Unfortunately, I think the steel age never outlasts, in regards artifact permanence, the stone age. That's why our infrastructure is collapsing.
I love to look up facts:
—-
Global steel production in 2022 reached 1,878 million tonnes, barely surpassing the pre-pandemic production of 1,875 million tonnes in 2019.
——
In 2022, it was estimated that there were roughly 180 billion metric tons of crude iron ore reserves globally. These reserves are distributed across identified and yet-to-be-discovered deposits
—-
60 percent of steel is recycled but because more steel is produced than scrapped, recycled steel makes up about 40 percent of the total amount of steel produced. A total of 1085 million tons of steel is recycled a year.

There is a butt load of iron ore to make steel, at least a centuries worth.
And as iron ore gets scarcer it will cost more, other materials will be substituted, more will be recycled, and marginal reserves will become profitable,,,,but the day comes the main uses of steel will taper off to where it will be a rare specialty metal.
There’s still a market for bronze, which steel replaced in common use.
Humans are smart critters, they’ll figure it out.
My father had one 8” Crescent wrench (made for Western Auto) in a drawer when he died and I still have it but I cracked it forty five years ago and retired it. I still occasionally use it for very light duty.
My best 8” Crescent is heavy duty and would take a long cheater bar to crack.
The day will come a common adjustable wrench will cost so much people will have one that they use, instead of my mantra about tools my boys smile when I have them repeat —-
Buy one to use, one to lose, and one to
hide where you know where it is when you need it!
We have too many tools because they are cheap.
