    certainty of steel.

    Yeah… take a few material courses in engineering…

    It’s not so certain a lot of the time…

      The quality of steel has generally gone down in the last hundred years. I’m not trying to dunk on China specifically because cheap steel is manufactured in more places than just there - but I recently saw a stress test of a cheap modern maul made from Chinese steel vs a 100 year old American maul and it’s like they aren’t even in the same category. The old ones were indestructible.
