These chopsticks are called Hibashi. Hi means fire, and bashi, chopsticks. Hashi (chopsticks) changes to bashi when it comes after hi. I look up my dictionary, and it says a pair of tongs, but I googled tongs and see different shapes. Hibashi is used to handle hot bincho charcoal. Bincho is high quality charcoal, and there are many different kinds, size, and colors.
This is not used for handling hot bincho charcoal, but used as an ornament and support a bamboo ladle in a standing vase in one style of performances. This is my favorite, and I only use this. I think these heads are ducks, but I could be wrong.

These are most common hibashi.
I think right set was made with a tiny hole on top probably to tie with a string.
