Tools and Their Uses in Basic Technology

Introduction

Every craftsman, from the carpenter to the electrician, depends on tools to carry out his or her work efficiently and accurately. In Basic Technology, learning to identify tools correctly and understand their uses is one of the most important early skills, because using the wrong tool for a task, or using the right tool incorrectly, can lead to poor results or even injury. This lesson introduces the common categories of tools used in Basic Technology and explains their uses.

Meaning of a Tool

A tool is any device or implement used by hand or by machine to perform a specific task, such as cutting, measuring, joining, shaping, or fastening materials. Tools make work easier, faster, and more accurate compared to using bare hands alone.

Classification of Tools

Tools used in Basic Technology can be broadly classified into the following groups based on their function:

• Measuring and marking tools: Used to measure and mark out dimensions on a workpiece before cutting or shaping.
• Cutting tools: Used to cut or shape materials such as wood, metal, or paper.
• Holding and gripping tools: Used to hold a workpiece firmly in place while it is being worked on.
• Striking tools: Used to deliver a striking force, such as driving nails or shaping metal.
• Joining and fastening tools: Used to join two or more pieces of material together.
• Boring tools: Used to make holes in materials such as wood or metal.

Common Measuring and Marking Tools

• Tape rule/measuring tape: Used to measure length and distance.
• Try-square: Used to check and mark right angles (90 degrees) on a workpiece.
• Marking gauge: Used to mark lines parallel to the edge of a piece of wood.
• Scriber: Used to mark lines on metal surfaces.
• Spirit level: Used to check whether a surface is perfectly horizontal or vertical.

Common Cutting Tools

• Hand saw: Used to cut wood into required sizes and shapes.
• Chisel: Used to cut, shape, or carve wood or metal.
• Hacksaw: Used to cut metal.
• Plane: Used to smoothen and level wood surfaces.
• Scissors and tin snips: Used to cut paper, fabric, or thin sheets of metal.

Common Holding and Gripping Tools

• Vice: Used to hold a workpiece firmly on a workbench while working on it.
• Pliers: Used to grip, bend, or cut small pieces of wire.
• G-clamp/C-clamp: Used to hold pieces of wood or metal together temporarily.

Common Striking Tools

• Hammer: Used to drive nails into wood or to strike other tools such as a chisel.
• Mallet: A wooden or rubber-headed hammer used for delicate striking work without damaging the material.

Common Joining and Fastening Tools

• Screwdriver: Used to drive screws into or out of materials.
• Spanner/wrench: Used to tighten or loosen nuts and bolts.
• Soldering iron: Used to join metal parts, especially in electrical work, using melted solder.

Common Boring Tools

• Hand drill/brace and bit: Used to bore holes in wood.
• Bradawl: Used to make small starter holes for screws in wood.

Proper Care and Maintenance of Tools

Tools should always be kept clean, dry, and properly stored after use to prevent rusting and damage. Cutting tools such as chisels and saws should be kept sharp, since blunt tools are not only less effective but also more dangerous to use because they require more force and can slip easily. Tools should be returned to their designated storage areas after use, and any damaged tool should be reported and repaired or replaced before further use.

Safety Precautions When Using Tools

Before using any tool, students should always check that it is in good condition, use the correct tool for the task, hold tools firmly and correctly, and keep fingers away from cutting edges. Sharp and pointed tools should be carried and passed to others with the sharp end pointing downward or away from people. Protective equipment such as goggles should be worn when necessary, especially during operations that may produce flying particles.

Practical Activity

Visit your school's Basic Technology workshop, if available, and identify five tools you can see. For each tool, state its name, the category it belongs to (measuring, cutting, holding, striking, joining, or boring), and its specific use.

Common Mistakes to Avoid

A common mistake is using a tool for a purpose it was not designed for, such as using a screwdriver as a chisel, which can damage both the tool and the workpiece, or cause injury. Another mistake is failing to secure a workpiece properly with a vice or clamp before cutting or drilling, which can cause the material to slip and lead to accidents.

Revision Questions to Discuss in Class

• List the six main categories of tools used in Basic Technology.
• State two examples of measuring and marking tools and their uses.
• Explain the difference between a hammer and a mallet.
• Why is it important to keep cutting tools sharp?
• Describe two safety precautions to observe when using tools in the workshop.

Summary

Tools are essential devices used to carry out tasks such as measuring, cutting, holding, striking, joining, and boring in Basic Technology. Knowing the correct name, category, and use of each tool, along with proper care and safety practices, helps students work efficiently and safely in the workshop, laying a strong foundation for further technical studies.

Matching Tools to Tasks

An important skill in Basic Technology is learning to select the correct tool for a given task rather than simply picking any available tool. For example, if you need to make a straight, right-angled cut on a piece of wood, you would first use a try-square to mark the right angle, then use a hand saw to make the cut. If you need to join two pieces of wood together temporarily while glue dries, a G-clamp would be the correct tool, not a hammer or a screwdriver. Practising this kind of decision-making helps students develop good judgement, which is valued in every technical trade.

Tools in Everyday Nigerian Trades

In many Nigerian communities, you will notice these same tools being used daily by local artisans. A carpenter's workshop will typically contain hand saws, chisels, planes, and hammers, while a mechanic's toolbox will contain spanners, pliers, and screwdrivers of different sizes. Electricians commonly carry screwdrivers, pliers, and soldering irons in their toolkits. Observing how professionals use these tools in real life helps students connect classroom learning with practical, everyday application.

Why Tool Identification Matters for Examinations

In Basic Technology examinations, students are often asked to identify tools from pictures or descriptions and state their uses. Being able to confidently name a tool, describe its category, and explain its function is therefore not just a practical skill but also an important examination skill that requires regular practice and revision.

Storing Tools Correctly

A tidy workshop with tools stored in their proper places, such as on a tool rack or in a toolbox, saves time, prevents tools from getting lost or damaged, and reduces the risk of accidents caused by tools left lying around on the floor or workbench. Developing the habit of returning every tool to its place immediately after use is one of the most valuable habits a Basic Technology student can build early on.
