Hoi Bonk,
Ja, the green pair were my first, no doubt you have seen them in action, and ja, they are the most used of the set. The black ones were sold together with the cutters in a clearence bin, 10 bucks for the three of them, and many uses I have had for them. I could use a good set of vice grips though, for when two pliers will not work 'cause the extra hand is needed, or you got get tons of torque.
"torque, torque, the beast needs more torque..."
Rheostatics, Whale Music, the motion picture soundtrack.
What gets me is that you have every contraption, gadget, tool, motor, etc... where you are at and you were unable to locate one set of pliers in a time of need. Well, I have a tough time imaging this, must be a case of "can't see the pliers for the boxes of cable."
Another thing that troubles me is that the project is incomplete, your "twisties" are a marvel in one way or another, pity, no pliers.
I could drive up Sat night, could look into it if that works out for you.
Take care
