The first evidence for humans engraving patterns are hatched banding upon ostrich eggshells used as water containers found in South Africa in the Diepkloof Rock Shelter and dated to the Middle Stone Age around 60,000 BP. Modern methods today use computer driven (CNC) Lasers and Router Engraving machines to create your message or image. At Day’s Engraving we offer three types of engraving: Router Engraving, Diamond Engraving and Laser Engraving.
