This tool is machined from billet aluminum, so it's really strong, lightweight, and dang near bullet-proof. It'll lighten you wallet by a c-note, but it's worth every penny. They put a lot of thought into this little bugger: It fits most focus knobs known to mankind, breaks screw pin shackles loose, fits a wide variety of C-clamp and other cheeseborough securements, and has a built-in continuity tester with an LED indicator for checking lamps and power plugs (not receptacles). It has a machine-cut knurled traction surface on most faces, too, so it won't slip out of your sweaty hand. The corners are all rounded so it won't poke you either.
Put this on a lanyard and you'll be carrying a whole lot less up the ladder with you. Less stuff up - less stuff to fall back down.
