<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">a means to an end</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for tool that I've seen before include "For example, saw" , "Person used by another" , "Instrument, implement" , "Pawn" , "Device, implement" .)
