That photo was taken a bit before Bruce had that sort of control. Mike Barney (stilson in hand) was still working for Coopers at this time. Not sure if I ever saw/heard of him cutting up a 'Shifter', but I did witness him once remove a 'nut knurgeler' (as he would call them) from the hand of a very surprised mechanic, and throw it in the rubbish bin after he started his own team.
