Yesterday when I have some food in an Japanese restaurant, I suddenly found that why is the head of Japanese chopsticks so sharp?

So I try to find the answer of this question. And then I thought that may because the difference of the food we eat. As we all know, Japan is an island country. So fish may be their main food. Chopsticks originated in China. And when this culture was spread to Japan at about Tang Dynasty, people in Japan may find that it’s hard to separate fish and fish-bone using chopsticks. So they make the head of them sharp to eat fish more easily.
There is another main difference that Japanese chopsticks are shorter than Chinese ones. That reason may be the different ways to eat. Nowadays Chinese people like to eat together which means we need long chopsticks to get the food from a big table. But Japanese followed the ancient tradition to eat separately. So their chopsticks are shorter.
At last, here is a link to the restaurant I mentioned before.
