A heavy, stout stone-working chisel with a broad blunt cutting edge, struck with a metal hammer for aggressive removal during roughing.
Scapezzatore is a heavy hand tool with a stout body and a broad, relatively blunt cutting edge. Le voci del marmo notes that it is struck with a metal hammer and that its cutting surface is slightly inclined so the lower edge contacts the stone before the full impact arrives.
It is especially associated with forceful roughing and the removal of substantial material.
Etymology
From Italian scapezzare / related workshop usage, referring to heavy trimming or knocking away material.
Sculptor Notes
The scapezzatore belongs to the stage where mass matters more than finish. Its geometry is intended to transmit heavy blows without behaving like a delicate finishing chisel.
