But if you are in a more formal chinese dining, which pair of chopsticks do you use?

Chinese food is usually communal and not individually served. So, there needs to be two pairs of chopsticks. Which pair to use? Well, the steel pair is for your personal use, ie put food into your mouth. The black pair it to take food from the main plates to your own plate or bowl.
I recently went back to this restaurant that has this not very common double chopsticks thingy. If you would like to see what I ate, click here.
