Using Tools Safely
Choose and use tools and equipment for cutting, shaping, joining and finishing (scissors, hole punches, saws, sandpaper, glue): match the tool to the material and the job, and explain the safety rules for each
What a learner can do afterwards
- Pick a sensible tool for a job and say why (e.g. a junior hacksaw for a wooden dowel, scissors for card)
- Describe the safety rules for a tool before using it (e.g. cutting away from fingers, clamping wood first)
- Name ways of joining and finishing materials and when each works best (e.g. glue vs tape vs split pins)

Every job needs the right tool. Scissors cut paper and card. A hacksaw cuts wood. Sandpaper smooths rough edges.
Ben wants to cut a wooden dowel. He picks a junior hacksaw, not scissors. He clamps the wood first. He cuts slowly, away from his fingers.
Always ask a grown-up before using a saw or glue gun. Cut away from your fingers, never towards them.
Glue joins paper and card well. Tape holds things for a short time. A split pin lets parts turn. Sandpaper finishes wood so it feels smooth.
Match the tool to the job, learn its safety rule, then pick the best way to join or finish it.

Different Kinds of Saws
Saws are tools that cut things by pushing a row of sharp teeth back and forth. There are many kinds of saws, and each one is best for a different job.
A hack saw is a small saw with a thin blade. It is good for cutting a wooden dowel, a pipe, or a piece of metal. The thin blade lets you make careful, straight cuts.
Bigger saws are for bigger jobs, like cutting large pieces of wood. A small saw, like a junior hacksaw, is easier and safer for a small job like cutting a thin stick of wood.
Always ask a grown-up before you use any saw. Hold the wood still, keep your fingers far away from the blade, and cut slowly.
How a Hole Punch Works
A hole punch is a tool that makes a neat round hole in paper, card, or leather. Some hole punches look like pliers with a handle you squeeze.
To use a hole punch, first look at how big the hole needs to be. Line up the punch where you want the hole. Then squeeze the handle firmly. The punch pushes a small circle out of the material.
Keep your fingers away from the part that punches the hole. Only squeeze when your fingers are clear. A hole punch is a good choice when you need a clean, round hole, instead of cutting one with scissors, which can look messy.
Ask a grown-up to help you line up the punch the first few times you use one.
Tool Safety Rules
Every tool has its own safety rules. Learning the rules before you start keeps your hands and eyes safe.
Before using any tool, put on safety goggles if the job makes small pieces fly off, like sawing or sanding. Roll up loose sleeves so nothing gets caught.
Always cut, saw, or drill away from your body and your fingers, never toward them. Hold the material still, or ask a grown-up to hold it, before you start.
Go slowly. Rushing is when accidents happen. If a tool feels hard to control, stop and ask a grown-up for help.
When you finish, put the tool away safely, with sharp edges covered or pointing down.
Picking the Right Tool for the Job
Before starting a project, gather the right tools first. A hammer and nails join pieces of wood together. A saw cuts wood to the size you need. Safety goggles protect your eyes from flying bits of wood or dust.
Picking the right tool matters. A hammer is for pounding nails, not for cutting. A saw is for cutting, not for joining. Using the wrong tool can be unsafe and can ruin your project.
Before you start, lay out all your tools and materials. Check that you have everything you need. Then ask a grown-up to help you use any sharp or heavy tool safely.
Gluing Paper to Wood
Glue is a good tool for joining paper to wood. Before gluing, sand any rough or splintery spots on the wood with sandpaper. This makes the surface smooth so the paper sticks better.
Brush a thin, even layer of glue onto the wood. Press the paper down firmly and smooth out any bubbles or wrinkles.
Glue works best for joining paper or thin materials to wood. Tape can work for a quick fix, but it does not last as long as glue. For joining two hard pieces of wood, other options like split pins or screws might work better.
Let the glue dry fully before touching the project, so the paper stays in place.
