An apple cutter is a special tool that helps you cut apples into small, bite-sized pieces. It's like a mini knife, but instead of having just one blade, it has several blades arranged in a circle. You put the apple cutter on top of the apple, push down, and the blades slice through the apple, separating it into pieces. It's very helpful if you want to eat an apple but don't want to bite into the whole thing, or if you need to cut up apples for a recipe. Just remember to be careful when using it, because the blades are very sharp!
