Tool – cheat (6)
I believe the answer is:
chisel
<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">tool</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(chisel is a kind of tool)</span><br/ ><br/ >'<span class="explanation-format__original">cheat</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I know that cheat can be written as chisel)</span><br/ ><br/ ></span>
(Other definitions for chisel that I've seen before include "Hammered cutting tool" , "Tool used to shape wood, stone or metal" , "Carpenter's or mason's tool" , "Eg, woodworking tool" , "Slangily cheat with wood-working tool" .)
