Hi
Sorry John, for late response.
as far i can see , i'm agree that the hilt is aceh style from the shape & size. And the sew on the scabbard also the aceh style. The acehnesse ussually sew the leather on the center of the scabbard. You can see this sew type on some sikin leather scabbard. But I can not identify the blade
as far as i know, the acehnese very rarely made double edge weapon. Most of their weapon is single edge.
