This came off a thing that looks like a very heavy C-clamp which clamps to a bench and has a round hole on the top so you can clamp something about the size of a 1½" pipe vertical. It's a sheet metal tool, a real oldie. But that's all beside the point. This type of handle is what I'm interested in, whether it has a ball end like this one or not (I left the clamp part on so you can see how it's riveted with soft steel, very clever indeed). But I don't know how to search for it because I don't know what it would be called. "Yoke handle"? "Swivel clamp handle"?????It looks rough because it had been filthy with many layers of paint and rust and I just bead blasted it.
