Raffaello Galiotto: „Evo”. This is the result of partial, circular and concentric cuts made by an inclined diamond disk. Its complexity resides in managing the notch cut by the bulk of the disk along its path which, unlike traditional cuts with constant thicknesses, has cutting cross-sections that differ in function of the given path. Produced by Anzilotti, Pescia (PT), Italy; material: Carrara marble; machine by Denver, Gualdicciolo, Rep. San Marino; model machine: Quota stone 3350/4200.
