lol.
TBH I'd love to have a pair of chucks made of Rubber. Like, no swivel or anything, just a chain molded directly into 2 vats of liquid rubber.
I guess if you took a 28" chain and sprayed both ends of it for 10" with flex seal, a whole freakin' lot of it, you'd have pretty much exactly what I'm talking about.
That way the chain would never fly off, the shafts would be weighted, and the rubber would be flexible and rounded to reduce the risk of injury and if you dropped them, on concrete or something, the rubber would absorb the shock as where a pair of wooden chucks would scratch or pit.
