Oh crap I'll tell you just this one time, because I will NEVER again in my life endure the hell called Photobucket.
Tool 4 on the top row is one of a set of switchman's relay leaf wrenches. Back in ancient times, the days of the X-Y switch, every contact leaf on the switch had to be checked for tension and adjusted periodicly by a man employing a spring scale and set of wrenches.
Two wrenches are used on the leaf, one to hold the leaf and the second to bend it into tolerance. It was actually considered a good job because switches lived in air conditioned rooms. Of course most switchmen went deaf listening to hundreds of switches rack into position day after day, but nobody really wanted to talk to switchmen anyhow.
