i hate when people polish old tools to a brilliant sheen.
Leave it out on the damp grass overnight! or maybe for a couple/three days.
Toning down unplated steel is about the easiest thing in life.
If you really want it old looking leave it in the compost pile for a month.
It'll be as crunchy nasty ooky as you please.
Most people only over clean tools that were in sad shape to begin with.
I see the same complaint on the antiques roadshow almost very week.
"If you hadn't refinished it, it would be worth $125,000. "
The dipwicket appraisers are always fantasizing the piece was original mint perfect condition before it was refinished.
But the sad sack butt ugly condition that person probably found it in, would have fetched nothing at all.
In reality, people seldom "work" on perfect antiques.
Yours has a bent head. That's why the jaws don't line up anymore. Not from wear, someone tried to use it on something too big for it. Any tool can be abused and adjustable wrenches often are.
Anybody else ever straighten heads so the jaws line up again? I have done many.
It takes a --big -- vise to absorb the shock, and a confident full hammer swing. Because you have to hit them HarD! And you won't do the big ones.
But anything under 14" long I have straightened back up when I wanted, so the jaws meet up again.
