Sculpting tool (6)
I believe the answer is:
chisel
'sculpting tool' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for chisel that I've seen before include "Flat steel tool with a cutting edge" , "Hammered cutting tool" , "Carpentry tool" , "Sharp-edged metal tool" , "Edge tool for the carpenter" .)
