I went to a local Korean restaurant tonight where they provided stainless
steel chopsticks to patrons. Any reason what the significance is using
stainless steel as opposed to wooden chopsticks?

That's the traditional korean chopstick. We used them at home. Disposable
wooden chopsticks were preferred in korean restaurants(in korea) over metal
ones, because it's not re-usable and thus feels cleaner. I'm a bit
surprised that you were given metal sticks in korean restaurant. Korean
people don't like that.
