Honing my bolshie" muscle

This took place at a meeting of the Federal Executive. There was a proposal to "rationalise" the position of the Gender Balance Task Force and incorporate the post in to our Candidates Office. Although I am no longer Chair of the group I could not help but feel that this was a retrograde step now that we have begun to find out what works and what doesn't. We won the argument and the status quo remains.

Chief Whip commented in the tea room that my skills in this direction were honed enough and needed no further sharpening. Whatever can he mean?
