engraving

Engraving is a way to create a design or pattern on metal or other materials. It is done by using a tool called an engraving machine. The engraving machine cuts away pieces of the material to create a design or pattern. The pieces of material it cuts away will be gone forever, so the engraving is permanent. Engraving is used to make products like jewelry, name tags, awards and signs. It is also often used to personalize things like gifts, tools, or keepsakes.
