Thanks Detlef...
As Terengganu was basically a coastal country, it just make sense that the use of akar bahar are widely spread across it's region. Hence we have seen many akar bahar keris hilts in the "pipit teleng" or "anak ayam teleng" form - a hilt style associated with Terengganu's famous keris - the Keris Melela / Gelugor.
But again it would be nice to learn whether the Terengganu folks of the old days were really using this material, or it was a newfound trend instead, as older akar bahar hilts were hard to come by, even when the newer version was not that plenty...
However the link of Malay old folks beliefs and the akar bahar otherworldly myths was a good link on the practicality of its place as a hilt material of choice back then, as compared to the classic wooden hilts and ivories.
To me, as much as I loved abstract art, every akar bahar hilt was a surprise, a tell-tale pattern on styles that would never be the same, one after another.
