A tool distributed by Stage Junk that is known for two things. The first is having a wrench, hole, or slot for almost any nut or bolt for a theatre electrician as well as a pin splitter and continuity tester. The second is its comparably hefty price tag ($75.00 US).
Stage Junk. (Also available in an "economy" version: Standard Focus Tool.)
