to prevent rusting.
5. Inspect tools for damages and repair or replace worn-out parts.

Examples:

• Blunt chisels can be sharpened using a sharpening stone.
• Rusty tools can be cleaned with sandpaper and oiled.

3. Techniques for Using Hand Tools

Using tools correctly improves efficiency and ensures safety.

Correct Techniques:

• Always use the appropriate tool for the task, e.g., a hammer for driving nails.
• Hold tools firmly to maintain control and precision.
• Avoid using excessive force that may damage the tool or wood.
• Position wood securely on a stable surface before working.

4. Sketching Hand Tools

Sketching helps students familiarize themselves with the shapes and functions of tools.

Tools to Sketch:

• A saw
• A chisel
• A hammer

5. Selecting Tools for Specific Jobs

Choosing the right tool for a task ensures precision and reduces wastage.

Examples:

• A handsaw is ideal for cutting wood into specific sizes.
• A clamp holds wood securely during cutting or shaping.
• A plane smoothens rough wood surfaces.
