Rotary saw

A rotary saw is a tool that can cut things very quickly and easily. It works by spinning a tiny blade around really fast. Imagine a toy top spinning around on the ground - the rotary saw is like a huge version of that, but with a sharp blade instead of a toy. When you turn it on, the blade starts spinning super fast (like a superhero running really really fast) and then you can use it to cut through almost anything. You have to be really careful when using a rotary saw though, because it is very powerful and could hurt you if you don't use it properly. Remember to always ask an adult for help when using power tools and wear safety goggles too!
