Saws are tools that cut through things like wood or plastic, just like how your teeth can bite through an apple.
Imagine you have a big block of cheese, and you want to slice it into thin pieces for sandwiches. You could use a knife, but what if the cheese is really hard? That’s where saws come in! A saw is kind of like a very sharp, toothy knife that moves back and forth.
How Saws Work
A saw has lots of tiny teeth along its edge. When you push it through something, like wood or cardboard, those teeth grab little pieces and pull them apart, just like how your front teeth can bite into an apple and pull it apart.
Some saws are hand-held, and you move them back and forth by hand. Others are attached to machines that do all the work for you. Either way, a saw is a tool that helps you cut things easily, like how a knife helps you cut your food at dinner.
Examples
- A child uses a simple hand saw to cut through a branch for a science project.
- A carpenter uses a modern electric saw to quickly cut through thick boards.
