Table etiquette # 12

Try to use your silverware as noiselessly as possible, 'coz loud clatter of a knife tapping against a plate betrays a lack of finesse...according to Craig Clairborne. And we all agree that it's very annoying.
While using chopsticks (hashi), use the thumb and index finger to hold both the sticks, with the remaining fingers giving support. It is a no no to Japanese to pass food while on the chopsticks. It can only be done during the wake if I am not mistaken.
