A small toothed finishing chisel used with hand or pneumatic percussion for controlled refinement of marble surfaces.
Gradinetto is a smaller or finer toothed chisel used during the finishing stages of marble carving. Le voci del marmo records its use together with the pneumatic hammer and flat chisel during finishing.
Etymology
Italian diminutive related to gradina, the toothed chisel.
Sculptor Notes
The finer scale of the tool allows the sculptor to retain the directional intelligence of a toothed chisel while working closer to the final surface.
