Patent ID: 7469695

Claim:
A method for manufacturing a regular polyhedral ornament such as a regular dodecahedron or a regular icosahedron, the method comprising: (a) shaping a stone into a cube, so as to provide a raw cubic workpiece; and (b) a cutting process comprising cutting the cubic workpiece so as to form a regular polyhedron therefrom, the cutting process comprising: (i) marking six eternal surfaces of the cubic workpiece with cutting base lines which define faces determined by geometric features of the regular polyhedron and ridges forming contours of the faces; (ii) cutting the cubic workpiece along the cutting base lines to form first and second faces, having ridges in common, of the regular polyhedron; (iii) drawing auxiliary cutting lines on the first and second faces so as to compensate for portions of cutting base lines erased during the above cutting step; (iv) cutting a third face of the regular polyhedral by cutting along the auxiliary cutting lines and the cutting base lines; and (v) repeating steps (iii) and (iv) above, so as to form remaining faces of the regular polyhedron, including subsequently drawing auxiliary cutting lines in sequence every time a new face of the regular polyhedron is cut, thereby forming the regular polyhedron.
