Trimmer (electronics)

A trimmer is a small electronic device that you can use to trim, or cut, things like your hair, your fingernails, or even the grass in your yard. It works like a pair of scissors, but instead of using blades, it uses a spinning metal wheel called a "rotary trimmer." When you turn it on, the wheel rotates quickly and you can use it to carefully trim away hairs or things that you don't want. It's like a mini hair-cutting machine!
