"Multi-purpose" refers to an item or tool designed to serve multiple functions or uses. For example, a Swiss Army knife can perform various tasks such as cutting, screwing, and opening bottles, making it versatile for different situations. This adaptability is beneficial in saving space and resources, as one item can replace several specialized tools. In various fields, multi-purpose products are valued for their efficiency and practicality. In the kitchen, a blender can be used for making smoothies, soups, and sauces, demonstrating how a single appliance can fulfill diverse culinary needs. This concept is widely applied in design, engineering, and everyday life.
