Sculptor may use it to cheat (6)
I believe the answer is:
chisel
'to cheat' is the definition.
(I've seen this in another clue)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for chisel that I've seen before include "Tool for shaping wood or metal" , "Cutting tool for shaping wood or stone" , "Flat steel tool with a cutting edge" , "Carpenter's tool for shaping wood" , "Tool used to shape wood, stone or metal" .)
