Engraving is used to add detail and design in a product. The design to be engraved is transferred on to the product by drawing with one's hands or by tracing the design on to the product from paper. Then, with extra sharp tools called "bullys" the design detail is physically etched out. Different tools are used for varying the depth or thickness as per the guidance of the design team. This process requires an eye for detail and very accurate hand pressure to get the desired result. If not done carefully the engraver runs the risk of injury.
