Guilloche is a decorative engraving technique that uses special lathes. Guided manually, these machines draw a precise, intricate, repeated pattern on the metal surface.
Wavy Rank pattern, applied to Olivari model Atena, gives to the handle characterful reflections.
The Rank decoration takes up the classic wavy zigzag motif of traditional guilloche engraving, which lends itself perfectly to the geometrical pureness of the cylinder, creating characterful reflections.
Different to freehand engraving, which is suited to more naturalistic and free decorations, guilloche engraving is typically mechanical and reiterative. It allows for infinite different patterns by varying the parameters of the process, which work in concert with the technician’s technical sensibility and aesthetic judgement.
