What is the difference between a tool and supply?

A tool is a device or implement used to carry out a specific function or task, often enhancing efficiency and precision in work. In contrast, a supply refers to materials or items that are consumed or used during a process, such as office supplies or construction materials. While tools are typically durable and reusable, supplies are often expendable and need to be replenished. Essentially, tools aid in performing tasks, while supplies support those tasks.
