Chopsticks recommendations?

LOL! I bet. Problem with vanish, lacquer… anyway…try to buy from reliable sources. Maybe the OP should use metal ones…

Back in the ancient times, they used silver chopsticks to detect poison food.

I have a few pair of woods without (much) coating, after a few washing they look dry and used… Sometimes I put some olive oil to nourish the wood and they look like new again.
