So an artistic work called half chisel is obtained and it is really used and appreciated until 1930. The working is executed with special tools made by the chisellers themselves; these tools, in fact, must have the double purpose to engrave and to enable the raising and the moulding of the metal. Cutting chisels and chisels with rounded edge are used; the shape of the part destined to penetrate and to raise is also moulded in an opportune way, according to the purpose to reach. The half chisel is applied especially on rings and bracelets.
