1. Functions of Multi-Purpose Tool Parts

Multi-purpose tools are designed to perform several functions, often combining multiple tools into one device.

Examples:

Swiss Army Knife: Includes a knife blade, scissors, screwdriver, and can opener.
Multi-Tool Plier: Combines pliers, wire cutters, a knife, and a file.

2. Care and Maintenance of Tools

Proper maintenance ensures tools remain functional and safe.

Steps for Maintenance:

Cleaning: Remove dirt and debris after each use.
Lubrication: Apply oil to moving parts to reduce friction.
Sharpening: Keep blades sharp for effective cutting.
Storage: Store tools in a dry place to prevent rusting.

3. Classification and Uses of Special Purpose Tools

Special purpose tools are designed for specific tasks, making them highly efficient for particular operations.

Examples and Uses:

Allen Key (Hex Key): Tightening or loosening hexagonal bolts.
Pipe Wrench: For gripping and turning pipes.
Torpedo Level: Checking the alignment of surfaces.
Compass Saw: Cutting curved or circular shapes.

4. Sketching Special Purpose Tools

Students should practice sketching tools like the Allen key, pipe wrench, and compass saw.
