Craftsman "Made in U.S.A.", looks like the wires mic at .014 or so.
Don't know how old it is, but it was originally a real one-piece 1"
wide wheel when I got it. The hub is also bigger than your typical
import wheel, giving it shorter, stiffer wires which has worked well,
it doesn't conform as much and resist my hand pressure better. I've
worn the corners off so it now has a domed rather than a square trim,
if you will. While I could probably reverse it and get a little more
life, or even resharpen it with a grinder, I think it's days are
numbered.
Still, it's held up a lot better than the pair of thin import cheapies
I had on there before. I'm not adverse to getting another quality-
made wire brush, if that's where you're going with this. What would
you recommend?

I think you have the right brush. I'd recommend grinding it rather than
reversing it. If you've worn 20% of the original diameter, plan on replacing it
fairly soon. Consider a Knot-type in .014 for gp duty or .020 for heavier duty
work.

I like the wider working surface of a 1" wide wheel, but this is not a
terribly powerful grinder (1/2hp, if that). I see that the knot
brushes in 6" mostly come in 1/2" width only. Am I asking for trouble
to run knot brushes in pairs or am I better off to just stick to
single wheels and plan on changing them out more often?
Thanks,

The knot-type will do a lot heavier work but you're right about the increased HP
requirements. All in all, wire wheels are cheap tools, even expensive ones.
