A manually guided diamond-wire cutting method used in marble work to make controlled cuts through stone.
Filo diamantato manuale means “manual diamond wire.” The term is documented in the Pietrasanta workshop interviews as a stone-cutting method. Diamond-bearing wire permits stone to be sawn along a controlled path rather than fractured by impact.
Etymology
Italian: filo, “wire,” diamantato, “diamond-coated,” manuale, “manual.”
Sculptor Notes
Wire cutting changes the logic of roughing: a mass can be separated by a planned cut, conserving material and reducing the shock associated with heavy percussion.
