Using the kitchen knife: Put your child's fingers on the instruction ring to ensure the right position. Let them use it gently to cut soft foods like bananas or mushrooms. When using the peeler, again, follow the instruction ring. Start peeling from the top of the fruit or vegetable and move down slowly. For the finger guard, have your child place it on their hand before handling food. This way, they can hold the food firmly without getting hurt. As for maintenance, wash the tools with mild dish soap and warm water after each use. Dry them thoroughly to prevent the beechwood handles from warping and the stainless - steel blades from rusting. Keep the tools in a dry place, away from moisture. Don't let your child use these tools without adult supervision. Also, make sure to keep the tools out of reach of younger children who may not understand how to use them safely.
