1. Identification and Classification of Hand Tools

Hand tools are essential for woodworking and are classified based on their functions:

1. Cutting Tools: Tools used to cut wood, e.g., saws, chisels, and knives.
2. Striking Tools: Tools used for hammering or driving nails, e.g., hammers and mallets.
3. Holding Tools: Tools that hold wood in place, e.g., clamps and vices.
4. Measuring and Marking Tools: Tools used for accuracy, e.g., rulers, tape measures, and marking gauges.

2. Care and Maintenance of Hand Tools

Proper care and maintenance of hand tools ensure their longevity and efficiency.

Maintenance Tips:

• Clean tools after use to remove dirt and sawdust.
• Store tools in a dry place to prevent rusting.
• Sharpen cutting tools regularly to maintain effectiveness.
• Apply oil to metal parts to prevent rust.
• Replace worn or broken parts, such as handles or blades.

Examples:

• A rusty saw should be cleaned with sandpaper and oiled to improve performance.
• Blunt chisels can be sharpened using a sharpening stone.

3. Techniques for Using Hand Tools

Using tools correctly improves accuracy and safety.

Correct Techniques:

• Always hold the tool firmly with a steady grip.
• Use the right tool for the job, e.g., a chisel for carving and a hammer for driving nails.
• Keep hands away from the cutting edge or striking area.
• Use a stable work surface to prevent slipping.

4. Sketching Hand Tools

Students should practice sketching basic hand tools, such as a saw, hammer, or chisel, to enhance their familiarity and visualization skills.

5. Selecting Tools for Specific Jobs

Choosing the right tool is crucial for efficiency and precision.

• For cutting wood: Use a saw.
• For smoothing surfaces: Use a plane.
• For driving nails: Use a hammer.
