Obviously, you'd use the wooden ones until you could make something better
I was being figurative. I'm still working out wind power to process all these blooms.
The point being, we have all this other immersive, progression-y stuff, but I'm slinging around pounds of molten lead in a cup using chopsticks.
For Realism, it would only be good enough to lift SMALL amounts of metals in SMALL crucibles. Leverage and the slow carbonization of the contact point would weaken the sticks over time for much of anything else.
For Gameplay? Well, no, hence the Cosmetics tag. However, it WILL make my tool wall look better to not have literal splinters next to my gorgeous gear.
As an Aside: We already have Hammers of varying materials that are mostly cosmetic outside of some small durability boosts (unless somebody is out there swingin hammer as a sidearm), and none of THOSE upgrades majorly affect the game, either.
This mainly. For the reasons I've listed above, both realistic and cosmetic, I think new tongs would be a good, low impact, high appeal addition
