I believe the answer is:
pick
<span class="explanation-format__ClueExplanation">This clue is a double definition.<br/ ><br/ >'<span class="explanation-format__original">go for</span>' is the first definition.<br/ ><br/ >'<span class="explanation-format__original">tool</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I know that pick is a tool)</span><br/ ><br/ ></span>
(Other definitions for pick that I've seen before include "The best tool" , "tool - it breaks" , "Choose - ground-breaking instrument" , "Selection" , "Choose, select" .)
