Japanese Hibashi (Fire Chopsticks); 2 Pair

First pair are 11 3/8" long, weigh ~2 3/4 0z. They were made of flat brass, then rolled to leave them hollow (for insulation). Fairly old, I believe, but they're unsigned...difficult to be sure.

The boxed pair is perhaps post-war...maybe the label carries a clue about that. 8 1/8" long, ~1 1/8 oz. They're solid brass or nickel-silver (paktong).

What little I know about these has them used in Chado, the tea ceremony. If any of you can add to my meager understanding, I'll be most grateful! Thanks for lookin'!

 

Beautiful, especially the second pair.

As far as I know, the tea ceremony chopsticks are called hashi, not hibashi.

Edit: while googling I found both hashi and hibashi used for tea ceremony chopsticks.
