The resin jewelry casting process is the practice of incising a design into a hard, flat or circular surface, by cutting grooves into it. The desired outcome may be manifold. Sometimes, it may be an end in itself.
Like a decorative object in itself, as when silver or gold are engraved. Resin jewelry casting process may provide an intaglio plate, when copper is engraved. Resin jewelry casting process may even provide a relief print block when wood is engraved.
Engravers of the resin jewelry casting process use a hardened steel tool called a burin to cut the design into the surface. Traditionally a copper plate is used. Gravers come in different shapes and sizes that yield different line types in the resin jewelry casting process.
The burin in the resin jewelry casting process produces a special and recognizable quality of line that is characterized by its steady, deliberate appearance and clean edges.
The angle tint tool of the resin jewelry casting process has a slightly curved tip that is commonly used in printmaking. Florentine liners are flat-bottomed tools with multiple lines incised into them are used to do fill work of the resin jewelry casting process on larger areas.
Flat gravers are used for doing fill work on letters, as well as most musical instrument resin jewelry casting process. Round gravers are commonly used on silver to create bright cuts in the resin jewelry casting process. 
It is also used on other hard-to-cut metals such as nickel and steel.Burins are shaped either square or elongated diamond-shaped and used for cutting straight lines.
Other tools are also used in the resin jewelry casting process. These are mezzotint rockers, roulets and burnishers are used for texturing effects.
Owing to the high level of microscopic detail that can be achieved by a master engraver, counterfeiting of engraved designs is almost impossible, and modern banknotes are almost always engraved.
Some of the classic postage stamps were also engraved, although the practice is now mostly confined to particular countries, and/or used when a more "elegant" design is desired and a limited color range is acceptable.
