Signs are some objects that are used to represent other items for some specific purpose. They can either indicate or denote the entity which they signify. They can be natural or conventional, vocal or non-vocal, material or cultural, and can denote and symbolize many things. They are used in astrology, communication, computing, spirituality, religion, linguistics, mathematics, biology, medicine, information, commercially, and in signatures. Another typical use of them is also on signboards, which are used for advertising products, events, etc. They can also be used for education or for warning people. Road Signs are a good example since they can warn people of what is ahead and can also inform people of the safety regulations that driver must know about. Signs may also refer to some event that may occur in the future, and in that case they are known as omens or portents that can either be good or bad. Medically, a sign is called a symptom, which is an indication of some disease or condition that a person has. They are also quite useful with mute people who use their hands to communicate. This is called sign language. Commercially, we can see Signs everywhere we go. Many stores and retail outlets use bright, flashing neon Signs outside their shops just so people notice them. Their prime purpose is to draw your attention and make sure that customers are attracted to them. They are also used to make sure that these customers do not find it difficult to locate a particular store. Traditionally, they were made of wood with the text hand painted on them. However, since the advent of technology there are much quicker, nicer and consistent ways of producing Signs that can also be more permanent. They can be carved, and there is also molded signage available, which has developed with the introduction of plastics in this industry.

Engraving is an art in which the engraver carves a design onto a flat, hard surface. This may result in a decorative object, an intaglio plate or even a relief print block. This is done by many different tools called gravers, which come in many different shapes and sizes. These tools include items such as burins, angle tints, Florentine liners, flat gravers, round gravers, etc. The burin can be either square or an elongated diamond shape, and it used to cut straight lines. There are also other tools such as the mezzotint rockers, roulets and burnishers, which are used to bring a texturing effect to the item. Engraving is an art, which has been carried out since the beginning of the first millennium [B.C]. Before cameras were invented, it was used to create pieces of art, such as paintings.

These days, most Engraving can be found on firearms, metal weaponry, jewellery and musical instruments. With the latest technology and the advent of computer laser, Engraving has been further developed. This can make the process extremely precise. The Engravings can be exceptionally clean and quick and do not require the tools to come in contact with the surface to be engraved.
