Bulino engraving: Also call "book-note" engraving in the US, it is a high definition engraving of an images by means

of a small graver using hand force to produce micro lines or micro dots closely packed together in order to produce tonal

density changes. This technique has the capability to define images very well in high detail and creates a great amount of

realism.

Metal inlay: Inlay is the means of inserting precious metals such as silver, gold or platinum into a base material such as

steel. The process involves cutting out the pattern from the base material to the exact shape of the image to be inlaid. The

depth of the cutout is relative to the thickness of the material being inlaid. After the cutout has been leveled, its surface is

undercut to create random edges and the material to be inlaid is then hammered into place causing the precious metal to

flow into the under-cutting edges. The precious metal is then stoned and sanded flush with the base surface. The inlay is

finally shaded, using the “bulino” technique to give volume and realism to the pattern, often an animal.

Metal overlay: Same principle as above, but the precious metal is left "proud" (above) of the base material to create a

three-dimensional engraving. The precious metal can be shaded as above, or just sculpted, or sculpted then shaded.
