“ The most difficult part is the use of the thumb; beginners press the stationary chopstick too hard and make the tip of the thumb so stiff that the other chopstick cannot be freely moved. It is quite easy, when one gets used to the thing, even to move the stationary chopstick a little at the same time as the other. The tips of the chopsticks must always meet. In the hand of a skilled user a needle may be picked up with them; but it is quite enough for ordinary purposes if we can pick a fish or take up a grain of boiled rice. ”
