Doing some engraving is a process of creating an image or text on a hard surface, such as metal or stone, by cutting grooves into it. The term 'ETCH' is often used to describe this process, which involves using a sharp tool to carve the desired design into the material. Engraving can be used to create decorative items, such as jewelry, or to create functional items, such as tools. Engraving is also used in the production of coins and medals.
