I am curious to understand the connection between Sumbawa and Banjarmasin. I have recently acquired a Sumbawa keris, with a Banjarmasin hilt, which is not unsual, and looking on the forum, I have found this Benjarmasin keris

I know there were a lot of exchanges by sea through the Bugis, but why this special connexion, since these two places are pretty remote?
