A cool tool for those days when you just don't have the patience for chopsticks. Might feel a bit like cheating - but probably worth it anyway. The only thing I am concerned about is how on earth is the 'clip' going to stay stable? Last thing I want is to re-clip the spoon to my chopsticks every ten seconds.
Now that I think about it... Using this fancy thing as an actual spoon might not be the smartest way of utilizing it... How about pouring some soy sauce into the 'spoon' part and dipping sushi in it? Um.. that sounds pretty good....
